SAFETY INFORMATION

The operator of any mobile radio should be aware of certain hazards comEMER to the operation of vehicular radio transmissions. A list of

several possible hazards is given:

1. Explosive Atmospheres - Just as it is dangerous to fuel a vehicle

with the motor running, similar hazards exist when operating a mobile radio. Be sure to turn the radio off while fueling a vehicle. Do not carry containers of fuel in the trunk of a vehicle if the radio is mounted in the trunk

2. Interference to Vehicular Electronics Systems - Electronic fuel

injection systems, electronic anti-skid braking systems, electronic cruise control systems, etc., are typical electronic systems that may malfunction due to the lack of protection from radio frequency energy present when transmitting. If the vehicle contains such equipment, consult the dealer and enlist their aid in determining the expected performance of electronic circuits when the radio is transmitting.

3. Dynamite Blasting Caps - Dynamite blasting caps may be caused

to explode by operating a radio within 500 feet of the blasting caps. Always obey the "Turn Of f Tw o-Way Radios" signs posted where dynamite is being used.

When transporting blasting caps in your vehicle: a. Carry the blasting caps in a closed metal box with a soft

lining.

b. Leave the radio OFF whenever the blasting caps are

being put into or removed from the vehicle.

4. Radio Frequency Energy - To prevent burns or related physical

injury from radio frequency energy, do not operate the transmitter when anyone outside of the vehicle is within two feet of the antenna.

5. Liquefied Petroleum (LP) Gas Powered Vehicles - Mobile radio

installations in vehicles powered by liquefied petroleum gas with the LP gas container in the trunk or other sealed-off space within the interior of the vehicle must conform to the National Fire Protection Association standard (NFPA) 58 requiring:

• The space containing the radio equipment shall be isolated by a seal

from the space containing the LP gas container and its fittings.

• Outside filling connections shall be used for the LP gas container.

• The LP gas container shall be vented to the outside of the vehicle.

SAFE DRIVING RECOMMENDATIONS FOR USERS OF MOBILE RADIOS RECOMMENDED BY AAA

• Read the literature on the safe operation of the radio.

• Keep both hands on the steering wheel and the microphone in its

hanger whenever the vehicle is in motion.

• Place calls only when vehicle is stopped.

• When talking from a moving vehicle is unavoidable, drive in the

slower lane. Keep conversations brief.

• If a conversation requires taking notes or complex thought, stop the

vehicle in a safe place and continue the call.

• Whenever using a mobile radio exercise caution.

OPERATING RULES AND REGULATIONS

Two-way FM radio systems must be operated in accordance with the rules and regulations of the local, regional or national government

In the United States, the KME radio must be operated in accordance with the rules and regulations of the Federal Communications Commission (FCC). As an operator of two-way radio equipment, you must be thoroughly familiar with the rules that apply to your particular type of radio operation. Following these rules helps eliminate confusion, assures the most efficient use of the existing radio channels, and results in a smoothly functioning radio network. When using your two-way radio, remember these rules:

1. It is a violation of FCC rules to interrupt any distress or emergency

message. As your radio operates in much the same way as a telephone "party line", always listen to make sure that the channel

is clear before transmitting. Emergency calls have priority over all other messages. If someone is sending an emergency message - such as reporting a fire or asking for help in an accident - KEEP OFF

THE AIR!

2. The use of profane or obscene language is prohibited by Federal

law.

3. It is against the law to send false call letters or false distress or

emergency messages. The FCC requires that you keep conversations brief and confine them to business. To save time, use coded messages whenever possible.

4. Using your radio to send personal messages (except in an

emergency) is a violation of FCC rules. You may send only those messages that are essential for the operation of your business.

5. It is against Federal law to repeat or otherwise make known anything

you overhear on your radio. Conversations between others sharing your channel must be regarded as confidential.

6. The FCC requires that you identify yourself at certain specific times

by means of your call letters. Refer to the rules that apply to your particular type of operation for the proper procedure.

7. No changes or adjustments shall be made to the equipment except by

an authorized or certified electronic technician.

IMPORTANT

Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of the United States may be punishable by a fine of up to $10,000, imprisonment for up to two years, or both.

OPERATING TIPS

The following conditions tend to reduce the effective range of two-way radios and should be avoided whenever possible:

• Operating the radio in areas of low terrain, or while under power

lines or bridges.

• Obstructions such as mountains and buildings.

In areas where transmission or reception is poor, some improvement may be obtained by insuring that the antenna is vertical. Moving a few yards in another direction or moving to a higher elevation may also improve communication.

INTRODUCTION

Figure 2 - KME- Display

The KME- includes an eight character 14-segment display and six status icons. The eight character first line is used to display the selected channel, menu items and miscellaneous operating conditions. When the radio is programmed a personality or computer file is downloaded into the radio. The personality defines how the radio will operate and is used to tailor the operation of the radio for each application. Since the KME radio clearly displays alphanumeric characters, an eight character name can be created for each of the following items:

Systems

Channels

Individual Calls

Group Calls

The KME- radio displays the selected channel by displaying the selected channel name as defined in the personality. For example, this is what will appear in the display if the name for channel 4 is defined in the personality as

“Police 1”.

STATUS INDICATORS

The status indicators or icons are located at the bottom of the display and provide an indication of various radio operating characteristics.

The S icon is used for channels in the scan list. The S icon turns on if the selected channel is part of the scan list. The scan list is a group of channels the radio continuously Monitors for activity. This list can be

modified by the radio programmer or by the radio user.

The P1 icon is used for priority 1 channels. The P1 icon turns on when the selected channel is defined as the priority 1 channel or when the radio receives a call on the priority 1 channel. In scan mode, channels defined as priority channels have precedence over non-priority channels. If a priority 1 channel is decoded, the radio will drop a call while on a non-priority channel or a priority 2 channel and then switch to the priority 1 channel to receive the call. This channel will also be scanned more often than non-priority channels and the priority 2 channel.

The SCAN icon indicates the condition of the SCAN mode. The SCAN button is used to toggle scan ON and OFF. When scan is ON, the radio Monitors all the channels in the scan list for any activity. The SCAN icon turns on when the scan mode is enabled.

The P2 icon represents priority 2 channels. The P2 icon turns on when the selected channel is defined as the priority 2 channel or when the radio receives a call on the priority 2 channel. In scan mode, channels defined as priority channels have precedence over non-priority channels. If a priority 2 channel is decoded, the radio will drop a call while on a non-priority channel and then switch to the priority 2 channel to receive the call. This channel will also be scanned more often than other nonpriority channels, but less than the priority 1 channel.

The CG icon represents decode Channel Guard. When the user selects a channel preprogrammed with decode Channel Guard, the CG icon turns on. Channels programmed with Channel Guard only allow the user to hear calls carrying the equivalent Channel Guard tones or digital codes. This reduces the amount of "channel chatter" the user hears.

The PG icon represents selective signaling. When the user selects a channel preprogrammed with Multi-tone or Type 99 tone signaling, the PG icon turns on. Selective signaling is used to initiate individual calls, group calls, all calls, etc. When the radio is in the Monitor mode the PG icon flashes.

TX/RX INDICATOR

This indicator is located above the EMER button. This indicator contains a red LED and green LED. When the radio is transmitting the red LED turns on. When the radio is receiving a call, the green LED turns on.

ALERT TONES

The KME radio generates a number of unique audible alert tones or

“beeps” to indicate various operating conditions. The alert tone feature can be enabled or disabled through PC Programming. All of the KME alert tones are described in the following sections:

BASIC OPERATION

TURNING THE RADIO ON

Typically, mobile radio installations require the vehicle ignition switch to be in the Accessory or Run position before the radio will power ON. In some applications, the radio is wired directly to the battery and the radio will power ON regardless of the setting of the vehicle ignition. Verify with the installer, how the radio has been connected.

From the OFF position, rotate the ON/OFF Volume knob clockwise until the knob clicks. The radio performs a diagnostic test and then sounds three short tones to indicate the radio has passed the diagnostic test and is ready for operation. The display comes ON and indicates the currently selected channel.

The KME mobile preserves the following data from the previous operating state:

• Channel Number (unless preprogrammed with a power-

• Scan ON/OFF State

• Scan List

• Radio Enable/Disable

up channel)

SELECTING OR CHANGING CHANNELS

Rotate the Channel Selector Knob clockwise or counterclockwise until the desired channel appears in the display.

The Channel Knob is a continuous rotary knob that is used to select the desired channel from a preprogrammed list of channels. Rotate the knob clockwise to increment to the next channel in the list. When the end of the list is reached the radio will wrap to beginning of the list. Rotate the knob counterclockwise to decrement to the previous channel in the list.

CHANGING SYSTEMS

1. Press the M button. This will bring up the KME

radio main menu.

and channel as described in the previous sections.

2. Adjust the volume to the desired level by pressing

and holding the EMER button for at least l second. Noise will be heard if there is no activity on the channel.

3. When the radio receives a call, the green receive

indicator will light and audio will be present at the speaker.

TRANSMITTING A BASIC CALL

1. Make sure the radio is ON. Select the desired

system and channel as described in the previous sections.

2. Observe the TX/RX indicator for any activity on the

channel. Never transmit with the green RX indicator ON.

3. Press and hold the EMER button for at least l second

to Monitor the channel for activity. Noise will be heard if there is no activity on the channel. This will also help in setting the volume level to the desired level.

4. Remove the microphone from the hookswitch.

Holding the microphone approximately 2 inches from your mouth, press the PTT button on the side of the microphone and speak in the microphone.

Always speak in a normal tone of voice. Hold the microphone

cupped in your hand and approximately three (3) inches from your mouth. Shouting will degrade your transmission, so do not speak any louder than normal.

5. When you have finished speaking, release the PTT

button and wait for a reply.

CHANNEL GUARD

Channel Guard is a method of reducing "channel chatter" by equipping receivers with a device that only allows calls with the correct signaling to be heard by the user. Channel Guard is defined in the radio personality.

To Disable Channel Guard (Decode):

If Channel Guard is ON, the CG status indicator will be ON.

Press and release the EMER button (less than l second) to turn decode Channel Guard OFF. The CG status indicator will turn OFF. The radio will always transmit with Channel Guard unless the channel is programmed without Channel Guard.

The radio can be programmed to disable Channel Guard by removing the hookswitch .

To Enable Channel Guard:

If Channel Guard is OFF, the CG status indicator will be OFF.

Press and release the EMER button (less than l second) to turn decode Channel Guard ON. The CG status indicator will turn ON. The radio will always transmit with Channel Guard unless the channel is programmed without Channel Guard.

RADIO MENU OPERATION

There are up to 12 main menu items available. For each main menu item there are multiple submenu items to select from. The features enabled in the radio personality define which main menu items are available and will appear when the radio user accesses the radio menu. The following procedure describes how to access and use the radio menu:

1. Press the M button to access the KME Radio Main

Menu.

2. Press the + button to move to the next item in the

main menu. Press the - button to move to the previous item in the main menu.

3. Press the M button again to select any item from the

menu.

The radio will enter the main menu at the last changed item in the menu. If the menu has not been accessed since the last power cycle, the radio will bring up the first item in the menu list. Table 2 shows how the main menu items will appear in the KME- radio and the KME- radio. The flowchart in Figure 3 shows movement through the entire menu including all submenu items. Error!

SCAN OPERATION

The KME- mobile radio can be set up to scan (Monitor) up to 16 channels on the selected system. The scanned channels may be any frequency within the frequency band limits of the radio. If the radio picks up activity on one of the scanned channels, the radio will switch to the channel and allow the user to receive the call. When the call is done, the radio automatically switches back to the knob-selected channel.

When scan is turned ON, the radio scans all the channels in the scan list. Initially, the scan list is created when the radio is PC Programmed, but the KME radio allows the user to modify the scan list.

The scan list can also include a priority 1 channel and a priority 2 channel. In scan mode, channels defined as priority channels have precedence over non-priority channels. If a call on a priority 2 channel is received, the radio will drop a call while on a non-priority channel and switch to the priority channel to receive the call. If a call on a priority 1 channel is received, the radio will drop a call while on a non-priority channel or a priority 2 channel and then switch to the priority 1 channel to receive the call. Priority channels are also scanned more often than non-priority channels.

The following sections describe how to use the scan feature on the KME- mobile radio.

EMERGENCY OPERATION

Emergency signaling can be transmitted when operating in the conventional mode. Emergency signaling will transmit 5 times with a delay between each transmission. To send an emergency call on the selected conventional system and channel (or on an optionally preprogrammed conventional emergency system and channel), proceed as follows:

Press and hold the red button for approximately one second (this time is programmable and, therefore, could be longer or shorter; check with the system administrator). The radio turns on the TX indicator and proceeds to transmit the pre-programmed emergency signaling sequence.

Emergency signaling is programmed to transmit in one of the following methods:

METHOD 1:

Signaling is transmitted on the selected channel. If the channel is changed the emergency signaling will continue to be transmitted on the newly selected channel.

METHOD 2:

Same as METHOD 1 but the radio will lock on to the currently selected channel. Any attempts to change the system or channel will be disabled.

METHOD 3:

Signaling is transmitted on a pre-programmed conventional emergency system and channel regardless of the selected channel. In this case the selected channel is available for voice transmission and the radio will periodically change to the pre-programmed emergency system and channel to send the emergency signaling and then change back to the selected channel.

METHOD 4:

Same as METHOD 3 but the radio will lock on to the preprogrammed emergency system and channel. Any attempts to change the system or channel will be disabled.

The emergency state can be cleared by turning the radio OFF and then back ON.

TYPE 99 OPERATION

Type 99 is Ericsson’s proprietary method for in-band, two-tone sequential signaling. It is a conventional signaling protocol used to control the muting and unmuting of a radio. This signaling is commonly used for selective calling of individual units or groups of units in a conventional system. Type 99 is typically used in paging operations, where a dispatcher is able to select which radio or radios are to be selectively called.

If Type 99 has been setup, the radio can decode individual, group and supergroup paging calls. When the radio decodes an appropriate Type 99 decode sequence, an alert sounds, the PG icon flashes and the radio enters the Monitor mode.

Receiving An Individual, Group or Supergroup Call

1. Turn scan OFF. The radio cannot receive selective

calls with scan ON. When scan is enabled, the radio automatically switches to the Monitor Mode and Type 99 decode is disabled.

2. Select the proper system and channel as described in

the Basic Operation on page 14.

3. When the radio receives a selective call: À The green TX/RX indicator will turn ON to

indicate the radio is receiving a carrier.

À For an individual call, a single ½ second tone

will sound to indicate the call is an individual call.

For a group call, two short tones will sound to indicate the call is a group call.

For a supergroup call, three short tones will sound to indicate the call is a supergroup call.

Emergency Transmissions

The KME radio can be programmed and installed to send emergency signals. To initiate an emergency call, the Option Cable (KRD 103 133/45) must be installed with a customer supplied emergency button or switch. See the Installation Manual LZT 123 4452 for more information.

Emergency signaling is defined in the personality. The programmable features related to emergency signaling are described below:

v The emergency can be programmed to transmit on the selected

channel, or on a pre-programmed Home/Emergency Channel.

v The emergency can be programmed with or without an

acknowledgement from the base station. If an acknowledgement is required, the radio will display FAIL if the acknowledgement is not received.

v The KME radio can also be programmed to send a silent emergency.

In a silent emergency, the radio transmits the emergency without any indication of a transmission. The TX indicator does not light and all received calls are muted until the user presses the PTT button. The received calls are muted to keep from endangering the user that declared the silent emergency.

To Send An Emergency

Press and hold the emergency button for at least 1 second.

Base Station Calls

In an Enhanced environment, the radio is capable of receiving several unique calls from the base station dispatcher. These calls do not require a response from the user. The following sections describe each type of call.

Interrogate Radio

The interrogate feature allows the dispatch base station to validate the participation of a radio Monitoring the system. The base station sends out a message to a particular radio that includes the radio ID and the interrogate message. If the radio receives a call that includes its own ID and the interrogate message, the radio responds by transmitting its own radio ID back to the base station. The radio receives the call and

responds (transmits) back to the base station without providing any indication to the radio user.

Disable Radio

The radio disable feature allows the dispatch base station to disable any radio Monitoring the system. The base station sends out a message to a particular radio that includes the radio ID and disable message. If the radio receives a call that includes its own ID and the disable message, the radio responds by transmitting its own radio ID back to the base station. After responding to the base station, the radio enters a disabled or kill mode. In the disable mode, the radio will receive calls, but no audio is heard at the speaker. The Push-To-Talk button is also disabled. The radio is disabled for all channels in the system. The radio will only respond to an interrogate call or radio enable call.

Enable Radio

The radio enable feature allows the dispatch base station to reactivate or enable any radio Monitoring the system that had previously been disabled. The base station transmits a call to a particular radio that includes the radio ID and the enable message. If the radio receives a call that includes the its own radio ID and the enable message, the radio responds by transmitting its own radio ID back to the base station. After responding to the base station, the radio exits the disabled or kill mode.

Reset Radios

The reset radio feature allows the base station to reset a particular radio on the system to the selective state. The base station sends out a message to a particular radio that includes the radio ID and the reset message. If the radio receives a call that includes its own ID and the radio reset message, the radio responds by resetting the decoder back to the selective state. The mobile radio does not send an acknowledgement back to the base station.
