approx. 5 m. It can be affected by
external influences. The hazard
warning flashers confirm operation.
Handle with care, protect it from
moisture and high temperatures and
avoid unnecessary operation.

be operated with the remote control,
it may be due to the following:
● The range is exceeded.
● The battery voltage is too low.
● Frequent, repeated operation of the remote control while not in
range, which will require
reprogramming by a workshop.
● 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.
