Installation of Accessories

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/MlC jacks.
3. Place the ear bud into your ear, and adjust the Microphone into your desired position.

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.

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 Device

Two radios can be charged directly by using the supplied charging cradle. A single radio can charge using the Mini USB port to connect to a USB power source. For fastest charging, turn off the radio before charging.

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 USB Port

1. Connect the included AC adapter with USB connector cable to the radio's USB port. Connect the other end to an outlet that provides USB charging power (NOT to a USB hub).
2. Charge the batteries for 6 hours until the battery indicator either stops flashing.

Using the Charging Cradle

1. Connect the included AC adapter with USB connector cable to the charging cradle's Mini USB port. Connect the other end to a standard AC wall outlet.
2. Set the charging cradle on the desk or tabletop, and place the radio in the charging cradle with the keypad facing forward.
3. Charge the batteries for 6 hours.

Note:

• Use only the supplied batteries, charger, and AC adapter or approved accessories.
• Charge time may vary depending on the battery life remaining.
• The batteries must be installed for the unit to operate, even if the unit is also connected to external power.
• If battery power is low, you cannot operate the radio even using external power. Allow the batteries to charge before using.

*If you try to transmit while power is low, the radio will automatically

Do not charge alkaline batteries. The radio will not be used for a long time, please take out and keep the battery properly.

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 Side key 1 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 Side key 1 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. GT68 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 GT68 is set on level 4. Make sure you do not set an excessively high squelch level because in this case you may not be able to receive weaker signals. On the other hand an excessively low Squelch value could enable the Squelch even when no signals are present. Squelch must always be adjusted when no signals are present. The Time Out timer is settable from 30 sec to 270 sec. only through the programming software. This feature is disabled by default.

CTCSS/DCStones

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 Side Key 1 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 Side Key 1 into the Alarm function via CPS programming software. Turn on the radio, short press the Side Key 1 to turn on the alarm function. Press the Side Key 1 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.
CPS programming path: Edit> VOX >Vox Gain

Quick operation

Without CPS programming software, you can perform the following quick operations through the combination of PTT + Side Key 1:

• On channels 1-5, press and hold the PTT + Side Key 1 key 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 + Side Key 1 to turn on the radio and turn on or off the prompt voice function.
• On the 15th channel, press and hold the PTT + Side Key 1 to turn on the radio and switch the prompt language between Chinese and English.
