Notes on Using the
Microphone
• 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 microphone near electrical
equipment (motors, transformers, or
dimmers) may cause it to be affected by
electromagnetic induction. Keep the
microphone as far from such equipment
as possible.
• The presence of the lighting equipment
may produce electrical interference over
the entire frequency range. Position the
microphone so that interference is
minimized.
• To avoid degradation of the signal-to-
noise ratio, do not use the microphone 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 microphone as far from such
equipment as possible or use buffering
material.
On Cleaning
• If the microphone 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 microphone
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 microphone with a dry, soft cloth.
Never use thinner, benzene, alcohol or
any other chemicals, since these may mar
the finish.
Notes on Simultaneous Multi-
Channel Operation
• Keep the microphone at least 30 cm (11
7
/
8
inches) away from another transmitter/
microphone.
When the distances between transmitters
and microphones need to be closer than the
distances above, use a grouping system for
multi-channel systems that include both
digital wireless and analog wireless devices.
For details, refer to “Sony Digital Wireless
Microphone System Frequency Lists” on the
supplied CD-ROM.
• When only digital wireless microphones
are being used, keep the microphone at
least 4 m (13 feet) away from the antenna
of a receiver for up to 10 channels, and at
least 6 m (20 feet) away for 11 or more
channels.
• When a mixture of digital and analog
wireless microphones/transmitters is
being used, keep the microphone at least
6 m (20 feet) away from the antenna of a
receiver.
• This system should be kept at least 100 m
(328 feet) away from any analog wireless
systems using the same frequency when
both are being used in a wide area with no
walls or obstructions.
• If you experience noise, increase the
distance between the microphone and
receiver or decrease the transmission
power on the microphone.
