Radio remote control
Used to operate: ● central locking system
● anti-theft locking system
● anti-theft alarm system
● soft top
● power windows
The radio remote control has a range of approx. 20 metres. It can be
restricted by external influences. The
hazard warning flashers confirm
operation.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
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.
