Identifying and conversing with callers

When a caller presses the CALL button on the outdoor unit: 

An electronic door chime sounds DING-DONG and the visual image 

appears on the screen.  (Same to slave monitor (optional)) 

Assuming that your visitor is standing within the range of the camera, you will see the visitor on 
the monitor screen of the indoor unit 

After identifying the visitor you can: 

Talk to the visitor shown on the screen by lifting Handset and have conversation just as 

you would on a normal phone.

Replace the handset.

Pressing the CALL button on the outdoor unit activates the camera for 30 seconds only without 
lifting the handset. However, if you should continue to talk using the handset for longer than 30 
seconds, the camera and monitor screen will be on for 2 minute or longer by pressing monitor 
button. 

Electronic Door Release Option 

If your Video Doorphone System is equipped with the Electronic Door Release option (or has 
been installed for the use of this feature), you can let your caller in simply by pressing the DOOR 
OPEN button. (Only available when monitor screen is on) 

Additional Inter-Phone option 

A supplementary Slave monitor is available as an option to enhance the function of
intercommunication with the main monitor. When a visitor presses the CALL button on the out 
door unit, the electronic chime sounds simultaneously with the main unit. Even during the 
intercommunication with the main unit, you may talk to the visitor at door simply by pressing the 
monitor button

Monitoring visitors

To identify visitors at the door without them being aware that they are being watched or to monitor 
the immediate area around the doorway: 

Press the MONITOR button 

Without lifting the handset, your visitor will now be seen on the screen, but will be unaware of that 
they are being monitored. This particularly useful feature allows you to monitor the visitors at door   
even though they may not have pressed the CALL button and can help to avoid the risk of 
opening the door to strangers.
