2 SAFETY TRAINING INFORMATION

The M/A-COM P7200 and P5200 portable radios generate RF electromagnetic energy during transmit mode. This radio is designed for and classified as “Occupational Use Only,” meaning it must be used only during the course of employment by individuals aware of the hazards and the ways to minimize such hazards. This radio is NOT intended for use by the “General Population” in an uncontrolled environment.
The P7200 and P5200 portable radio have been tested and comply with the FCC RF exposure limits for “Occupational Use Only.” In addition, these M/A-COM radios comply with the following Standards and Guidelines with regard to RF energy and electromagnetic energy levels and evaluation of such levels for exposure to humans:
• FCC OET Bulletin 65 Edition 97-01 Supplement C, Evaluating Compliance with FCC Guidelines for
Human Exposure to Radio Frequency Electromagnetic Fields.
• American National Standards Institute (C95.1 – 1992), IEEE Standard for Safety Levels with Respect
to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz.
MM23772, Rev. F
• American National Standards Institute (C95.3 – 1992), IEEE Recommended Practice for the
Measurement of Potentially Hazardous Electromagnetic Fields – RF and Microwave.

2.1 RF EXPOSURE GUIDELINES

To ensure that exposure to RF electromagnetic energy is within the FCC allowable limits for occupational use, always adhere to the following guidelines:
CAUTION
• DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may
also cause the FCC RF exposure limits to be exceeded. A proper antenna is the antenna supplied with this radio by M/A-COM or an antenna specifically authorized by M/A-COM for use with this radio (refer to Table 6-1).
• DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). Transmitting more
than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio is transmitting when the “TX” indicator appears in the display. The radio will transmit by pressing the “PTT” (Push-To-Talk) button.
• Always transmit using low power when possible. In addition to conserving battery charge, low power
can reduce RF exposure.
• ALWAYS use M/A-COM authorized accessories (antennas, batteries, belt clips, speaker/mics, etc).
Use of unauthorized accessories may cause the FCC Occupational/Controlled Exposure RF compliance requirements to be exceeded (refer to Table 6-1).
11
• As noted in Table 2-1, ALWAYS keep the device and its antenna AT LEAST 1.1 cm (0.43 inches)
from the body and at least 2.5 cm (1.00 inch) from the face when transmitting to ensure FCC RF exposure compliance requirements are not exceeded. However, to provide the best sound quality to the recipients of your transmission, M/A-COM recommends you hold the microphone at least 5 cm (2 inches) from mouth, and slightly off to one side.

(worst case scenario)

2.2 ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY

During transmissions, this M/A-COM radio generates RF energy that can possibly cause interference with other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as hospitals, aircraft, and blasting sites.
12

3 OPERATING TIPS

Antenna location and condition are important when operating a portable radio. Operating the radio in low lying areas or terrain, under power lines or bridges, inside of a vehicle or in a metal framed building can severely reduce the range of the unit. Mountains can also reduce the range of the unit.
In areas where transmission or reception is poor, some improvement may be obtained by ensuring that the antenna is vertical. Moving a few yards in another direction or moving to a higher elevation may also improve communications. Vehicular operation can be aided with the use of an externally mounted antenna.
Battery condition is another important factor in the trouble free operation of a portable radio. Always properly charge the batteries.

3.1 EFFICIENT RADIO OPERATION

For optimum audio clarity at the receiving radio(s), hold the portable radio approximately two inches from your mouth and speak into the microphone at a normal voice level.
Keep the antenna in a vertical position when receiving or transmitting a message. Do not hold the antenna when receiving a message and, especially, do not hold when transmitting a
message.
MM23772, Rev. F
Do NOT hold onto the antenna when the radio is powered on!

3.1.1 Antenna Care and Replacement

Do not use the portable radio with a damaged or missing antenna. A minor burn may result if a damaged antenna comes into contact with the skin. Replace a damaged antenna immediately. Operating a portable radio with the antenna missing could cause personal injury, damage the radio, and may violate FCC regulations.
Use only the supplied or approved antenna. Unauthorized antennas, modifications or attachments could cause damage to the radio unit and may violate FCC regulations (refer to Table 6-1).

3.1.2 Electronic Devices

RF energy from portable radios may affect some electronic equipment. Most modern electronic equipment in cars, hospitals, homes, etc. is shielded from RF energy. However, in areas in which you are instructed to turn off two-way radio equipment, always observe
CAUTION
the rules. If in doubt, turn it off!
13

3.1.3 Aircraft

3.1.4 Electric Blasting Caps

3.1.5 Potentially Explosive Atmospheres

Always turn off a portable radio before boarding any aircraft! Use it on the ground only with crew permission. DO NOT use while in-flight!!
To prevent accidental detonation of electric blasting caps, DO NOT use two-way radios within 1000 feet of blasting operations. Always obey the "Turn Off Two-Way Radios" signs posted where electric blasting caps are being used. (OSHA Standard:
1926.900)
Areas with potentially explosive atmospheres are often, but not always, clearly marked. These may be fuelling areas, such as gas stations, fuel or chemical transfer or storage facilities, and areas where the air contains chemicals or particles, such as grain, dust, or metal powders.
Sparks in such areas could cause an explosion or fire resulting in bodily injury or even death.
Turn OFF two-way radios when in any area with a potentially explosive atmosphere. It is rare, but not impossible that a radio or its accessories could generate sparks.
14

4 BATTERIES

The P7200 and P5200 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd), Nickel Metal Hydride (NiMH), or Lithium Ion (Li Ion) batteries. Please follow the directions below to maximize the useful life of each type of battery.
Do not disassemble or modify Lithium Ion battery packs. The Lithium Ion battery packs are equipped with built-in safety and protection features. Should these features be disabled or tampered with in any way, the battery pack can leak acid, overheat, emit smoke, burst, and/or, ignite.
If the battery is ruptured or is leaking electrolyte that results in skin or eye contact with the electrolyte, immediately flush the affected area with water. If the battery electrolyte gets in the eyes, flush with water for 15 minutes and consult a physician immediately.

4.1 CONDITIONING BATTERY PACKS

MM23772, Rev. F

4.1.1 Conditioning NiMH Battery Packs

Condition a new NiMH battery before putting into use. This also applies to rechargeable NiMH batteries that have been stored for long periods (weeks, months, or longer). Conditioning requires fully charging and fully discharging the battery three (3) times using a “battery analyzer/conditioner/charger.” M/A­COM recommends either the Cadex
five®
iQ
battery conditioners, purchased directly from M/A-COM. These units condition a battery pack by
automatically charging and discharging (cycling) the battery.
Failure to properly condition NiMH battery packs before initial use will result in shortened performance by the battery.
CAUTION
®
C7400 or the Intelligent Technologies Co. BC3506QP-5 iTECH®

4.1.2 Conditioning NiCD Battery Packs

A new NiCD battery does not require conditioning before use. Periodically condition NiCD batteries to avoid the memory effect. If a NiCD battery is repeatedly charged and not fully discharged, the result is lower voltage and lower capacity. Fortunately, both voltage and capacity are restored through battery conditioning.
Always use M/A-COM authorized chargers and conditioners. Use of unauthorized chargers and conditioners may void the warranty.
CAUTION

4.1.3 Additional Information

For more information regarding the proper care of portable radio batteries or establishing a battery maintenance program, refer to ECR-7367 which may be ordered by calling toll free 1-800-368-3277, then selecting option 7.

4.2 CHARGING BATTERY PACKS

Battery chargers are available from M/A-COM with nominal charge times of one hour. Combinations include single and multi-position, rapid charge units.
M/A-COM chargers are specifically designed for charging nickel-based and lithium ion battery packs. The chargers are chemistry-specific for the battery packs and automatically adjust the charging profiles accordingly. Refer to the appropriate charger manual for specific operating instructions.

4.2.1 Charging Guidelines

Observe the following guidelines when charging a battery pack:
• Avoid high temperature during charging.
• Discontinue use if the charger is overheating.
• Only charge M/A-COM battery packs using a charger approved for use by M/A-COM.
• Do not leave batteries in the charger indefinitely. For best results leave the battery in the charger for
two to six hours after the Green Ready LED comes on. Then place the battery pack into service and fully discharge (as indicated by the radio low battery warning) before re-charging.
If any faults are encountered while charging the battery pack, consult the charger’s manual to determine the cause and possible corrective action.

4.3 BATTERY PACK USAGE

Both nickel-based and Lithium Ion batteries vary in capacity and life. NiCd batteries have a longer life cycle than NiMH batteries whereas NiMH batteries have a larger capacity. However, both Nickel-based and Lithium ion type batteries require basic usage guidelines be followed in order to optimize the battery runtime or shift life.

4.3.1 Usage Guidelines

The following guidelines will help increase the battery runtime or shift life:
• Ensure the battery pack is fully discharged (as indicated by the radio low battery warning) before re-
charging.
• Periodically condition nickel-based battery packs (frequency to be determined based on usage
patterns; refer to ECR-7367). If the battery is fully discharged (to radio Low Battery warning) during routine use, the frequency of conditioning may be extended. Lithium Ion batteries do not suffer from memory-effect and therefore do not require conditioning.
Do not leave any M/A-COM battery in a charger for more than a few days.
16

4.4 CHANGE THE BATTERY PACK

4.4.1 Remove the Battery Pack

5 INTRODUCTION

The P7200 and P5200 series radios are dual-band multi-mode portable radios. The P7200 series radio is available without a front mounted keypad (P7200 only), with a 6-buttoned front mounted keypad, and with a DTMF front mounted keypad (P7200 only). The dual-band (700/800 MHz) P7200 portable radio delivers end-to-end encrypted digital voice and IP data communications. The P7200 and P5200 are designed to support multiple operating modes including:
• OpenSky
• EDACS
• P25 Trunked mode
• P25 Digital Conventional mode
• Conventional Analog mode
The P7200 and P5200 portables can include all of these modes or just one. Additional modes of operation can be added with software updates.
The P7200 and P5200 support a full range of advanced digital trunking features, including voice group calls, priority scanning, emergency calls, late call entry, and dynamic reconfiguration. It performs autonomous roaming for wide area applications. High quality voice coding and robust audio components assure speech clarity.
®
Trunked mode (OTP)
®
or ProVoice™ Trunked mode
MM23772, Rev. F
In the trunked modes, the user selects a communications “operating” system (i.e., OpenSky, EDACS, ProVoice, or P25) and group. While communicating in a trunked mode, channel selection is transparent to the user and is controlled via digital communication with the system controller (e.g. base station in an OpenSky system or a CSD in an EDACS system). This provides advanced programmable features and fast access to communication channels.
In Conventional Analog mode, the user selects a channel and communicates directly on that channel. In this mode, a system refers to a set of channels. A channel is a transmit/receive radio frequency pair.
The exact operation of the radio will depend on the operating mode, the radio’s programming, and the particular radio system. Most features described in this manual can be enabled through programming. Consult your System Administrator for the particular features programmed into your P7200 or P5200.
For further detail about features and operation refer to the appropriate maintenance manual or contact your System Administrator.

8.6 LOG IN TO THE NETWORK

Login occurs either automatically (auto registration) if the radio has a valid registration or, if enabled and authorized for encryption (P7200 only), requires the user to enter a User ID and password.
If encryption is enabled (P7200 only) and authorized on the radio, the user will be prompted to “Pls Login” with the *1 login command, a User ID, and password.
1. Press *1 (Login command).
2. Enter the full 10-digit User ID.
3. Press the # key.
4. Enter the password.
• If the radio is configured for alpha-numeric passwords and the password has consecutive
duplicate numbers (“MES33” for example), enter # between so the radio will not

If necessary, contact radio system administration personnel for log-in assistance and/or radio-specific log in instructions.
29

8.7 LOG OFF THE NETWORK

The *0## command de-registers the radio. Typically, this is automatically performed when powering down the radio. Using this method, the User ID is remembered by the radio so only the password is needed at next log-in. Log-off manually by pressing *0##.

8.8 PERSONALITY

As illustrated in Figure 8-4, a personality defines the profiles and talk groups available to the user. It is the structuring of a collection of profiles and privileges established by the OpenSky network administrator to provide the user with a comprehensive set of profiles to communicate effectively with the necessary talk groups or individuals.
Personalities are stored on the network and downloaded over-the-air to the radio. This process is called “provisioning.” Provisioning occurs at radio power-up (if the personality is not already stored in the radio’s memory) and at user log-in. When changes are made to the personality, the radio is automatically re-provisioned. Each personality can contain up to sixteen (16) profiles and each profile can contain up to sixteen (16) talk groups.

8.8.1 Profiles

As stated above, each profile can contain up to sixteen (16) talk groups. A profile also defines the radio’s emergency behavior. All transmissions are made on the selected talk group (displayed on the top line of the dwell display). The user can change the selected talk group to any of the other talk groups within the profile.

8.8.2 Talk Groups

A talk group represents a set of users that regularly need to communicate with one another. There can be any number of authorized users assigned to a talk group. Talk groups are established and organized by the OpenSky network administrator. An OpenSky talk group is similar to a channel within a conventional FM radio system.

8.13.4 Dual-Tone Multi-Frequency (P7270 only)

Dual-Tone Multi-Frequency (DTMF) is the system used by touch-tone telephones. DTMF assigns a specific tone frequency to each key so a microprocessor can easily identify its activation. This allows for specific tasks such as entering a user ID and password, or selective calling.
When a key on the DTMF keypad is pressed, the DTMF tone is played through the radio’s speaker.

8.17 STEALTH MODE

For some users, it is important to be able to turn off the radio’s display lights and side tones, but not the radio traffic. For example, in covert operations, lights and sounds could inadvertently expose an otherwise unobservable radio user. For this purpose, the radio has a Stealth feature that disables the radio display light, indicator light and audible side tones.
When stealth mode is on, the radio continues to scan the programmed list of talk groups and the user can key-up on the selected talk group.

8.17.1 Enable Stealth Mode

8.18 ADJUST SIDE TONE AUDIO LEVEL

The radio sounds confirming tones called “side tones” when its buttons are pressed. Most users find this audible confirmation helpful when navigating the menus. Side tone audio level can be adjusted or turned completely off using the “Side Menu.”
For covert operations, it may be necessary to turn off side tones. For safety’s sake, turning off the radio during covert operations is not recommended.
If the radio is operating properly but side tones are not heard when the menu buttons are pressed, the side tones are probably turned off. To turn them back on, access the “Side Tone” menu and select a setting other than “off.”

8.20.1 Receive a Voice Call

No action is required on the part of the user. No action is required to receive a voice call. The display responds to incoming voice calls as follows:
• When the dwell display is set to received talk group and the scan mode is Normal or Fixed:
a. If the received talk group matches the selected talk group, then the alias (if available) or user id of
the incoming caller is displayed.
MM23772, Rev. F
b. If the received talk group does not match the selected talk group, then the received talk group
name is displayed.
• When the dwell display is set to received talk group and the scan mode is None, the radio only receives voice on its selected talk group. When the call is received, the alias (if available) or the user ID of the incoming caller is displayed.
• When the dwell display is not set to received talk group, then there is no display indication of an incoming call.

8.20.2 Transmit a Voice Call

1. Select the desired talk group.
2. Depress and hold the PTT button, wait a couple of seconds. If programmed by the administrator, a grant tone will be sounded.
3. Begin speaking into the microphone in a normal voice.
4. For maximum clarity, hold the radio approximately 2 inches from your mouth. Take care not to cover up the microphone while speaking.

or wait a few seconds to return to the dwell display.

8.22 TALK GROUP LOCK OUT

There are two ways to focus voice communications by suppressing calls from talk groups in the active profile.
• No Scan. By changing the Scanning Mode to “No Scan” only the selected talk group is scanned.
• Lock Out. By locking out selected talk groups, background noise or chatter can be eliminated and
scanning resources can be focused on just those groups whose calls you wish to monitor.
Lock out is a listening (receive) function and only blocks received calls on locked out talk groups. Lock out does not affect transmit capability. “No Scan” and “Lock Out” do not apply to recent emergency lock outs.
Only talk groups in the active profile can be locked out, since they are the only talk groups whose voice calls can be heard on the radio. Talk group lock out is a scan-related feature. With lock out, one or more talk groups in the active profile can be temporarily disabled from being scanned. Calls are not received on locked-out talk groups. Lock out settings are not retained between profile changes or when the radio is power cycled.
41
The default emergency and emergency-capable talk groups can be locked out if they are NOT in an emergency state. If a talk group is locked out and is subsequently changed to the currently selected talk group, it will automatically be unlocked by the radio so the user can hear calls on the talk group. The radio may be configured so all talk groups are automatically locked out by default. In this case, they must be manually unlocked, if desired.

8.22.1 Lock Out a Talk Group

8.23 SCANNING

8.23.1 Select Scan Modes

42
Three scanning modes are available for the radio, but only one can be active at any time. Changing the scanning mode changes the way the radio scans voice calls for all of the profiles in the radio personality, no matter which profile is or becomes active.
The choice of scanning mode broadens or narrows the span of communications with all the groups in profiles you listen to, but does not affect your interaction with those groups you talk with.
The scanning modes available for selection may be limited to a subset of the three scanning modes by the administrator.

8.24 MAKE SELECTIVE CALLS

Selective calling is the capability for two voice radio units to obtain and use an independent talk path for a private call. A properly equipped radio can initiate a selective call to any radio in the system that is also programmed for selective calls.
In the OpenSky system, a radio can be configured to initiate selective calls through a pre-programmed list in memory called a speed dial list. Alternatively, a properly equipped radio can initiate a selective call to any radio in the system by entering the ten-digit User ID (similar to a telephone number) of the target radio. Some radios are configured to only receive (not initiate) selective calls.
Selective calls are terminated if an emergency is declared. The network limits selective calls to ten (10) minutes maximum.
44
If a Selective Call is attempted without registration, “No Priv” is displayed.
MM23772, Rev. F

8.24.1 Manually Dialing a Selective Call (P7270 Only)

1. Enter *8, the User ID number of the user being called, and the # key (no dashes or spaces). This feature must be enabled by the administrator.
*8<destination user id># A shortened User ID number can be dialed using the following guidelines:
• If the radio being called is in the same region and agency – enter only the last four digits.
• If the radio being called is in the same region, but a different agency – enter the last seven digits.
• If the radio being called is in another region or if the area is unknown – enter all ten digits.
2. Press PTT (and release) to ring the other user. The ring tone is sounded. If the other user accepts the call, the called user’s alias will appear in initiating caller’s display. The

8.25 SELECTIVE ALERTS

Selective alert messaging is an OTP feature that allows one of up to eight (8) pre-programmed (canned) text messages to be sent from one radio to another. The sender specifies a destination (receiving) radio, selects one of the pre-programmed text messages, and then transmits it to the destination radio. The message delivery system adds sender and time-of-day information and forwards the message to the destination (receiving) radio. The sending radio receives a brief message noting the status of the transmission.
Received messages are stored in the radio until deleted or until the radio is rebooted. Received messages do not survive a reboot.
46

8.25.1 Define Messages

All selective alert messages are pre-defined. The messages are programmed and provisioned remotely by your OpenSky system administrator. The radio user cannot create selective alert message content. The entire selective alert message can be up to 200 characters long.

8.27 EMERGENCY COMMUNICATIONS

The P7200 and P5200 portable radios are capable of sending an emergency alert and making emergency calls on the network. The OpenSky system handles emergency calls with the highest priority, allowing you or the people you serve to get needed help.
Emergency call and alert capability for a profile is configured by the system administrator.
The radio that initiates an emergency alert emits a signal of 3 distinct beeps that only goes to the dispatch console.
Table 8-10: Emergency Calls vs. Emergency Alerts
EMERGENCY ALERT EMERGENCY CALL
An Emergency Alert message is sent to the dispatcher console. All peers (radios and consoles) and the dispatch console play the emergency tone whenever an emergency call is detected. An

emergency tone plays for each new emergency, or when a profile is changed, (assuming there is an emergency on one of the talk groups for the new profile).
If the orange LED is flashing rapidly, the radio is receiving an emergency call. If the LED is flashing every ½ second, the selected talk group is in the emergency state (although not transmitting). If the selected talk group is in the emergency state, an asterisk displays next to the talk group name.
MM23772, Rev. F
In addition to the Emergency Alert signal, the microphone goes hot No emergency audio (voice) transmission (hot-mic) capability available (per programming by system administrator).
for a predetermined length of time to allow for emergency audio
(voice) transmission. The radio declaring the emergency has
channel access priority. Note that the User can also use the PTT
after the pre-determined hot-mic audio transmission, or during to
extend the initial hot-mic audio transmission.

8.27.1 Declare an Emergency Call or Alert

1. Press the red emergency button on the radio to enter emergency mode. Emergency is raised after the
Emergency Raise Delay (configurable via programming). Default is 1 second.
The emergency behavior for the selected profile is configured by the network administrator. This determines whether pressing the Emergency button sends an Emergency Call or just an Emergency Alert. An Emergency Alert is always part of and sent with an Emergency Call.
If the active profile of the unit initiating the emergency is configured to Emergency Alert, the three­beep emergency alert signal is sent only to the dispatcher console.
If the active profile of the unit initiating the emergency is configured to Emergency Call, the three­beep emergency alert signal is sent to the dispatcher console and to all other radios within the selected talk group. The default emergency talk group becomes the selected talk group. The display will
49
alternate between the emergency talk group name and “EMERGENCY” to indicate that the emergency has been initiated.
2. The microphone is hot (open mic) for a programmed amount of time in order to send your voice out on the emergency talk group. All of the radios in the emergency talk group hear your call and see the emergency talk group displayed on their radio.
If the attempt is unsuccessful, “E-PEND” flashes periodically and a retry is queued for 10 seconds. If unsuccessful because of lost sync, retry occurs immediately upon reacquiring sync. On each retry attempt, radio temporarily displays “E-RETRY.” This process repeats until the emergency is successfully declared.

8.27.2 Receive an Emergency Call

Initially, when receiving an emergency call, the radio sounds the emergency tone (three short high­pitched tones).
The radio will flash “EMERGENCY” and display the alias of the user that triggered the emergency or the alias of the talk group (if the incoming talk group is the selected talk group of the receiving radio). When receiving voice in an active emergency, the flashing “EMERGENCY” is inhibited so that the alias of the sender can be seen.
With “No Scan,” only the emergency tone is heard, not the initial open mic transmission. To dismiss or ignore the emergency, refer to Section 8.27.3.

8.27.3 Dismiss an Emergency

The “Dismissing an Emergency” function allows you to “ignore” an emergency declared by another user.
An emergency is dismissed for a configurable amount of time (default = 5 minutes).
1. After receiving an emergency call, press the or button until you see “EmgDismiss.”
2. Press the
to toggle “<” on (dismiss) and off. This works in similar fashion to the lock out menu.
The emergency dismiss timer is cleared when the emergency is cleared.

8.27.4 Clear an Emergency

Check with your system administrator to ensure that your radio is configured with the ability to clear an emergency.
50
To clear the emergency, first press and hold the button. While continuing to hold the button, press the EMERGENCY button. Release both buttons when the Emergency Cleared Tone sounds.
If the radio is in stealth mode, clearing the emergency will cause the radio to exit stealth mode.

8.28 OPENSKY ENCRYPTION (P7200 ONLY)

In the OpenSky network, both data and voice use a 128-bit or 256-bit key encryption standard published by the Federal Information Processing Service (FIPS), called Advanced Encryption Standard (AES). AES is approved by the U.S. Department of Commerce for encryption of classified materials.
When encryption is enabled on the network, data is encrypted from the MDIS to the Mobile End System (MES) (e.g., P7200 portable radio). This form of encryption provides airlink security.
Voice encryption is handled either automatically or manually. Automatic encryption is initiated through the Unified Administration Server (UAS) for a specific talk group and requires nothing from the user. Manual encryption is initiated by two or more radio users. Both methods of encryption are discussed in the following sections.
When a user transmits encrypted voice, any listening users with different encryption keys hear distorted voice and “No Access” appears in the radio display.

8.28.1 Automatic Encryption

For automatic encryption, a system administrator will select the talk group to be encrypted at the interface to the UAS. Once the talk groups have been selected and identified as secure, credentials for key generation are generated automatically by the system and provisioned to authorized users. This process requires that authorized users login to the network and be authenticated. Encryption keys require no manual handling and are never sent “in the clear” over any network interface or airlink.
MM23772, Rev. F
8.28.1.1 Using Automatic Encryption
1. Locate the talk group that has been encrypted at the system administrator level.
2. “Pls Login” appears in the display (unless the keypad was used to log in).
3. Login normally by entering your User ID and Password. If a user is engaged in a call on a talk group encrypted at the network administrator level, “Secure Call”
will appear in the bottom line of the dwell display if the user is logged in to that talk group. If a secure call is in progress elsewhere and the user has not logged in, the bottom of the dwell display
will alternate between “No Access” and the alias of the radio that is currently engaged in the secure call.

8.28.2 Manual Encryption (P7270 Only)

Two or more users can manually encrypt a call, if enabled, without an established encrypted talk group. A pre-determined “key or code” is required. Note that while a user is engaged in an encrypted call, users within the talk group that are not encrypted can still make standard voice calls on that talk group. The encrypted user can hear the standard unencrypted calls, but cannot respond while still manually encrypted.
Manual key entry only affects the currently selected talk group. All available talk groups within the current profile may be independently encrypted.
The key must be pre-determined by the users prior to making a manually encrypted call on a talk group and is entered into the radio using the keypad. For 128 bit encryption, this key is between 1 and 16 digits. For 256 bit encryption, this key is between 17 and 32 digits.
51
8.28.2.1 Using Manual Encryption
1. Press *32 on the keypad.
2. Enter the key (1 – 16 digits for 128 bit encryption; 17 – 32 digits for 256 bit encryption).
3. Press #.
4. To end manual encryption, press *33.
If a user is engaged in a call on a talk group that has been manually encrypted at the radio level, the user will see “Secure Call” on the bottom of the dwell display.
If a secure (encrypted) call is in progress, and the user has not entered the key, the bottom of the dwell display will alternate between “No Access” and the alias of the radio that is currently engaged in the secure call.
Once the user has terminated manual encryption, “UnSecure” appears temporarily in the bottom line of the dwell display.

8.29 DYNAMIC REGROUPING

Dynamic regrouping requires that the network administrator determine which radio users should be formed into an impromptu talk group to respond to particular emergency conditions.
The administrator will edit the personalities of the affected radios to include an emergency profile and then page the affected radios to re-register with the network to receive their edited personalities.
In response, affected radios automatically re-register to receive their edited personalities. During re­registration, subscriber equipment will default to the emergency profile selected by the administrator.

8.30 GPS COORDINATES

The radio’s current latitude and longitude coordinates may be displayed using the “GPS” menu. The following procedure assumes a GPS antenna is connected to the radio and it is receiving adequate signals from GPS satellites:
1. Press
2. Press
or until the “GPS” menu appears in the display. Current GPS coordinate latitude and
longitude data continuously scrolls in the top line of the display in a degrees:minutes:seconds format.
or to change to another menu.
If the internal GPS receiver’s data is expired (30 minutes or more) or unavailable, the radio uses the serving base station’s coordinates [GPS (Site) is displayed]. The GPS Menu will also indicate if the data is aged (2 minutes or more) [GPS (Aged) is displayed].

8.31 V-TAC FUNCTIONS

8.31.1 Extended Coverage Modes (“XCOV” and “XCOV-TG”)
52
In addition to all standard portable radio operating capabilities, Extended Coverage adds the V-TAC’s bridging (vehicular repeat) functionality for accessing the OpenSky radio network. Each portable radio connected to the V-TAC using Extended Coverage is considered a “client” on the V-TAC. Extended Coverage benefits portable radio users since it allows them to get network connectivity using the V-TAC’s higher transmit output power and better antenna system.
MM23772, Rev. F
The V-TAC supports two Extended Coverage modes: Extended Coverage for individual users (XCOV) and Extended Coverage for a talk group (XCOV-TG). Typically, Extended Coverage is used after the vehicle’s operator has exited the vehicle with a portable radio unit and the portable unit requires this bridging functionality to access the OpenSky radio network.
The V-TAC takes advantage of OpenSky’s TDMA capability to eliminate interference between its local and network radio links when operating in an Extended Coverage mode (XCOV or XCOV-TG), an undesirable characteristic of many traditional vehicular repeater systems. Because the V-TAC employs this technology, interference on the network and local radio links is minimized.
A V-TAC in XCOV or XCOV-TG mode sends its alias to clients. The alias is displayed in the second line of the dwell menu of the client, (“VA <alias>”). The client must be connected to a V-TAC running version OTP14.4 or for the V-TAC to provide the alias to the client. If the client is connected to a V-TAC running version OTP14.3.1 or earlier, the client displays “VA None.”

8.31.2 Change Between Extended Coverage Modes

By default, the specific Extended Coverage mode utilized, either XCOV or XCOV-TG, is determined by commands sent to the V-TAC and portable radios from the system administrator or radio installation personnel. In other words, these commands determine which Extended Coverage mode the V-TAC and radios normally use and determine the access method that must be employed by a portable radio to connect to the V-TAC. After commands of this type are sent to the V-TAC and portable radios, each must be rebooted (powered off and then back on) before the change takes effect.
A radio can manually override this command-determined default mode by entering *61 # or *62 # or by using the Client Mode menu option. Command *61 # sets the radio to use the XCOV mode and *62 # sets the radio to use the XCOV-TG mode. However, the connection will only be successful if the V-TAC operating mode matches the manually selected portable V-TAC mode.

8.31.3 Use the XCOV Mode

The Extended Coverage for individual users (XCOV) mode allows up to eight (8) client radios to connect to the V-TAC. The radios have full radio functionality including selective calling and mobile data.
With the Extended Coverage for individual users’ mode (XCOV), V-TAC configuration defines which portable radios are permitted V-TAC access.
Connecting to the V-TAC is automatic or manual, as determined by the system administrator and configuration. Automatic is the preferred mode.
8.31.3.1 Manually Access the XCOV Mode
P7270 Model Radios Only:

to confirm mode selection. The radio reverts to the dwell display and the V-TAC icon is
53

8.31.4 Use the XCOV-TG Mode

When using the XCOV-TG mode, up to thirty (30) client radios can connect to the V-TAC. However, unlike XCOV, radios connected to using XCOV-TG are limited to communicating only on the XCOV-TG talk group and emergency communications. Advanced features such as selective calling and mobile data operations are not available to the XCOV-TG connected clients.
The talk group used for XCOV-TG communications is the talk group that was selected at the V-TAC when it entered XCOV-TG mode. Before a radio can connect to the V-TAC the talk group must be selected on the P7200. If this talk group is not provisioned in the radio’s personality, the radio cannot connect to the V-TAC via the XCOV-TG mode. While connected to the V-TAC via XCOV-TG, a different talk group or profile cannot be selected.
When a portable radio is connected to the V-TAC via XCOV-TG, the V-TAC forwards only the network voice traffic on the XCOV-TG talk groups. Also, data transactions are limited to RRM messages from the V-TAC to the portable radio.
8.31.4.1 Radio Limitations Using XCOV-TG
Portable radios connected to the V-TAC via XCOV-TG will not channel-scan unless they lose radio frequency contact with the V-TAC. If manually enabled, radios will not scan network channels.
The following portable radio keypad functions are disabled when the radio is connected to the V-TAC via the XCOV-TG mode: log-off, manual log-in, alerts, selective calls, PSTN calls, and speed dial calls.
The following portable radio menus are disabled when the radio is connected to the V-TAC via the XCOV-TG mode: alert destination, alert message, alert received, priority talk group, and scan mode. The user cannot change talk group or profile.
8.31.4.2 Access the XCOV-TG Mode
For the Extended Coverage for a talk group mode (XCOV-TG), a portable radio user is granted access and connects to the V-TAC by simply selecting the same Talk Group that the V-TAC had selected when it entered the XCOV-TG mode. Contact the system administrator for questions regarding these aspects.
During XCOV-TG mode operations, the V-TAC will not disconnect portable radios connected to it. A portable radio user must manually disconnect from the V-TAC by pressing *60 # on the radio’s keypad.
However, if the V-TAC is switched out of the XCOV-TG mode, all portable radios will be automatically disconnected from the V-TAC. The radios will continue to look for another V-TAC until manually disconnected (*60 #).

9.3 DISPLAY

The radio display is made up of 3 lines (see Figure 9-4) containing twelve character blocks. Lines 1 and 2 primarily display system and group names. Line 1 also displays radio status messages. The 3rd line is used primarily to display radio status icons. All three lines are used to display menu options when in the menu mode. If programmed, the display backlighting will illuminate upon power up or when radio controls are operated.

9.19 DIGITAL VOICE OPERATION

Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and private (encrypted). The voice modes are programmed on a per-group basis within each trunked system.

9.19.1 Clear Mode

The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be monitored easily by unauthorized persons.
Groups or channels programmed for clear operation cannot transmit or receive digital or private messages.

9.19.2 Digital Mode

The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and channels programmed for digital operation transmit only digital signals. Message trunked group calls and individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or inoperative.
MM23772, Rev. F
If receiving an analog message trunked call, the radio responds in the analog mode during the hang time on the working channel.
If receiving an analog I-Call, the radio responds in the analog mode during the hang time. When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is
transmitted in the mode defined by the system mode as programmed for the current system if the ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I­Call mode programmed in the list for that ID.
The overdial DTMF tones are not available while in the Digital Mode.

9.19.3 Private Mode (P7200 Only)

The Private Mode allows the radio to transmit encrypted messages and receive clear or private transmissions. The radio transmits private if the group/channel is programmed for private operation and forced operation is pre-programmed. If autoselect operation is pre-programmed and the radio is in the Private Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang time is active, the radio transmits private.
Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7) different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio. An individual key is automatically selected on a per-group/channel basis according to the radio programming. Groups and channels within the digital system can be programmed for keys 1-7 (private). Up to 8 banks of 7 keys can be stored for private systems. The bank is specified per system.
When operating on a group or channel programmed for Private Mode, all transmissions are private transmissions and the radio receives clear and private signals. The status icon

If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also, the Private Mode will be enabled if forced operation has been programmed in the radio.
If a group or channel is not programmed for Private Mode operation, PVT DIS will be displayed if an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel in Private Mode.
If the radio does not have the correct encryption key loaded, NO KEY# will be displayed and the call will not be transmitted.
3. Continue with standard transmission procedures. A Private Mode access tone will be heard when the PTT button is pressed.
9.19.4.3 Scanned Group Calls
Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang time, if the radio was programmed for autoselect, it will transmit back in the same mode it received the call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same group was available in private and entered in the scan list, it can receive clear and private calls, provided autoselect was programmed in the radio. The user can select transmitting on the scanned or selected group. If a group is entered in the scan list more than once and in different modes (clear, digital, private), only the first occurrence of the group will be used.

If a new control channel is found, the radio will switch to the new system and sound an alert tone.

9.21.2 Priority System Scan

The radio can also be programmed for Priority System Scan. The priority system is the desired or preferred system. While receiving the control channel of the selected system, the radio will periodically leave the selected system and search for the control channel of the priority system. This is done at a programmable rate defined by the value in the Priority Scan Time control (unless the ProScan is enabled, as explained in the following sections). This priority scan timer is reset each time the PTT button is pressed or when the call is received. If the priority system control channel is found, (or meets the predefined criteria <ProScan>), the radio will automatically switch to the priority system.

algorithm
9.21.2.1 Enabling the Wide Area System Scan Function
If the radio cannot find the control channel of the selected system and begins to wide area system scan, the radio will only scan for the priority system control channel if the priority system is in the wide area scan list.
76
9.21.2.2 When ProScan is Enabled
The radio monitors the priority system and will switch to the priority system if the criteria defined by the controls in the ProScan Options dialog box are met. If ProScan is enabled, the rate at which the radio will
scan for the priority system is defined by the System Sample Time control, located in the ProScan Options dialog box. See Section 9.21.3 for more information on ProScan

9.21.3 ProScan

The radio may be programmed for ProScan system scan operation for multi-site applications depending on the version of radio flash code. ProScan is an improved multi-site system scanning algorithm designed to replace ProSound radio to communicate on, when the selected system drops below a predefined level. This is accomplished by enabling each radio to analyze the signal quality of its current control channel and compares it with the signal quality of the control channel for each site in its adjacent scan list. (The signal quality metric used for the ProScan algorithm is based on a combination of both Received Signal Strength Indicator (RSSI) and Control Channel Verification (CCV) measurements.) When the selected system degrades to a pre­programmed level, the radio will begin to look for a better control channel. Once a control channel that exceeds the pre-programmed parameters is found, the radio will change to the new system and emit a tone (if enabled through programming). If the control channel is completely lost, the radio will enter Wide Area System scanning and search the programmed adjacent systems until a suitable control channel is found.

9.22 EMERGENCY OPERATION

The radio's ability to declare an emergency, clear an emergency, remain locked on an emergency system and group, and the emergency audio and display freeze can each be enabled or disabled through programming. When an emergency is declared scanning will stop and restarts only after the emergency has been cleared.
MM23772, Rev. F

9.22.1 Receive an Emergency Call

When receiving an Emergency Call on the selected group and system, an alert beep is heard and is displayed. The message *RXEMER* flashes in the display on line two until the emergency condition is cleared.

9.22.2 Declare an Emergency Call

To send an emergency call to a selected system and group (or on an optionally pre-programmed group):
1. Press and hold the red EMERGENCY button that is on top of the radio in front of the antenna for approximately one second (this time is programmable and therefore could be longer or shorter; check with the system administrator). The radio will transmit an emergency call request with the radio ID until an emergency channel assignment is received.
2. When the working channel assignment is received, the radio sounds a single beep indicating the radio has auto keyed (see Table 9-4) and is ready for voice transmission. *TXEMER* flashes on line two in the display until the emergency is cleared.
3. Press PTT and speak into the microphone in a normal voice.
4. Release PTT when the transmission is complete.
and momentarily turn ON.

To clear the emergency, first press and hold the button. While continuing to hold the button, press the EMERGENCY button. (This will work if the radio is programmed to clear emergencies.)

9.23 INDIVIDUAL CALLS

9.23.1 Receive and Respond to an Individual Call

When the radio receives an individual call (a call directed only to the user's radio), it un-mutes on the assigned working channel and displays
unit sending the message, or the associated name if the ID number is found in the individual call list. The radio can be programmed to ring when an individual call is received. If enabled, the ring begins five
seconds after the caller un-keys and will continue until the PTT button, the call mode is entered.
The volume of the ring is adjustable through the volume control levels.
If a response is made by pressing the PTT to the call prior to the programmed call-back time-out, the call will automatically be directed to the originating unit. If a response is not made before the call-back time­out, the radio will return to normal receive display, and *WHC* will appear on the first line of the LCD.

9.24.3 Dual-Tone Multi-Frequency: Overdial/Conventional Mode

Once the radio has established a connection to the public telephone system, it may be necessary to “over­dial” more digits to access banking services, answering machines, credit card calls, or other types of systems that require Dual-Tone Multi-Frequency (DTMF) access digits.
Overdial operation can also be used to initiate a telephone interconnect call via DTMF signalling if a dial tone has already been accessed on the system. This method makes a telephone interconnect call while operating in the conventional mode but will also function in trunked mode if a dial tone is directly accessible.
Telephone numbers and other number sequences for overdialing can be stored in the phone list when programming the radio. These numbers are accessed by pressing

9.29 PORTABLE DATA

The P7200 and P5200 series portable radios, when operating in the P25 Trunked or EDACS configuration, permit either voice or data calls to be transmitted or received. The radio can handle only one type of call at a time; however, either data or voice is selected transparently by the operator through normal usage of the radio. Data communications is not supported in the conventional mode.
The radios can be connected to Mobile Data Terminals (MDT) or to a host computer. Any RS-232 compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) may be connected to the radio. Support for MDTs or host computers is a programmable option per radio. Additionally, radios may also be programmed for data only operation (no voice calls transmitted or received).

9.29.1 Displays

The following will be displayed during the various states of data mode of operation:
TX DATA
Appears on top line of display when the radio is transmitting a data call.
RX DATA
DATA OFF
DATA ON
Appears on top line of display when the radio is receiving a data call. Appears on top line of display when the radio is in the data disabled state. Appears for two seconds on top line of display when the radio is toggled to the data
enabled state.

9.29.2 DATA OFF Operation

The radio can be placed in the data disabled state by any of the following methods. When the data state is disabled, DATA OFF appears on the top line of the display.
• Declaring an emergency (not to be used unless an actual emergency condition exists). Alert tone will

9.29.4 Exit Data Calls

Under normal conditions, the radio enters the scan lockout mode and returns to the control channel after completion of a data call (transmit or receive). If, during a data call, one of the following conditions occurs, the data call is immediately terminated and the radio performs the desired function:
• PTT is activated.
• Emergency is declared by pressing the pre-programmed emergency button.
• A group or system is changed.
MM23772, Rev. F

9.29.5 Scan Lockout Mode

Following the transmission or reception of a data call, if scan is enabled, scanning will stop temporarily (two independent pre-programmed times; after a receive data call and after a transmit data call). During this time the scan indicator will flash to indicate that scan is enabled but temporarily suspended. This mode is normally exited when the pre-programmed time expires; however, the following actions will terminate the scan lockout mode before the timeout is completed:
• The CLEAR button is pressed.
• The PTT button is pressed.
• The group or system is changed.
• Phone call mode is entered.
• Individual call mode is entered.
• A new emergency assignment has been received.
• An emergency is declared or cleared.
• An individual or phone call is received.

10.17 DIGITAL VOICE OPERATION

Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and private (encrypted). The voice modes are programmed on a per-channel basis within each conventional system.

10.17.1 Clear Mode

The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be monitored easily by unauthorized persons.
Personality Name
FLASH Software
r - released, 01A - revision state
Copyright
Channels programmed for clear operation cannot transmit or receive digital or private messages.

10.17.2 Digital Mode

The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and channels programmed for digital operation transmit only digital signals. Individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or inoperative.
If receiving an analog I-Call, the radio responds in the analog mode during the hang time. When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is
transmitted in the mode defined by the system mode as programmed for the current system if the ID being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I­Call mode programmed in the list for that ID.
The overdial DTMF tones are not available while in the Digital Mode.

10.17.3 Private Mode (P7200 Only)

The Private Mode allows the radio to transmit encrypted messages and receive clear or private transmissions. The radio transmits private if the group/channel is programmed for private operation and forced operation is pre-programmed. If autoselect operation is pre-programmed and the radio is in the Private Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang time is active, the radio transmits private.
Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7) different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio. An individual key is automatically selected on a per-group/channel basis according to the radio programming. Groups and channels within the digital system can be programmed for keys 1-7 (private). Up to 8 banks of 7 keys can be stored for private systems. The bank is specified per system.
When operating on a group or channel programmed for Private Mode, all transmissions are private transmissions and the radio receives clear and private signals. The status icon
Private Mode is enabled. If the selected group or channel is programmed for auto-select capability, the mode may be toggled between private and clear with the
Radios programmed for forced private operation do not allow a change of the transmit mode.

A series of beeps will begin at the start of the 2 second period and then switch to a solid tone after the keys have been zeroed. The display will indicate KEY ZERO.
