5. Operating Instructions
5.1 Selecting a Channel
Your walkie talkies have 22 available channels. Both units must be on the same channel to communicate.
- Press the Menu button once. The channel number on the screen will flash.
- Use the Up or Down buttons to select your desired channel (1-22).
- Press the PTT button to confirm your selection and exit the menu, or press Menu again to move to sub-channel settings.

5.2 Using Sub-Channels (CTCSS/DCS)
Sub-channels (Continuous Tone-Coded Squelch System / Digitally Coded Squelch) allow for private communication by filtering out unwanted transmissions on the same main channel. Both units must have the same main channel and sub-channel settings.
- After selecting your main channel (as described above), press the Menu button again. The sub-channel number will flash.
- Use the Up or Down buttons to select your desired sub-channel (1-99).
- Press the PTT button to confirm your selection.
5.3 Transmitting (Push-to-Talk - PTT)
- To transmit: Press and hold the PTT button located on the side of the walkie talkie. Speak clearly into the microphone.
- To receive: Release the PTT button.
5.4 Voice Activated Transmission (VOX)
The VOX feature allows for hands-free communication. When activated, the walkie talkie will automatically transmit when it detects your voice.
- Press the Menu button multiple times until the VOX icon appears on the screen.
- Use the Up or Down buttons to select a VOX sensitivity level (e.g., 1-3, with 3 being most sensitive). To disable VOX, select 'OFF'.
- Press the PTT button to confirm.
5.5 Using the Flashlight
The built-in flashlight provides convenient illumination.
- To turn on/off: Press the Flashlight button (often shared with Scan/Monitor).

5.6 Sending a Call Tone
- To send a call tone: Briefly press the Call Tone button (often shared with Keypad Lock). This sends an audible alert to other walkie talkies on the same channel.

The keypad lock prevents accidental button presses.
- To lock/unlock: Press and hold the Call Tone / Keypad Lock button until the lock icon appears/disappears on the screen.
5.8 Adjusting Volume
