Fault
If the central locking system cannot
be operated with the radio remote
control, it may be due to the following:
● Range is exceeded.
● Battery voltage is too low.
● Frequent, repeated operation of the radio remote control while not
in range, which will require re-
synchronisation.
● Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
