Important Notes on
Operation
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.
Network security
Depending on the operating environment, unauthorized
third parties on the network may be able to access the unit.
When connecting the unit to the network, be sure to
confirm that the network is protected securely. SONY
WILL NOT BE LIABLE FOR DAMAGES OR DATA
LEAKS OF ANY KIND RESULTING FROM
UNAUTHORIZED THIRD-PARTY ACCESS OR
SECURITY PROBLEMS OF ANY KIND.

Notes on Using the Receiver

• The digital wireless microphone system product must
be used within a temperature range of 0 °C to 50 °C
(32 °F to 122 °F).
• Operating the receiver near electrical equipment
(motors, transformers, or dimmers) may cause it to be
affected by electromagnetic induction. Keep the
receiver as far from such equipment as possible.
• The presence of lighting equipment may produce
electrical interference over the entire frequency range.
Position the antenna and wireless microphone so that
interference is minimized.
• To avoid degradation of the signal-to-noise ratio, do not
use the receiver 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 public address loudspeakers
– where adjacent equipment might knock against the
tuner
Keep the receiver as far from such equipment as
possible or use buffering material.

Cleaning

• If the receiver is used in a very humid or dusty place or
in a place subject to an active gas, clean its surface as
well as the connectors with a dry, soft cloth soon after
use. Lengthy use of the receiver in such places or not
cleaning it after its use in such places may shorten its
life.
• Clean the surface and the connectors of the receiver
with a dry, soft cloth. Never use thinner, benzene,
alcohol or any other chemicals, since these may mar the
finish.

Audio degradation due to weak
reception
In a digital wireless system, sound quality is maintained
up to the maximum transmission range. Beyond this
point, as the radio wave becomes weaker, data
synchronization is lost and the connection finally breaks.
Sony digital wireless systems suppress the occurrence of
large noise between these two points as the signal
weakens. As a result, digital processing is conducted in a
way that allows the signal to degrade in a very natural
way.
To prevent electromagnetic interference from
portable communication devices
The use of portable telephones and other communication
devices near the unit may result in malfunction and
interference with audio signals. It is recommended that
portable communication devices near the unit be turned
off.
