Maintenance
Regularly control the technical safety of the door/window alarm with numerical
code for damages of the line and the housing.
If there is reason to believe that safe operation has become impossible put
the unit out of operation and secure it against any unintended operation.
Remove the batteries from the housing!
Safe operation must be presumed to be no longer possible, if:
- the door/window alarm with numerical code shows visible damages
- the doow/window alarm with numerical code does not function any more
- after storage under unfavourable conditions for a long period of time or
- device was exposed to extraordinary stress caused by transport
Observe the following instructions before cleaning the door/window alarm
with numerical code or performing maintenance work:
When opening covers or removing parts you may expose
live parts.
Therefore, disconnect the device from all voltage
sources before performing maintenance work or repairs.
Capacitors inside the device may still carry voltage
even though they have been disconnected from all
voltage sources.
