CAUTION
SAFETY INFORMATION
Your wireless hand-held portable transceiver contains a low power
transmitter. When the PTT button is pushed (or the VOX mode is enabled)
itsendsoutradio frequency (RF) signals. The device is authorizedtooperate
at a duty factor not to exceed 50%. In August 1996, the Federal
Communications Commissions (FCC) adopted RF exposure guidelines
with safety levels for hand-held wireless devices.
Important: To maintain compliance with the FCC’ s RF exposure guidelines
hold the transmitter at least 1 inch (2.5 centimeters) from your
face and speak in a normal voice, with the antenna pointed up
and away. If you wear the handset on your body while using the
headset accessory, use only the Audiovox supplied carry clip
for this product and ensure that the antenna is at least 1 inch
(2.5 centimeters) from your body when transmitting. Use only
the supplied antenna. Do not use your transceiver with a
damaged antenna. Unauthorized antennas, modifications, or
attachments could damage the transmitter and may violate
FCC regulations.
Performance:
Your transceiver will only achieve its maximum operating range when
communicating with other transceivers across open and flat areas or
between elevated points. Normally occurring environmental factors such
as buildings, trees, terrain and weather, or interference from other radio or
electricalequipment,may have adverse effects onthetransceiver’s effective
range. These are not indicative of a fault condition.
Avoid placing the GMRS6000-2 radio transceiver for prolonged periods of
time in direct sunlight or temperatures below -4°F(-20°C) or above
140°F (60°C).
Place the rubber cover on jacks when not in use.

Channel Selection
In order to communicate with other GMRS/FRS units, both the transmit-
ting and receiving party must be on the same frequency.
The GMRS6000-2 has 22 channels (frequencies) indicated by the large
digits on the LCD display panel. Channels 1 through 7 are the shared
GMRS/FRS channels. Channels 8-14 are FRS only channels, while chan-
nels 15-22 are assigned GMRS only channels. If an FRS only channel (8-
14) has been selected, the HI or LO icon will not be displayed on the LCD
panel; otherwise, for channels 1-7 (GMRS/FRS) and 15-22 (GMRS only)

128-7027

the HI or LO icon will be displayed. Communication with Audiovox GMRS/
FRS and compatible units is possible on these 22 channels. Before trans-
mitting on the selected channel, press the Monitor (M) Button (2) to check
the activity on that channel. If there is activity on the selected channel,
change to another channel that is clear.
To change the channel:
- From GMRS/FRS standby mode, press the MODE button (12) once;
the channel number flashes.
- Press the Up Button (10) briefly to move to the next higher main chan-
nel number.
- Press the Down Button (11) briefly to move to the next lower main
channel number.
- Press the PTT button momentarily to confirm selection.
CTCSS Mode (Sub-Channel) Selection
The Coded Tone Controlled Squelch System (CTCSS) has 38 Sub-Frequencies.
This feature allows you to utilize the coded squelch tones (01-38) within a
main channel and enables you to communicate with another party on the
same main channel using the same subcode. (This filters out unwanted
transmissions from the same main channel). Since there are 38 CTCSS
Sub-channels for each main channel, a different subcode may be se-
lected for each of the 22 channels.
To change the CTCSS Sub-channel:
- FromGMRS/FRSstandby mode, press the MODE Button twice;aflash-
ing oF or sub-channel number is displayed.
- Press the Up or Down button to select the desired sub-channel for
use (01-38 ).
- Press the PTT button to confirm selection.
The CTCSS mode can be turned off by selecting the oF icon as the setting.

NOTE: To communicate with other GMRS/FRS units, they must be
switched to the same channel and CTCSS subcode. To commu-
nicate with other GMRS units that do not have subcodes, switch
your unit to the same channel with the subcode set to oF.
The CTCSS subcodes do not prevent others from hearing your
transmission. This will only allow you to ignore all traffic on a
given channel not using the same subcode.
Transmit Power Selection Mode (GMRS Channels Only)
This feature permits selection of the transmitting power level to high
or low when using channels 1-7 and 15-22. Using low power, the unit
will have a lower transmit range, but battery life will be increased.
NOTE: You will find that for the majority of your needs, the low-power
setting will provide adequate communications on all channels;
there should seldom be any need to use high power, except in
situations where you need absolute maximum range. Using low
power will greatly extend battery life. We suggest you experi-
ment with switching between low and high power.
To access the transmitter power selection function:
- From GMRS standby mode, press the MODE Button 3 times until the
Po indication appears flashing on the display with a steady HI or LO
indication.
- Press the Up or Down button to toggle between the High and Low se-
lections.
- Press the PTT button to confirm selection.
The display will indicate the current setting in standby mode.

Battery Alert
When the battery icon ( ) blinks steadily on the LCD panel, recharge
the unit or install fresh batteries.
NOTESFOR GOOD COMMUNICATION
1 . The GMRS6000-2 22 channels are shared on a ‘take turns’ basis.
This means other groups may be talking on any of the channels.
A common code of ethics/courtesy is to switch to another vacant
channel and not to attempt to talk over someone who is already using
the channel you first selected.
2. The GMRS6000-2 has been designed to maximize performance
and improve transmission range in the field. To avoid interference,
it is recommended that you do not use the units closer than 5 feet
apart.
3. For best transmission results, always keep your mouth about 2-3
inches from the microphone (9) and speak slowly in a normal voice.
4. To increase battery life, use the SCAN feature sparingly. This
feature will reduce operating time considerably.

Warning
•Do not operate the transceiver unless you are licensed to do so.
•Remove the batteries from the transceiver if it is not expected to be used
for long periods. This will eliminate the possibility of chemicals leaking
from the batteries and corroding the transceiver.
•Avoid exposing the transceiver to water or extremes of temperature.
•Do not use this device in or near a mining facility, which uses remotely
triggered explosives or in areas labeled “Blasting Area”. Premature or
accidental detonation may result.
•Do not attempt to modify or in any way increase the output of this
transceiver. Its output is designed to meet the legal limits set by the FCC.
•Do not use this device or change its batteries in potentially explosive
atmospheres as sparks in such areas could result in an explosion.
•Turn your transceiver off wherever posted notices restrict the use of radios
or cellular telephones. Facilities such as hospitals may use equipment
that is sensitive to RF energy.
•Turn your transceiver off on board aircraft when requested to do so.
•Do not place your radio in front of a vehicle’s air-bag. If the air-bag
deploys, it could propel the transceiver like a projectile causing bodily
injury.
