5. Operating Instructions
5.1 Power On/Off and Volume
To power on the radio, rotate the Volume/Power knob clockwise until you hear a click. Continue rotating to increase volume. Rotate counter-clockwise to decrease volume and turn off the radio.
5.2 Channel and Frequency Selection
The GT-3TP Mark III supports both Frequency Mode (VFO) for direct frequency input and Channel Mode (MR) for pre-programmed channels.
- Press the VFO/MR button to switch between modes.
- In VFO mode, use the numeric keypad to enter desired frequencies (e.g., 145.000 MHz or 440.000 MHz).
- In MR mode, use the UP/DOWN arrow keys or the numeric keypad to select a stored channel (1-128).
- Press the BAND button to toggle between VHF (144-148MHz) and UHF (420-450MHz) bands.
5.3 Transmit Power Settings
The radio offers multiple power output levels to conserve battery life or maximize range:
- Low Power: For short-range communication and extended battery life.
- Mid Power: A balanced option for moderate distances.
- High Power (8W): For maximum range and clarity, especially over long distances up to 11km.
To adjust transmit power, navigate through the menu options. The display will indicate the current power setting (TXP HIGH, TXP MID, TXP LOW).

5.4 VOX Function (Voice Operated Transmission)
The VOX function allows for hands-free transmission. When activated, the radio will automatically transmit when it detects your voice, eliminating the need to press the PTT button.
- Access the VOX setting through the radio's menu.
- Adjust the VOX sensitivity level to prevent accidental transmissions or missed voice activation.
5.5 CTCSS/DCS Tones
The radio supports 50 CTCSS (Continuous Tone-Coded Squelch System) and 104 DCS (Digital-Coded Squelch) tones. These tones help filter out unwanted signals and provide group calling convenience by allowing you to hear only transmissions from radios set to the same tone.
- Configure CTCSS/DCS tones in the menu for both transmit (TX) and receive (RX) frequencies.
5.6 Frequency Offset (OFFSET)
The OFFSET function is used for repeater access. It sets the difference between the transmit and receive frequencies when communicating through a repeater.
- Set the offset direction (positive or negative) and the offset frequency value in the menu.
5.7 Busy Channel Lockout (BCLO)
BCLO prevents the radio from transmitting on a channel that is already in use, avoiding interference with ongoing conversations.
- Enable or disable BCLO in the radio's menu settings.
