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, unless such persons (vehicle occupants or
bystanders, for example) are shielded from the antenna field by a grounded
metallic barrier (such as the user’s vehicle rooftop). The MPE Radius is the
minimum distance from the antenna axis that ALL persons should 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) LIMIT. 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 ANTENNA SYSTEMS, AND 77 INCHES (OR
195 CM) FOR BASE STATION MOUNTED ANTENNA SYSTEMS PER OET
BULLETIN 65 OF THE FCC. THIS ESTIMATE IS MADE USING THE
MAXIMUM CAPABLE POWER OF THE RADIO, ANTENNAS WITH A
MAXIMUM GAIN OF 3 dBd (FOR VEHICULAR MOUNTED SYSTEMS) OR
6 dBd (FOR BASE STATION SYSTEMS), AND A MAXIMUM 50%
TRANSMIT DUTY CYCLE (DUE TO THE PUSH-TO-TALK STATUS OF
THIS MOBILE).
SAFETY TRAINING INFORMATION
YOUR COM-NET ERICSSON PANTHER 300M MOBILE
RADIO GENERATES 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.
IT IS THE RESPONSIBILITY OF THE RADIO OPERATOR TO ENSURE
THAT THE MAXIMUM PERMISSIBLE EXPOSURE LIMITS DETERMINED
IN THE PREVIOUS SECTION ARE OBSERVED AT ALL TIMES DURING
TRANSMISSION. THE RADIO OPERATOR IS TO ENSURE THAT NO
BYSTANDERS COME WITHIN THE RADIUS OF THE MAXIMUM
PERMISSIBLE EXPOSURE LIMITS.
This radio has been examined and complies with the FCC RF exposure limits
when persons are beyond the MPE radius of the antenna. In addition, your
Com-Net Ericsson radio complies 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.
•
American
National
Standards
Institute
(C95.3-1992),
IEEE
Recommended Practice for the Measurement of Potentially Hazardous
Electromagnetic Fields – RF and Microwave.
TO ENSURE THAT YOUR 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 you to exceed FCC RF
exposure limits. A proper antenna for installation on a vehicle has a
maximum gain of 3 dBd. A proper antenna for installation on a rooftop or
tower in a desktop base station setup has a maximum gain of 6 dBd.
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.
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.
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 PANTHER 300M mobile 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:
• 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!
•
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.
•
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.
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 antenna is vertical. Moving a few
yards in another direction or moving to a higher elevation may also
improve communication.

RADIO INDICATORS
Figure 1 – PANTHER 300M mobile radio Front View
Controls
All the controls for the PANTHER 300M mobile radio are located on the front of
the control unit and described below:
ON/OFF Volume Knob
This knob powers the radio ON/OFF and controls the volume level of the
received audio at the speaker. When the knob is in the OFF position, rotate
the knob clockwise until the knob clicks to turn the power to the radio ON. To
turn the power to the radio OFF, rotate the knob counterclockwise until it
clicks and stops. Rotate the knob clockwise to increase the volume of
receive audio. Rotate the knob counterclockwise to decrease the volume of
receive audio.
Typically, mobile radio installations require a 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 vehicle ignition switch setting.
Channel Knob
This six position rotary knob selects the desired channel from a programmed
list of channels. Rotate the Channel Knob clockwise or counterclockwise
until the raised rib aligns with the desired channel number. The displayed
channel number is consistent with the Channel Knob position.

Local/Distant Squelch
The Local/Distant Squelch function toggles the channel squelch setting
between “Local” and “Distant”. “Local” squelch reduces the number of
received degraded transmissions. ”Distant" squelch increases the number of
received transmissions.
Type 99 ON/OFF
The Type 99 function toggles the state of the Type 99 Decoder between
“ON” and “OFF”. Type 99 mutes receive audio until a valid Type 99 call is
received. “ON” indicates the radio is operating in Selective Call mode. ”OFF"
indicates the radio is operating in Monitor mode.
If an invalid or no Type 99 decode is programmed on a channel, the Type 99
function is programmed for an Option button and the Option button is
pressed, the radio will emit a Denied Alert Tone.
Home Channel
The Home Channel function toggles the channel setting between “Home
Channel” and “Selected Channel”. “Home Channel” is a programmed
channel that allows direct communication with a selected individual.
“Selected Channel” is the channel frequency selected by the user. Changing
the channel selection knob or power cycling the radio will cancel the Home
Channel function.
Horn Alert ON/OFF
The Horn Alert ON/OFF function toggles the operation of the Horn Alert of
the Type 99 decoder between “ON” and “OFF”. "ON" will activate the horn
alert relay when a Type 99 Individual Call is received. "OFF" will not activate
the horn alert relay when a Type 99 Individual Call is received.
If an invalid or no Type 99 decode is programmed on a channel, and the
Horn Alert ON/OFF function is programmed for an Option button, and the
Option button is pressed, the radio will emit a Denied Alert Tone.
Enabling the Horn Alert ON/OFF function will enable the Type 99 function.
Disabling the Horn Alert ON/OFF function will not disable the Type 99
function.
Public Address ON/OFF
The Public Address function toggles the operation of the Public Address
operation between “ON” and “OFF”. "ON" will send the microphone audio
through the receive amplifier to the external speaker. "OFF" will send the
microphone audio through the transmitter.
13
External/Internal Speaker
The Internal/External Speaker function toggles the receive audio between the
“Internal” and “External” speaker. "External" activates the speaker relay so
the receive audio goes to the external speaker. "Internal" does not activate
the speaker relay so the receive audio goes to the internal speaker.
Hookswitch Functions
Hookswitch functions are programmable and vary according to the radio
personality.

BASIC OPERATION
Selecting A Channel
Rotate the Channel Knob clockwise or counterclockwise until the raised rib
aligns with the desired channel number.
Transmitting A Basic Call
1. Power ON the radio.
2. Select a channel.
3. Ensure there is no activity on the channel by:
•
checking the TX/RX LED.
•
pressing and holding the Monitor/Clear button. Squelch
noise will be heard if the channel is clear of traffic.
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.
NOTE
Speak in a normal volume. Shouting will degrade your transmission.
5. Release the PTT button after you have finished speaking.
Public Address Message
1. Verify that the Option Status LED for the Option button assigned
with the Public Address function is ON. If it is not, press the Option
button.
2. Set the ON/OFF Volume Knob to the desired public address volume
level. (Generally maximum volume.)
3. 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.
4. When finished, replace the microphone on its hookswitch.
5. Set the ON/OFF Volume Knob to the desired receive volume level.
6. Verify that the Option Status LED for the Option button assigned
with the Public Address function is OFF. If it is not, press the Option
button.
17
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 tones to be heard by the user. Channel 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 noise will be
heard if the channel is clear of traffic.
Digital Channel Guard
Digital Channel Guard performs similar to Channel Guard except sub-audible
codewords are decoded and/or encoded. STE is standard with Digital
Channel Guard operation.
18
Sending DTMF With The DTMF Microphone
The optional DTMF microphone allows the radio to send DTMF signaling.
DTMF may be used in a radio system to access a telephone line or to
perform system control functions.
1. Select a channel. DTMF must be enabled on the channel.
2. Ensure there is no activity on the channel by:
•
checking the TX/RX LED.
•
pressing and holding the Monitor/Clear button. Squelch noise
will be heard if the channel is clear of traffic.
3. Remove the microphone from the hookswitch.
4. "Dial" the required DTMF digits from the telephone keypad on the
microphone. Do not hold the PTT button on the microphone down
while dialing. The DTMF microphone will automatically key the
transmitter.
5. Use the PTT button to transmit voice using the DTMF microphone.
19
SELECTIVE SIGNALING
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 PANTHER 300M mobile radio supports selective signaling in
Type 99 decode format.
In a selective signaling environment, the PANTHER 300M mobile radio
operates in one of two states, Monitor mode or Selective Call mode.
In the Monitor mode, the decoder is disabled and all calls are 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 selective signaling and Channel Guard tones are 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

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 ability to selectively call a radio or a group of
radios.
20
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 channel has Channel Guard, only 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 programmed with
Type 99 ON/OFF function.
•
Allow the "Auto-Reset" timer to reset the Type 99 decoder (only if the
"Auto-Reset" timer in enabled in the radio personality).
21
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 radio will transmit 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 programmed with the Type 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 programmed to deny the use of the transmitter if there is
no voltage on the Ignition A+ line. This feature prevents unauthorized use of
the radio and accidental high current battery drain.
22
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 programmed 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 Ignition A+ option automatically 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 information about the CopyCat Technology and
configuration refer to the Panther 300 Series Maintenance manuals, the OnLine Help in ProGrammer, or contact your system administrator.
