How to ring the doorbell of building number and unit number

As long as visitors enter the room number, they can call the residents to unlock the door. For example, you need to call the owner of 1 unit 10 1, enter 010/on the outdoor keyboard, and then press the unlock key to unlock the door. If it is wrong, please press the # key to reset and re-enter the room number.

Second, the use of indoor machines.

1. When you hear the bell, pick up the phone and press Connect to install it next to the indoor unit, so you can hear the voice of visitors from the indoor unit. The indoor unit with visual doorbell function can also see the image of the visitor, thus confirming whether the following people know each other.

2. After confirming the identity of the visitor, press the unlock button to open the door. If you hang up the indoor unit, you can end the call without opening the door.

After hanging up the indoor unit, you need to put the microphone of the indoor unit on the take-up switch, otherwise the next visitor will not be able to talk. Of course, some indoor machines don't have microphones now, so don't worry.

Three. Use of other functions

1. If there is an accident, press the alarm button of the indoor unit, and the indoor unit will give out a continuous alarm sound, which can attract the attention of neighbors.

2. The video contrast and brightness of the indoor unit need not be set. Generally, it has been debugged before leaving the factory, and the ringtone can be changed according to the user's preferences.
