3.2 Setting Channels and Digital Codes
To ensure clear communication and prevent interference, each intercom unit must be set to the same digital code and a unique channel if you intend to call specific units, or the same channel for group communication.

- Select Digital Code: On the back of each unit, use the switch to select a digital code (A, B, or C). All units intended to communicate with each other must use the same digital code.
- Set Channel: Long press a channel number key (0-9) on the keypad to set the channel for that station. A short press will call another intercom. It is recommended to set all stations with the same digital code but different channels if you want to call specific users. If you want all units to communicate in a group, set them to the same channel.
- Distribution: Place the intercom units in desired locations. Ensure units are at least 5 meters (approximately 16 feet) apart to avoid interference during initial setup.

4.1 Basic Communication
- TALK: Press and hold the TALK button to speak. Release the button to listen. This is a push-to-talk function.
- CALL: Press the CALL button to send an alert tone to the receiving station. After the tone, press and hold TALK to initiate conversation.
4.2 Advanced Functions
- GROUP: Press the GROUP button to talk with all devices in the intercom system simultaneously. All units set to the same digital code will receive the message.
- VOX (Voice Operated Exchange): Press the VOX button to enable voice-activated transmission. When VOX is active, you can speak without pressing the TALK button, and the other station can reply by pressing TALK. The VOX function activates when sound is detected.
- MONITOR: Press the MONITOR button. This station will continuously monitor its surroundings, and another station can hear the voice from it. This function is useful for monitoring children or elderly individuals. To exit monitor mode, press any key.
