Important Notes on
Operation
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.
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 connection away from the
antenna, or lowering the transmission power.
To prevent electromagnetic interference from portable
communication devices
The use of portable telephones and other communication
devices near the DWT-B01N may result in malfunction and
interference with audio signals. It is recommended that
portable communication devices near the DWT-B01N be
turned off.
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
• The following distances should be kept between any two
transmitters.
- When using U14 models:
1 m (3.3 feet) or more
- When using models other than U14:
30 cm (11 7/8 inches) or more
When the distances between transmitters 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.
