Sennheiser ew500 manual Care and maintenance, For the EK 500 receiver, For optimum reception

... for the EK 500 receiver

The antenna should hang freely and be at least 1 cm away from the body. The antenna must not be in direct contact with the skin. If the receiver is mounted onto a camera, we recommend using the A 17 helical antenna.

... 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 EM 500 receiver, reception conditions are unfavourable, you should use two remote antennas which are connected via antenna cable (see “Accessories”).

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

You cannot use all adjustable frequency combinations simultaneously. The factory-preset frequencies (presets), however, are intermodulation-free. If you wish to program new frequency combinations, please contact your local Sennheiser agent who will provide you with information on the correct frequency choice.

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”).
