Starting the receiver
To start the receiver, just press one of the buttons on the navigation pad. The receiver will now display for a
short time the firmware version number and then the last selected channel number. The back light of the

display shows the selected channel. During the channel selection the audio signal will be muted.
If the buttons are held down when pressed, you can scroll through the channels more quickly.
The display shows the selected channel.
When switched off the last selected channel will be stored and the receiver will
default to that channel when switched on again.
Channel display
In case of using Shift Mode with a 32-channel receiver, the channel display
can switch up to channel 38; however the IR- transmission is supported up
to channel 31. This means that the maximum number of channels that can
be used in Shift mode will be 25 (OR+24). Shift mode is a channel offset by a
factor of 7 and is selected when interference is experienced with switched energy
saving lamps. In case of interference the disturbances are audible up to channel 5
or 6. The interference comes from the first, second, and third harmonic of the
lighting system. Adjustment to Shift mode – if required - will be made by the
installing company or from an authorised technician.
