... for multi-channel operation
For multi-channel operation, you can only use the channels in a channel
bank. Each of the channel banks "1" to "8" accommodates factory-preset
frequencies which are intermodulation-free. For alternative frequency
combinations, please refer to the enclosed frequency table. The freely
selectable frequencies can be selected via the "TUNE" menu and can be
stored in the channel bank "U".
When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
For multi-channel applications, use special accessories (see "Accessories"
on page 51).

Care and maintenance

Use a slightly damp cloth to clean the units from time to time.
Note:
Do not use any cleansing agents or solvents.
If you do not use the transmitter or receiver, remove the accupack or the
batteries. After three months at the latest, the accupacks will need a
refresh charge in the L 2015 charger.
If you do not use the transmitter or receiver for extended periods of time
(e.g. while you are on holiday), we recommend storing it in the L 2015
charger which is connected to the mains. This prevents damage to the
accupack due to total discharge.
