MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMITS

RADIO OPERATOR WARNING Do not transmit with this radio and antenna when persons are within the
MPE Radius of the antenna, un les s suc h p er sons ( suc h as the dri ver or ra di o operator) are shielded from the antenna fiel d by a grounded m etallic barrier (such as the user’s vehicle rooftop). The MPE Radius is the minimum distance from the antenna axis that pers ons sho ul d maintain in order to avoid RF exposure higher than the allowable MPE level set by the FCC.
FAILURE TO OBSERVE THESE LIMITS MAY ALLOW THOSE WITHIN THE MPE RADIUS TO EXPERIENCE RF RADIATION ABSORPTION WHICH EXCEEDS THE FCC MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIM IT. IT IS THE RESPONSIBILITY OF THE RADIO OPERATOR TO ENSURE THAT THE MAXIMUM PERMISSIBLE
EXPOSURE LIMITS ARE OBSERVED AT ALL TIMES DURING RADIO TRANSMISSION. THE RADIO OPERATOR IS TO ENSURE THAT NO BYSTANDERS COME WITHIN THE RADIUS OF THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS SHOWN BELOW.
Determining MPE Radius THE MAXIMUM PERMISSIBLE EXPOSURE RADIUS HAS BEEN
ESTIMATED TO BE A RADIUS OF ABOUT 55 INCHES (OR 138 CM ) FOR THE VEHICULAR MOUNTED ANTENN A SYSTEMS, AND 77 INCHES (OR 195 CM) FOR BASE STATION MOUNTED ANTENNA SYSTEMS PER OET BULLETIN 65 OF THE FCC. THIS ESTIMATE IS MADE ASSUMING THE MAXIMUM CAPABLE POWER OF THE RADIO IS TRANSMITTED AND ANTENNAS WITH A MAXIMUM GAINS OF 3 dBd ARE USED FOR VEHICULAR MOUNTED SYSTEMS AND 6 dBd FOR BASE STATION SYSTEMS.
A MAXIMUM 50% TRANSMIT DUTY CY CLE IS ASSUMED, DUE TO T HE PUSH-TO-TALK STATUS OF THIS MOBILE.

Transmitter Hazards

The operator of any mobile radio should be aware of certain hazards common to the operation of vehicular radio transmitters. 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.
Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn OFF your radio when in any area with a potentially explosive atmosphere. It is rare, but not impossible that the radio or its accessories could generate sparks.
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 Off Two-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. 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: a. The space containing the radio equipment shall be isolated by a seal
from the space containing the LP gas container and its fittings.
b. Outside filling connections shall be used for the LP gas container. c. The LP gas container shall be vented to the outside of the vehicle.
Page 7

SAFE DRIVING RECOMMENDATIONS

(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.
Page 8

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 P 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:
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 -
The use of profane or obscene language is prohibited by Federal law.
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.
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.
ANTHER
300M mobile radio must be operated in
KEEP OFF THE AIR!
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.
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.
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.
Page 9

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 ensuring that the antenn a is vert ic al. Mov ing a fe w yards in another direction or moving to a higher elevation may also improve communication.

Channel Guard

Channel Guard is a method of reducing "channel chatter" by equipping receivers with tone-responsive devices, which only allow calls with the correct sub-audible to nes to be heard by the user. Chan nel Guard options and parameters are defined in the radio personality.
The radio can be programmed on a per-channel basis to encode and/or decode Channel Guard tones. Squelch Tail Elimination (STE) can be enabled or disabled on a channel programmed with a Channel Guard tone.

Channel Guard Monitor Function

The radio can be programmed, on a per-channel basis to transmit with or without Channel Guard tones. STE can optionally be enabled on a per­channel basis.
Ensure there is no activity on the channel by:
checking the TX/RX LED.
pressing and holding the Monitor/Clear button. Squelch n ois e wi ll be
heard if the channel is clear of traffic.

Digital Channel Guard

SELECTIVE SIGN ALING

Selective signaling controls the muting and unmuting of the receive audio. This allows a user or dispatcher to selectively call an individual radio or group of radios. The P
ANTHER
300M mobile radio supports selective signaling in
Type 99 decode format. In a selective signaling environment, the P
ANTHER
300M mobile radio
operates in one of two states, Monitor mode or Selective Call mode. In the Monitor m ode, the decoder is disabled an d all calls ar e heard by the
user. In the Selective Call mode, the decoder is enabled and only calls intended for
the user will be heard. Selective signaling operates with or without Channel Guard. If Channel
Guard is enabled, the radio can be programmed with an "And" or an "Or" option.
If the "And" option is programmed, only calls with the correct selective signaling AND correct Channel Guard tones are heard by the user.
If the "Or" option is programmed, calls with the correct Channel Guard OR calls with the correct selectiv e signaling an d Channel Gu ard tones ar e heard by the user.
A radio operating in Selective Call mode that receives a selective call switches to the Monitor mode and the TX/RX LED flashes green. The TX/RX LED indicates whether the channel has a carrier signal. The following graphic depicts the flashing pattern of the TX/RX LED.
Monitor mode Without Carrier On
Off
Monitor mode With Carrier On
Off

Type 99 Operation

Type 99 is Com-Net Ericsson’s proprietary method for in-band, two-tone sequential signaling. Type 99 is a conventional signaling protocol that controls the muting and unmuting of a radio. Type 99 encoded base stations, mobiles, or portable radios can selectively call individual units or groups of units in a conventional system. Type 99 is used in paging operations; a dispatcher has the abili t y to select ive ly call a radio or a group of radios.
20
Page 21
If Type 99 is enabled in the radio personality, the radio can decode Individual, Group and Supergroup Type 99 calls. See Table 3 for radio indicator information for each of these types of calls.

Resetting Type 99 After A Call

After decoding a Type 99 call, the radio operates in Monitor mode and all traffic on the channel is audible. If the channe l has Channe l Guard, onl y the traffic with the radio's Channel Guard tone will be heard.
To reset Type 99 operation, use one of the following methods:
Press the Monitor/Clear button.
Press the Option button, only if Option button is program med with
Type 99 ON/OFF function.
Allow the "Auto-Reset" timer to re set th e Type 99 decoder (only if the "Auto-Reset" timer in enabled in the radio personality).
21
Page 22

PROGRAMMABLE PTT FUNCTIONS

Channel Busy Lockout

The radio may be programmed with the Channel Busy Lockout feature, which denies the use of the transmitter when the channel is busy with traffic.
If the PTT button is pressed while the TX/RX LED is ON, the radio will emit an alert tone until the PTT is released.

Channel Guard Channel Busy Lockout

The radio may be programmed with the Channel Guard Busy Lockout feature, which denies the use of the transmitter when the channel is busy with another Channel Guard tone. The r adio will transm it when the channel is busy with the radio's Channel Guard tone.
If the PTT button is pressed while the TX/RX LED is ON and the radio is muted because of an incorrect Channel Guard tone, the radio will emit an alert tone until the PTT is released.

Type 99 Disable After PTT

The radio may be progr ammed with the T ype 99 Disable After PTT feature, which automatically disables the Type 99 decoder after a transmission.
Use one of the methods outlined in the “Resetting Type 99 After A Call” section to reset Type 99 operation.

Ignition Sense Tx Disable

The radio may be progr ammed to deny the use of the trans mitter if there is no voltage on the Ignition A+ line. This feature prevents u nauthorized use of the radio and accidental high current battery drain.
22
Page 23

PROGRAMMABLE HORN ALERT FUNCTION

External Alarms

The Car Horn Alert feature may be programmed to give one of three alarms:
1. Single 1 second alarm
2. Three half second alarm pulses
3. Continuous alarm

Resetting the Car Horn Alert

Programmable features to reset the Car Horn Alert:
Reset the Car Horn Alert after the Type 99 is reset.
Automatically reset the Car Horn Alert.

Car Horn Alert Ignition Sense Option

The radio can be progr ammed to ignore the Car Horn Alert function when Ignition A+ is present. Ignition A+ is usually connected to the vehicle's ignition switch and indicates that the vehicle's engine is running, or in the Accessory position.
The Car Horn Alert option provides notification to somebody outside the vehicle that a Type 99 Individual Call has been received. When the person is inside the vehicle, the Ignit ion A+ option automaticall y disables the Car Horn Alert function.

CLONING

CopyCat Technology, a cloning feature, allows supervisor radios to duplicate radio personalities into subordinate radios on-site without a technician or PC. For more inf ormation about the C opyCat Technolog y and configuration refer to the Pa nther 300 Series Maintenance m anuals, the On­Line Help in ProGrammer, or contact your system administrator.
