EXIT

Select this parameter to exit from the menu, short touch the menu key (11)

to confirm. Alternatively, in case no key is being touched within a period of 10

sec, the menu will exit from the screen (18) automatically.

To return to standby mode and switch off the screen (18), short press the

power/hang up button (15). Alternatively, if no key is being touched for

over 1 min, the handset will return to standby mode automatically.

During conversation and when the menu is not shown on the screen (18), the

sound volume heard through the speaker (19) can also be adjusted using the

left/right key (9) (10) and the corresponding volume bar graph is shown on

the screen (18). Please note the loudness of the door chime is fixed and

cannot be adjusted.

Make sure there is power supplied to the caller unit (by either 12V DC or

alkaline batteries). Now press the Call button (1), a ding-dong tone will be

heard. Until a handset answers the call, the ding-dong tone will be heard

periodically, reminding the visitor to keep waiting. In case there is no answer

after 30 seconds, the caller unit ends the call by itself. Press the Call button

(1) to initiate the call again.

N.B. In case there are two caller units (frontgate and backgate), only the unit

whose call button (1) is first pressed will send out a call signal to handset,

the remaining unit will be kept in standby mode until the conversation is over.

If its call button (1) is pressed during this period, a two “Be-Be” sound will

be heard, indicating the unit is under hold mode.

Once the call is being answered, the ding-dong tone stops ringing.

Conversation can now be conducted by speaking into the microphone (2).

Upon receiving a call, the screen (18) will show the

image of the visitor, but audio communication with the

visitor will not be initiated unless the call is answered by

a short press of the Talk/answer button / (16).

Once the Talk/answer button / (16) is pressed,

conversation is now possible and the voice of the visitor

can be heard from the speaker (19). To talk back to the

visitor, press and hold the Talk/answer button /

(16) and speak towards the microphone (17) once you

see the text “TALK BACK” appear at the lower right corner of the screen (18)

(If you speak before seeing the text, then it is possible that the visitor may

NOT be able to hear some of your first spoken words.).

Release the Talk/answer button / (16) after you finished speaking to

listen to the visitor. It should be worth noted that the voice of the visitor

cannot be heard while pressing the Talk/answer button / (16). Upon
