Important Notes on Use
The operating range of the 2.4 GHz band used by the units
may be reduced and noise may occur due to interference
from the operating environment or from other wireless
stations. In such cases, moving the units away from other
wireless stations or changing the channel may resolve the
problem.
• If other wireless stations are being used nearby,
distance the units from the stations as much as possible,
or change the channel or RF mode being used.
• If this does not resolve the problem, try turning off the
other wireless stations (i.e., stopping their radio signals)
one by one.
• If microphones other than those supplied or other than
the ECM-HZ1UBMP/LZ1UBMP are connected,
problems such as lack of sound and phase inversion
may occur.
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.
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.
Notes on Charging
Batteries
• Always use the BC-DWZ1 battery charger (not
supplied) when recharging.
• Only nickel-metal-hydride batteries can be recharged.
• The unit will automatically turn off during recharging.
Audio cannot be transmitted during this time.
• When charging batteries, follow the temperature
specifications for the batteries you are using.
• Do not insert batteries that were used in other devices in
the transmitter for charging.
Important
The antenna covers (ZTX-M02RC) and the body of the
unit (ZTX-B02RC) are the areas that are charged and may
become hot during or immediately after charging. This is
not a malfunction.
Caution
To prevent electromagnetic interference from portable
communication devices
The use of portable telephones and other communication
devices near the DWZ series components may result in
malfunction and interference with audio signals. It is
recommended that portable communication devices near
the DWZ series components be turned off.
