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.

yIf, with the twin receiver, reception conditions are unfavourable, you should use two remote antennas which are connected via antenna cable.

yTo avoid overmodulating the receiver, observe a minimum distance of 5 m between transmitting and receiving antennas.

yObserve a minimum distance of 50 cm between receiving antennas and metal objects (such as cross members or reinforced-concrete walls).

... for multi-channel operation

yFor 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”.

yWhen using several transmitters simultaneously, interference can be avoided by maintaining a minimum distance of 20 cm between two transmitters.

yUse 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.
