Notes on using the
transmitter
• 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 transmitter near electrical
equipment (motors, transformers, or
dimmers) may cause it to be affected by
electromagnetic induction. Keep the
transmitter as far from such equipment as
possible.
• The presence of the lighting equipment
may produce electrical interference over
the entire frequency range. Position the
transmitter so that interference is
minimized.
• To avoid degradation of the signal-to-
noise ratio, do not use the transmitter 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 transmitter as far from such
equipment as possible or use buffering
material.
On cleaning
• If the transmitter 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 transmitter
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 transmitter 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 transmitter at least 30
centimeters (11
7
/
8
inches) away from
another transmitter.
• When only digital wireless microphones
are being used, keep the transmitter at
least 4 meters (13 feet) away from the
antenna of a receiver for up to 10
channels, and at least 6 meters (20 feet)
away for 11 or more channels.
• When a mixture of digital and analog
wireless microphones is being used, keep
the transmitter at least 6 meters (20 feet)
away from the antenna of a receiver.
• This system should be kept at least 100
meters (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 transmitter and
receiver or decrease the transmission
power on the transmitter.
Note on microphone and
transmitter combinations
It is recommended that you use the ECM-
77BC/9X Sony lavelier microphone with
this transmitter. The transmission signal
may cause noise on some microphones. If
you experience noise, you may be able to
reduce it by changing the position of the
microphone cable, moving the microphone
