Note
1. Different intercom units should be set different code numbers.
2. In general, there is no need to set the channel. You will only need to modify it if you receive a call from an unknown caller. When modifying your
system’s channel, all units need to be modified to the same channel number.
3. Additionally, the intercom device will easily receive interference from various wireless signals. Please keep your intercom away from bluetooth
speakers, microwave ovens, radios, and other equipment. Otherwise, your intercom may experience static.
4. This intercom system is expandable for up to 10 units in one system. We do not recommend connecting more than 10 units to a single system.
5. To avoid the volume is too low to hear,please keep a distance of 20-30 cm away from the microphone when you talk with each other.
