User manual

Whenever the handset is located at a spot which is

outside the communication range of the caller unit

(either front or back gate or both), an alarm will be heard

and the screen (18) will show the following:

Such alarm cannot be immediate and will alert you only

when you are out of range for over 2 minutes (when 12V

DC supply is available or 20 minutes if a battery is

used). Once the handset falls back in range, the alarm

will stop automatically. A short press of the power/hang

up button (15) can cut off the alarm sound but the

“out of range” text will continue flashing on the screen (18) until the handset

falls within the range of the caller unit.

N.B. This out of range alert will also occur in case the batteries of the caller

unit run down and its DC power is cut off.

When the Light sensor (5) detects a low light intensity, once the call button

(1) is pressed, the white illumination LED (4) will light up automatically to

illuminate the face of the visitor. This is subjected to “AUTO” being selected

for the GATE LIGHT function menu.

A beep sound will be heard whenever a key is being touched to validate your

entry. To eliminate such a beep sound, long touch the left key (9) until a

second beep is heard. To resume the beep sound, long touch the right (10)

key until a beep sound is heard.
