is confirmed by the motor’s emergency light blinking
twice (can take 20 seconds).
The internal meter readings for the individual motors
have now been reset to ‘0’ and the sync function can
work correctly again.
Use of the emergency lowering button consumes a
great deal of battery power, which means you will need
to replace the batteries.

being switched on and all components being con-
nected properly
Disconnect the mains supply unit from the mains out-
let. Wait a minute and then reconnect it. If necessary,
connect a bedside lamp to check that mains voltage
(240V) is present. If there is no current, check the fuse.
Press the “all motors down” button
(6)
to reset all ad-
justments. The control of the _75RF / _75RF bridge®
contains microprocessors, so irregular power supply
can lead to malfunctions.
