Recommendations and tips
... for optimum reception
y
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.
y
If, with the twin receiver, reception conditions are unfavourable, you should
use two remote antennas which are connected via antenna cable.
y
To avoid overmodulating the receiver, observe a minimum distance of 5 m
between transmitting and receiving antennas.
y
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
y
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”.
y
When using several transmitters simultaneously, interference can be
avoided by maintaining a minimum distance of 20 cm between two
transmitters.
y
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.
