However, the distance mayvary according to the surroundings andenvironment. If the system picks up some noisewhile using it within the above mentioneddistance, reduce the distance between thetransmitter unit and the headphones, or select theother channel.Notes•When you use the headphones inside the effectiveareas of the transmitter, the transmitter can be placedin any direction from the listener.• Even within the signal reception area, there are somespots (dead spot) where the RF signal can not bereceived. This is a characteristic inherent to RF signals,and does not indicate malfunction. By slightly movingthe transmitter, location of the dead spot can bechanged.Replacing the ear padsThe ear pads are replaceable. If the ear padsbecome dirty or worn out, replace them asillustrated below.The ear pad is not commercially available. Youcan order replacements from the store where youpurchased this system, or at your nearest Sonydealer.1Remove the old ear pad by pullingit out of the groove on the housing.2Place the new ear pad on the driverunit and insert the edge of the padinto the groove as illustrated.Make sure that the entire edge of the ear pad issecurely inserted into the groove.
