Troubleshooting

1. Intercoms Not Connecting

If your intercoms are not connecting or experiencing issues, you may need to clear the pairing settings and re-pair them.

Clearing Pairing Settings:

On each intercom unit, press and hold both the VOL+ and power buttons simultaneously for 5 seconds until you hear a "Di" sound. This indicates the pairing settings have been cleared. Repeat this process for both intercoms to ensure a clean slate for the next pairing attempt.

Refer to the video above for a visual guide on clearing pairing settings.

2. Limited Range

While the intercoms offer a long range, environmental factors such as thick walls, multiple floors, or electronic interference can reduce effective communication distance. For optimal performance, try to minimize obstructions between units.

3. Audio Quality Issues

Ensure the volume is set appropriately using the VOL- and VOL+ buttons. If static or unclear audio persists, try moving closer to the other unit or away from potential sources of interference.
