In the transmitter
, this comprises mainly:
%

In the receiver:
%
Automatic zero setting when switching back on after radio interruption.
%
Locking of the radio commands at relay level in the event of a defective STOP, resp.

To ensure fault-free operation, please follow precisely the following rules for operation:
The unit to be controlled can only be switched on - it is assumed that the transmitter is
ready to operate - when no command unit is actuated. The command necessary to do so
is triggered by the key "ON/HORN". This triggers a horn signal in the unit to be controlled.
After switch-on of the facility to be controlled, this key is used for repeated emission of the
horn signal in accordance with working regulations.
If the NBB radio remote control is not used for a long period, it is urgently recom-
mended - if you use rechargeable batteries - that they should be charged now
and again (about every 4 weeks). This prevents deep discharges of the batteries
and prolongs their useful life. If you shut down the NBB radio remote control for a
long period, we recommend you take the batteries out of the transmitter.
Frequency change:
To change the frequency, keep the "ON/HORN" key pressed down. T h e n o p e r a t e t h e
“FREQUENCY CHANGE" key. If the receiver locks into the new frequency, a horn signal is
given (if present) and the unit to be controlled is ready for operation.
Please observe the particular postal approval regulations of the concerned country.
Channel number:
When changing the frequency the channel number lights up shortly in
the display. During operation the choosen channel can be shown by pressing the
“FREQUENCY CHANGE” key.
