Recommendations and tips

... for optimum reception
Transmission range depends to a large extent on location and can vary
from about 10 m to about 150 m. There should be a "free line of sight"
between transmitting and receiving antennas.
If, with the twin receiver, reception conditions are unfavourable, you should
use two remote antennas which are connected via antenna cable.
To avoid overmodulating the receiver, observe a minimum distance of 5 m
between transmitting and receiving antennas.
Observe a minimum distance of 50 cm between receiving antennas and
metal objects (such as cross members or reinforced-concrete walls).
... for multi-channel operation
For multi-channel operation, you can only use the channels within a channel
bank. Each of the channel banks "1" to "8" accommodates up to 20
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.
Use special accessories for multi-channel applications (see "Accessories" on
page 69).

Care and maintenance

Use a slightly damp cloth to clean the twin receiver from time to time.
Note:
Do not use any cleansing agents or solvents.
