GT-68 SERIES
FRS Two-way Radio
OWNER’S MANUAL

ATTENTION! The radio is a multitask FRS transceiver. Combining the latest technology in radio
communication along with a sturdy mechanical frame, the radio is the ideal and effective solution for the
professionals who need to stay in touch with the working team (in construction sites, buildings, shows, trade
fairs or hotels) or for leisure users that just want to keep up with friends and family.
To help you ward off bodily injury or property loss that may arise from improper operation, please read all the information
carefully before using our products.
Before operating the radio, please read all safety and operating instructions. Save all instructions in a
safe place for future reference.

Installation of Accessories
Install the Li-ion Battery
To install the batteries:
(1) Turn off the radio. Orient the back of the radio and the battery latch toward you.
(2) Fit the battery to the back of the radio (cover the product nameplate). Squeeze and push the battery pack toward the top
until the battery is locked by the latch.
Remove the battery
(1) Turn off the radio. Orient the back of the radio and the battery latch toward you. .
(2) Press down on the battery latch to the end, and pull out the battery towards you until it is completely detached from the
radio.

Installing the Belt
To install the Belt Clip, slide the clip down into the slot on the back of the radio until the Belt Clip-latch clicks. To remove the
Belt Clip, press the Lock-tab down, and then gently pull the belt clip up toward the top of the radio.
External Speaker/Microphone Jack
Each radio can be used with an optional external speaker/microphone or headset, freeing your hands for other tasks. To use
an optional speaker / microphone or headset:
(1) Open the rubber cap on the side of the radio.
(2) Insert the plug(s) into the SPK/MIC jacks.
(3) Place the ear bud into your ear, and adjust the Microphone into your desired position.
Typical 2 pin Kenwood headset configuration
Using a Headset
You can use a headset (#480_5R) for more private communications. To use a headset, lift the rubber cover from over the

headset jack, and then plug in the headset.
Important: Your radio is not submersible or waterproof when using a headset jack. When you remove the headset, be sure
to fully press the jack cover into place to restore its waterproof capability.
Charging the Battery
Charging the Radio
To avoid the risk of personal injury or property damage from fire or electrical shock, only use the accessories specifically
designated for this product. Using the Micro USB Port
Charge the batteries for 6 hours until the battery indicator either stops flashing.
*If you try to transmit while power is low, the radio will automatically turn off.
Basic Operations
Power on/off and volume adjustment
Rotate the Power/Volume knob clockwise to turn the radio on. Rotate the control clockwise /counter-clockwise to adjust the
volume level as you prefer. To turn the radio off, rotate the control counter-clockwise till hearing a mechanical “click”.
Transmission
To communicate, all radios in your group must be set to the same channel. Briefly press the Monitor to enable the Monitor
feature in order to make sure that the frequency is not busy, and then press the PTT key. Release the PTT key to receive. Only
one user at a time can talk during radio communications. Therefore, it is important not to transmit when you are receiving a
communication and use the transmission mode sparingly to allow other users to talk. Transmission consumes a significant
amount of energy and should therefore be used sparingly to prolong the battery life. If you are unable to contact a station
that you have no problems in receiving, the station may be using CTCSS tones or DCS codes.

Monitor
The Monitor feature is for excluding (opening) the Squelch, in order to listen to signals that are too weak to keep the Squelch
permanently opened. Hold down the Monitor to enable such function.
Scan
This function can be activated only by means of the optional programming software. To enable the Scan function, all 16
channels must be programmed. If you turn on the radio on channel 16, the scanning will automatically start. Whenever any
signal is detected, the scanning will stop on a busy channel. If the PTT is pressed, you will transmit on the latest busy channel.
Channel 16 is the priority channel; therefore if you don’t pick up any signal when you press PTT, the radio will transmit on
channel 16.
Squelch
The Squelch function suppresses noises on free channels and allows receiving even weak signals. GT-68 has 10 different
Squelch levels that can be set by programming software: 0 means that the Squelch is turned off; from level 1 to level 9 you
will have different levels of noise reduction. The higher is the level, the louder will be the Squelch. By default, the Squelch
level of GT-68 is set on level 4. Make sure you do not set an
CTCSS/DCS tones
CTCSS and DCS tones are similar to access codes and enable the radio to communicate only with the users that are tuned on
the same channel and have set the same code. For each channel, you can set up to 50 CTCSS tones and 210 DCS codes. The
CTCSS/DCS tones are a sort of “access codes” and enable the radio to communicate only with the other users set on the
same frequency and on the same CTCSS/DCS tone. Undesired signals coming from other stations set on the same
frequency but with different CTCSS/DCS tones won’t be received.
Prompt voice switch settings
The encoder is selected to the 10th channel. Press and hold the PTT and Monitor to turn on the radio, and turn the prompt
voice on or off.
Turn on the prompt voice function, and there will be voice prompts when the encoder is turned on or operated. If you turn

off the prompt voice function, there is only a “beep” prompt when you turn on or operate the encoder.
Emergency alert function
If necessary, you can pre-program the Monitor into the Alarm function via CPS programming software.
Turn on the radio, short press the Monitor to turn on the alarm function. Press the Monitor again to release the emergency
alarm status.
CPS programming path: Edit> Function Setting> Side Key> Alarm
VOX
The VOX feature enables hands free conversations without using PTT: just speak in the direction of the microphone and the
communication will be automatically activated. The VOX sensitivity can be adjusted in 5 different levels (1…5) through the
programming software:
Level 2 is set by default and has the lowest VOX sensitivity, 5 is the lowest one.
With the programming software you can enable/disable the VOX feature and select the sensitivity levels.
Quick operation radio
Without CPS programming software, you can perform the following quick operations through the combination of PTT +
Monitor:
• On channels 1-5, press and hold the PTT + Monitor to turn on the radio and turn the VOX function on or off. The VOX
sensitivity is level 1-5, the level 1 sensitivity is the highest, and the level 5 sensitivity is the lowest. Accompanied by a voice
prompt VOX ON or VOX OFF.
• On the 10th channel, press and hold the PTT + Monitor to turn on the radio and turn on or off the prompt voice function.
• On the 15th channel, press and hold the PTT + Monitor to turn on the radio and switch the prompt language between
Chinese and English.

Move towards other members.
You hear unknown voices or
noise.
You may be interrupted by radios using the same
frequency.
Change the frequency, or adjust the
squelch level.
The radio in analog mode maybe set with no
signaling.
Request your dealer to set signaling for
the current channel to avoid interference
You are unable to hear anyone
because of too much noise and
hiss.
You may be too far away from other members.
Move towards other members.
You may be in an unfavorable position. For
example, your communication may be blocked by
high buildings or blocked in an underground area.
Move to an open and flat area, restart the
radio, and try again.
It may be the result of external disturbance (such as
electromagnetic interference).
Stay away from equipment that may
cause interference.
The radio keeps transmitting.
VOX may be turned on or the headset is not
installed in place
Turn off the VOX function. Check that the
headphones are in place.
You cannot use the keys.
