9.3.3 Adjusting the background
lighting and standby
You can adjust the brightness of the background to your specific lighting
conditions. You can also select how many minutes after the last press of a
button the central transmitters goes into sleep mode to save energy.
NOTE
If you set the brightness to a low value (e.g. 50%), the central transmitter runs
considerably longer before the batteries need to be replaced. When the cen-
tral transmitter is supplied via the charging station, it always remains active.
Sleep mode only becomes active if rechargeable batteries are being used
and after the set time period elapses.
