Important notes on operation

Notes on using the transmitter

•The digital wireless microphone system product must be used within a temperature range of 0°C to 50°C (32°F to 122°F).

•Operating the transmitter near electrical equipment (motors, transformers, or dimmers) may cause it to be affected by electromagnetic induction. Keep the transmitter as far from such equipment as possible.

•The presence of the lighting equipment may produce electrical interference over the entire frequency range. Position the transmitter so that interference is minimized.

•To avoid degradation of the signal-to- noise ratio, do not use the transmitter in noisy places or in locations subject to vibration, such as the following:

-near electrical equipment, such as motors, transformers or dimmers

-near air conditioning equipment or places subject to direct air flow from an air conditioner

-near public address loudspeakers

-where adjacent equipment might knock against the tuner

Keep the transmitter as far from such equipment as possible or use buffering material.

On cleaning

•If the transmitter is used in a very humid or dusty place or in a place subject to an active gas, clean its surface as well as the connectors with a dry, soft cloth soon

after use. Lengthy use of the transmitter in such places or not cleaning it after its use in such places may shorten its life.

•Clean the surface and the connectors of the transmitter with a dry, soft cloth. Never use thinner, benzene, alcohol or any other chemicals, since these may mar the finish.

Notes on simultaneous multi- channel operation

•Keep the transmitter at least 30 centimeters (11 7/8 inches) away from another transmitter.

•When only digital wireless microphones are being used, keep the transmitter at least 4 meters (13 feet) away from the antenna of a receiver for up to 10 channels, and at least 6 meters (20 feet) away for 11 or more channels.

•When a mixture of digital and analog wireless microphones is being used, keep the transmitter at least 6 meters (20 feet) away from the antenna of a receiver.

•This system should be kept at least 100 meters (328 feet) away from any analog wireless systems using the same frequency when both are being used in a wide area with no walls or obstructions.

•If you experience noise, increase the distance between the transmitter and receiver or decrease the transmission power on the transmitter.

Note on microphone and transmitter combinations

It is recommended that you use the ECM- 77BC/9X Sony lavelier microphone with this transmitter. The transmission signal may cause noise on some microphones. If you experience noise, you may be able to reduce it by changing the position of the microphone cable, moving the microphone
