GUIDELINES FOR SAFE AND
EFFICIENT USAGE OF YOUR
RADIO
Important: Read this Information Before Using
Your Portable Radio
OPERATING RULES AND REGULATIONS
Two-way FM radio systems must be operated in
accordance with the rules and regulations of the
FederalCommunicationsCommission(FCC).Asan
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 will help eliminate confusion, assure the most
efficientuseof the existingradio channelsandresult
in a smoothly functioning radio network. The follow-
ing offenses are punishable by fine, imprisonment,
or both.
When using your two-way radio, remember these
rules:
1. It is a violation of FCC rules to interrupt any
distress or emergency message. Asyour radio
operatesinmuchthesamewayasatelephone
"party line", always listen to make sure that the
channel is clear before transmitting. Emer-
gency calls have priority over all other mes-
sages. If someone is sending an emergency
message - suchas reportinga fireor 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.
4. It is against Federal Law to repeat or otherwise
make known anything you overhear on your
radio. Conversations between others sharing
yourchannelmustberegardedasconfidential.
5. No changes or adjustments shall be made to
the equipment except by an authorized or cer-
tified electronic technician.

INTRODUCTION
The portable radio you have purchased will provide
you with reliable two-way communications when
properly used. It is important that you read and
understand this manual to obtain the best possible
performance and long time operation of your radio.
This radio is available in two different versions. One
versionoperatesin theVHFband(151-159MHz)on
one of sixteen (16) user selectable frequencies. The
other version operates in the UHF band (462-470
MHz)ononeofsixteen(16)userselectablefrequen-
cies.
In addition, each version can be set up with one of
thirty-eight (38) user selectable CTCSS tones.
These CTCSS tones help block the reception of
other radio messages that may be on the same RF
frequency as your particular radio. The user may
also disable this feature.
AVAILABLE CHANNEL FREQUENCIES
Each radio operates on one of 16 pre-set frequen-
cies. Refer to Table 1 (VHF) or 2 (UHF) for a listing
of available frequencies. Information is also indi-
cated on frequencies requiring no license or chan-
nels in the General Mobile Radio System (GMRS)
that may be used for personal use only under FCC
Part 95 Rules.
UNPACKING YOUR RADIO
Remove all the items from the packing box and
identify each item. Check off the items as you re-
move them from the box.

OPERATING TIPS
Antenna location and condition is important when
operatingaportableradio.Operatingtheradioinlow
areas or terrain, under powerlinesor bridges, inside
of a vehicleor ina metal orsteel framedbuilding can
severelyreducetherangeoftheunit.Mountainsand
buildings can also reduce the range of the unit.
In areas where transmission or reception is poor,
someimprovementmaybeobtainedbyinsuringthat
the antenna is vertical. Moving a few yards in an-
other 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.
EFFICIENT RADIO OPERATION
Hold the portable radio approximately three inches
from your mouth and speak into the microphone at
a normal voice level.
Keep the antenna in a vertical position when receiv-
ing or transmitting a message.
Do not hold the antenna when receiving a message
and, especially, do not hold when transmitting a
message.
ANTENNA CARE AND REPLACEMENT
Do not use the portable radio with a damaged or
missing antenna. A minor burn may result if a dam-
aged antenna comes into contact with the skin.
Replaceadamagedantennaimmediately.Amissing
antenna could damage your portable radio.
Use only the supplied or approved antenna. Un-
authorized antennas, modifications or attachments
could damage the radio unit and may violate FCC
regulations.
ELECTRONIC DEVICES
RF energy from yourportable radiomay affect some
electronic equipment. Most modern electronic
equipment in cars, hospitals, homes, etc. are
shielded from RF energy. However, in areas that
17

instruct you to turn off two-way radio equipment,
always observe the rules. If in doubt, turn it off.
AIRCRAFT
Always turn off your portable radio before boarding
any aircraft.
•Use it on the ground only with crew permis-
sion
•Do not use it in the air
BLASTING AREAS
To avoid interfering with blasting operations, turn
your radio OFF when in a "blasting area" or in areas
posted "turn off two-way radio". Remote control RF
devices are used by some construction crews to set
off explosives.
POTENTIALLY EXPLOSIVE ATMOSPHERES
Areas with potentially explosive atmosphere are
often, but not always, clearly marked. Thesemay be
fueling areas, such as gas stations, fuel or chemical
transfer or storage facilities, and areaswhere 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 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.
