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
/
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
