Important Notes On Use; Usage And Storage; Cleaning - Sony DWZ-M50 Operating Instructions Manual

Important Notes
on Use
The 2.4 GHz band used by the units is also
used by other devices, such as microwave
ovens, wireless LAN devices, and mobile
terminals.
Interference from such wireless devices
using the 2.4 GHz band may reduce the
operating range of the units and cause noise
to occur.
• Use the Best Channel Selection or Clear
Channel Scan function to select channels
with the least interference.
• If the reception status is poor, move the
microwave oven, wireless LAN device,
mobile terminal, or other devices using
the 2.4 GHz band at least 10 m away
from the units, or change the RF mode of
the units.
• If this does not resolve the problem, stop
operation of the other wireless devices
using the 2.4 GHz band (i.e., stop their
radio signals).
• The frequencies assigned to each channel
of a 2.4 GHz band wireless microphone
system other than the Sony DWZ series
may differ and may not be compatible.
Therefore, simultaneous use with such
systems may not be possible.
Precautions for installation
• To prevent audio noise caused by
interference from other transmitters or by
excessive RF inputs, maintain a distance
of at least 30 cm between the transmitter
and the receiver.
• Install the antenna of the receiver as far
away from metallic objects as possible.
• When using the units with a guitar, noise
may occur depending on the type of
pickup used. If noise occurs, place the
transmitter at least 30 cm away from the
32

pickup portion of the guitar. Changing
the cable paths may also reduce the noise
levels.
Precautions for use with
microphones
• If microphones other than the ECM-
GZ1UBMP (supplied with the
DWZ-B50I) or other than the ECM-
HZ1UBMP/LZ1UBMP (supplied with
the DWZ-M70HL) are connected,
problems such as lack of sound and phase
inversion may occur.
• Attaching a microphone unit from
another manufacturer onto the ZTX-M01
handheld microphone may result in RFI
or EMF noise.

Usage and Storage

• Operating the DWZ series components
near electrical equipment (motors,
transformers, or dimmers) may cause it to
be affected by electromagnetic induction.
Keep the DWZ series components as far
from such equipment as possible.
• The presence of the lighting equipment
may produce electrical interference over
the entire frequency range. Position the
DWZ series components so that
interference is minimized.

Cleaning

Clean the surface and the connectors of the
DWZ series components with a dry, soft
cloth. Never use thinner, benzene, alcohol
or any other chemicals, since these may mar
the finish.
