be operated with the radio remote
control, it may be due to the following:
■ The range is exceeded.
■ The 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.
