Sony URX-S03D, Operating Instructions Manual

Important Notes on Use

Usage and Storage

• Operating the UWP-D series devices near electrical 

equipment (motors, transformers, or dimmers) may 
cause interference due to electromagnetic induction. 
Keep the devices as far from such equipment as 
possible.

• The presence of lighting equipment may produce 

electrical interference over a wide frequency range. In 
this case, interference may fluctuate with the position of 
the receiver antenna and position of the transmitter. 
Position the devices so that interference is minimized.

• To avoid degradation of the signal to noise ratio, do not 

use UWP-D devices 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 PA (public address) loudspeakers
– Near equipment that might knock against the receiver
Keep devices as far from such equipment as possible or 
use buffering material.

Cleaning

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

To prevent electromagnetic interference

Some channels may be unable to be used due to noise 
generated due to the effects of external noise and/or 
radio interference. In this case, it is recommended to 
stop transmitting (turn the power off) or change to 
another frequency (change channel).

To prevent electromagnetic interference from 
portable communication devices

The use of portable telephones and other 
communication devices near the devices may result in 
malfunction and interference with audio signals. It is 
recommended that portable communication equipment 
near the devices be turned off.
