For details, seePairing with a receiver. Using the Wireless Remote Control Function This transmitter is equipped with a wireless remote control function that can be used to set the parameters (low-cut filter, attenuation operation, power save mode, etc.) of the transmitter through the receiver or other devices. This function makes it easier to operate and manage the microphone system while in the field. This wireless control is 2.4 GHz IEEE802.15.4 compliant and has no effect on the RF band of digital wireless audio. This function is activated when pairing is established between the transmitter and the receiver using the RF REMOTE function. Pairing must be done first before the wireless remote control function can be used. Pairing with a receiver Pairing links the transmitter with the receiver which the wireless remote control function is to be used. When the transmitter has been paired with a receiver through the receiver operation, turning on the transmitter while holding down the button establishes the pairing immediately. To carry out pairing through menu operations on the transmitter, do the following. 1 Set the receiver to be used for controlling the transmitter to pairing mode. The following transmitter settings can be done from the wireless remote control:

Group/channel/BAND setting RF transmission power setting Attenuator for the audio input setting Low-cut filter setting Power save setting

+48 V power supply setting For details on menu operation, see Setting Menus. To cancel the wireless remote control function In the RF REMOTE indication, select OFF. Notes on the wireless remote control function The wireless remote control function on the transmitter uses the 2.4-GHz band and may thus be subject to interference from other devices. When pairing fails (Pairing fail is displayed), successful communication between the transmitter and the receiver has not occurred within a given amount of time. Pairing may be harder to do when another receiver is engaged in pairing nearby. When it becomes hard to use the remote control, the remote control may be improved by switching the wireless remote control function off, then on again in the RF REMOTE indication, then re-

pairing with the transmitter (change to a channel with less interference). For details on receiver operations, refer to the operating instructions supplied with the receiver. 2 Press the + or button repeatedly until the RF REMOTE indication is displayed. 3 Hold down the SET button until the item to be set flashes. 4 Press the + or button repeatedly to select PAIRING. 5 Press the SET button to enter.

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 Sony ECM-673/674/678 Electret Condenser 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 lowering the transmission power. To prevent electromagnetic interference from portable communication devices The use of portable telephones and other communication devices near the DWT-P01 may result in malfunction and interference with audio signals. It is recommended that portable communication devices near the DWT-P01 be turned off.
