3.5 Remote control cable
(option)
The remote control box can be connected to the electronic box by means of a
remote control cable.
Please note! The cable is not delivered together with the IRC-system as
standard.
The remote control cable can be used if the remote control box cannot
communicate with the electronic box in case of battery failure, interruption in the
radio communication, errors in radio transmitter/receiver, or the like,
The cable has an adapter in one end, which is inserted in the battery
compartment on the remote control box.
3.6 Transmitter System, Frequencies
Every time the IRC-system is started up, one out of 16 frequencies in the ISM-
band is chosen.
In the self-test phase during start up of the remote control box, the system is
testing whether the chosen frequency can be used or whether it collides with
other radio transmitters. If it cannot be used, repeat the starting up procedure
and the next frequency will be chosen.
A coded data telegram is now transmitted from the remote control box with an
address that must be in accordance with a corresponding data telegram with its
address in the electronic box at the frequency in question.
When the radio receiver has accepted the coded data telegram of the radio
transmitter, the IRC-system is ready for operation.
