Setting Receiver Channel 2 (applies to Speaker DS-20 only)
In most European countries, channels 1, 2 and 3 are free channels that
do not require a licence.
Under Increased range more channels can be selected. These channels,
however, often require licences; see Radio range and channels .
When the FFC box is ticked, the colour green indicates which channels
have a low noise level and are suitable for use in the current environment.
Check that no transmitters in the system are started when using FFC.
