Precautions
This wireless microphone system uses FM radio
waves for transmission. Therefore, there may be cases
where the transmission of the sound may be hindered
when the system is used near certain obstacles. FM
radio waves may also be deflected by walls, etc.
Under such circumstances, the sound may be
intermittent or distorted at times. However, these are
the characteristics of FM radio waves and this does
not indicate a malfunction.
* The system should never be dropped or subjected to
extreme shock.
,
° Keep the system away from extremely high
temperatures (above 140° F or 60° C) and humidity.
* Do not use this system in the following locations as
doing so can cause microphonics (electrical
disturbance noise) which will impair the
performance of this system.
—A very noisy (more than 70 phone) location.
—A location with a lot of vibration.
—A location near a rotating machine or a
transformer.
— Near a speaker of a PA system.
—Near recording studio equipment.
You do not need to have a license to operate this
microphone system. However, observe the
following points.
— Avoid using the system near a broadcasting
station, airport or inside an airplane.
—If radio interference from other radio equipment
occurs, alter the radio channel or change the
location. (You are not protected by law against
any radio interference caused by other radio
equipment .)
¢ When this system is connected to a radio cassette
player, etc. and the system's lavalier microphone is
placed too close to the speaker of the radio cassette
player, acoustic feedback (a howling effect) may
occur.
If this happens, change the direction of the
microphone until the howling stops, or decrease the
volume of the radio cassette player.
When using the system outdoors, avoid getting the
system wet.
Should any liquid fall onto the system, wipe it
thoroughly with a dry soft cloth.
The system is a monaural type.
Therefore, if you use this system with equipment
capable of stereo recording, the recorded sound will
become monaural.
