... for multi-channel operation
y 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 c an be
stored in the channel bank “U”.
y When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
y For multi-channel applications, use special accessories (see “Accessories”
on page 51).
Care and maintenance
y Use a slightly damp cloth to clean the units from time to time.
Note:
Do not use any cleansing agents or solvents.
y 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.
