Recommendations and tips

. for the EK 300 IEM G2 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. 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 SR 300 IEM G2 transmitter or the SR 350 IEM G2 twin receiver, transmission conditions are unfavourable, you should use a remote antenna which is 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 the transmitting 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 in a channel bank. Each of the channel banks 1 to 8 accommodates up to 12 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. For multi-channel applications, use the appropriate transmitter combiners (see Accessories and spare parts on page 40): SR 300 IEM G2 stereo transmitter: AC 2 transmitter combiner SR 350 IEM G2 twin transmitter: AC 2 transmitter combiner (only when the transmission power is set to LOW) or AC 3200 transmitter combiner

Care and maintenance

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