Important Notes on Use / Specifications

• 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 tuner 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 tuner
Keep devices as far from such equipment as possible or
use buffering material.

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.

Design and specifications are subject to change without 
notice.

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.
