The intercom system is a real-time communication system which has no memory or storage function. Because of this, you cannot receive any information while you are talking with others. Additionally, you cannot speak to another user if they are speaking at the same time.

Please note that you will need to set the same channel and code if you want 2 intercom stations to receive communication. It also means any other intercoms can also communicate if they have same channel code.

For example, your neighbors may be able to interfere with your intercom system. We suggest setting another channel or code to avoid interference.

A tip for setting your home intercom system. For example, let's say you have a 4 station intercom system for your home for different rooms. You can set all 4 stations with the same code A(code A, B or C are choices), then you set different channels for all 4 stations. If your system receives interference, you can change it to another code for all of your stations without changing every station's channel making this a very convenient option.

We sincerely suggest that you can read User Manual before you use our intercom system. The arrival time depends on some factors and different areas.
