SAFETY INFORMATION
RADIO OPERATOR WARNING
Do not transmit with this radio and antenna when
persons are within the MPE Radius* of the antenna
[see “Determining MPE Radius” in this section], unless
such persons (such as the driver or radio operator) are
isolated from the antenna field by a grounded metallic
barrier (such as the user's vehicle rooftop). MPE Radius is the minimum distance from the antenna axis
that persons should maintain in order to avoid RF
exposure higher than the allowable MPE level set by
the FCC for General Population/Uncontrolled
Exposure, as specified in 47 CFR § 1.1310.
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 FOR
GENERAL POPULATION/UNCONTROLLED EXPOSURE.
The shorter MPE Radius distances listed for the Occupational/
Controlled limits, as specified in 47 CFR § 1.1310, may be used if the
user meets the following conditions:
a) the user is exposed to the RF energy as a consequence of their
employment,
b) the user is aware of their exposure to the RF energy due to their
training by reading this Operator’s manual, and
c) the user exercises control over their exposure. In this case, the
user knows they are using a Push-To-Talk land mobile radio whose
transmitter is rated for a 20% intermittent duty cycle.

Determining MPE Radius*
In the tables following, MPE Radii are listed for ranges of power within
which this radio is intended to operate (20 - 40 Watts) and for antennas
having gains of 0 - 6 dBd (1/4 λλ, quarter-wave monopole = 0 dBd).
In order to determine the MPE Radius for your specific application,
choose the VHF or UHF table that meets either the FCC’s General
Population/Uncontrolled Exposure limits or the Occupational/
Controlled Exposure limits.
Then choose the row containing the appropriate power level into the
antenna and read the MPE Radius on that row under the appropriate
antenna gain. For powers or gains between listed numbers, choose the
next higher listed number in each case.
If you do not know the power level at which the radio is operating
(set by the personality program), assume the maximum of 40 Watts.
If you do not know the gain rating of the antenna, consult the
antenna provider. For antennas of higher gains than listed, consult
the supplier of this radio. If you do not know whether you are
qualified to use the shorter distances as defined by
Occupational/Controlled Exposure limits, then you must use the
longer distances specified by the General Population/Uncontrolled
Exposure limits.

**Example: 450 MHz Band, 40 Watts and 2.5 dBd gain >>> follow 40 Watt row to 3 dBd
column, which yields186 cm (73 in) as the MPE Radius.

MPE NOTES
1. Numbers are calculated for any VHF frequency, since MPE radii is
the same.
2. Numbers are calculated for 450 MHz, giving the largest (worst-case)
MPE radii.
3. Power delivered to antenna: radio output less cable and mismatch
losses.
4. Gains are compared to an ideal, 1/4-wave monopole (1/2-wave
dipole). Add 2.15 dB for comparison with an ideal isotropic source.
(0 dBd = 2.15 dBi)
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 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.
