Marmitek DOORPHONE 210 Manual Del Usario página 16

To avoid misuse by children, this door lock opening
function can be activated or deactivated. When
deactivated, touching the key (13) will have no effect
and the text "KEY DEACTIVATED" will show on the
screen (18) for 2-3 sec.
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.
