Alert signals and temperature reading
•
Under the circumstances of an
unanswered call
from a visitor (e.g. you are away from home
or located at a place which is out of range from the caller unit), the icon (C) will appear on
the screen. This icon is useful to remind you somebody has called. Press the button 8 momentarily
to remove this icon.
•
Under normal back-up operation, the
battery
inside the caller unit (we suggest using good quality
battery such as Duracell) can last for 5-6 months. If the mains power is removed and the caller
unit is used repeatedly, the life of the batteries is reduced and can run flat in 1-2 months. Once
the batteries become run down, the icon (J) or icon (K) appears on the screen and
an alarm will be heard, reminding you to replace with new batteries in the respective caller unit.
Press the button 8 momentarily can stop the alarm but the icon (J) or icon (K) still
remains until new batteries are installed.
•
The outdoor temperature indication provides you with an idea about the weather which is useful
if you plan to go outside of your home. When the system is first installed, the LCD will show the
default setting of - -
°
C. Once the caller unit senses the outdoor temperature, the correct reading
will be shown in the LCD of handset.

When not using the doorphone for a long period of time, remove all batteries from handest and
