Important Notes on Use

The use of some frequency bands may be restricted by
law, depending on the country or region. Check in
advance before use.
The NFC communication function is used only for
communication between a transmitter and a tuner. It
cannot be used for communication with other devices.
Notes
• Always verify that the unit is operating properly
before use. SONY WILL NOT BE LIABLE FOR
DAMAGES OF ANY KIND INCLUDING, BUT
NOT LIMITED TO, COMPENSATION OR
REIMBURSEMENT ON ACCOUNT OF THE
LOSS OF PRESENT OR PROSPECTIVE PROFITS
DUE TO FAILURE OF THIS UNIT, EITHER
DURING THE WARRANTY PERIOD OR AFTER
EXPIRATION OF THE WARRANTY, OR FOR
ANY OTHER REASON WHATSOEVER.
• SONY WILL NOT BE LIABLE FOR CLAIMS OF
ANY KIND MADE BY USERS OF THIS UNIT OR
MADE BY THIRD PARTIES.
• SONY WILL NOT BE LIABLE FOR THE
TERMINATION OR DISCONTINUATION OF
ANY SERVICES RELATED TO THIS UNIT THAT
MAY RESULT DUE TO CIRCUMSTANCES OF
ANY KIND.
Condensation
If the unit is suddenly taken from a cold to a warm
location, or if ambient temperature suddenly rises,
moisture may form on the outer surface of the unit and/or
inside of the unit. This is known as condensation. If
condensation occurs, turn off the unit and wait until the
condensation clears before operating the unit. Operating
the unit while condensation is present may damage the
unit.
OLED panel
Due to the characteristics of the material used in the
OLED panel, permanent burn-in or reduction in
brightness may occur.
These problems are not a malfunction.
Consumable parts
The life expectancy of the electrolytic capacitor is about
5 years under normal operating temperatures and normal
usage (8 hours per day; 25 days per month). If usage
exceeds the above normal usage frequency, the life
expectancy may be reduced correspondingly.

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 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.

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.
