Where to place the transmitter Placing it up off the floor, such as on a desk, is recommended. Notes • Do not place the transmitter on or near the following objects. Doing so may cause noise. - Main unit, TV, speaker, fluorescent lamp, floor. - Radio waves generated such as cell phones and cordless phone systems or metal instruments are placed on the unit. - Inside a building with walls containing steel beams. - Area with many steel file cabinets, etc. - Area with many electrical appliances capable of generating electromagnetic noise. - Area facing roadways. - Radio transceivers in trucks, etc. - Wireless communication systems installed along roadways. • Even within the signal reception area, there are some spots (dead spot) where the RF signal cannot be received. This is a characteristic inherent to RF signals, and does not indicate a malfunction. By slightly moving the transmitter, the location of the dead spot can be changed. Hooking up the transmitter (European model only) You can use the wireless stereo headphone system (MDR-RF820RK) as a transmitter by hooking it up to an optional component. For details on how to hook up and place this system, refer to the operating instructions of the MDR-RF820RK. To listen to audio using this system, see "Listening to audio using the wireless system" on page 25. Notes • To use the MDR-RF820RK as a wireless stereo headphone system, use the connecting cord to plug the headphone system into the PHONES jack of the main unit. For details, refer to the operating instructions of the MDR-RF820RK. • Turn down the volume on the main unit before charging the batteries. When placing the wireless headphones on the transmitter to charge the headphone batteries, RF signals are not sent from the transmitter and noise may be output. • The optimum distance between the transmitter unit and the main unit is shorter than the distance between the transmitter unit and the wireless headphones. Listening to audio using the wireless system 1 Start playing the connected component. 2 Press FUNCTION repeatedly to switch the function to WIRELESS. (European model only) Change the color of the CHG indicator on the transmitter unit from green to red (or remove the wireless headphones from the transmitter). 3 Press +/- (or TUNING +/- on the unit). "AUTO SCAN" appears. If the system picks up some noise or "AUTO SCAN" does not disappear • Reduce the distance between the transmitter unit and the main unit. • Select another channel using CHANNEL 1-3 on the transmitter, then press +/- (or TUNING +/- on the unit). "AUTO SCAN" appears. Notes • You may not hear the beginning of the sound from the main unit until the transmitter starts sending the RF signals after detecting an audio signal. • If the transmitter is connected to the headphones jack of the source component, set the volume of that component as high as possible without distorting the audio signal. • If you hold the antenna of the transmitter with your hand, noise may occur. However this is not a malfunction. • When the transmitter is not to be used for a long period of time, disconnect the AC power adaptor from the wall outlet holding the plug. Do not pull on the cord. 25GB Optional Components
