7.2. When There is No Sound or the Sound is Disrupted
Sign Possible Cause Measures
The receiver’s reception
indicators are unlit.
The frequency (bank,
channel) settings for the
receiver and the microphone
do not match.
Match the frequency settings for the
receiver and the microphone.
The receiver is in the
Channel Scan or Spectrum
Scan mode.
Check the front panel of the receiver, and
cancel the current mode if it is different from
what is normally displayed.
(Description of each function on p. 11 ,
p. 24 .)
The batteries of the
microphone are running low.
If they are rechargeable batteries, recharge
them.
If they are dry batteries, replace them with
new batteries.
The signal level meter’s
level is low even though
the distance between the
microphone and the antenna
is adequate.
The antenna’s attenuator is
not set correctly.
Change the attenuator to the correct
setting. (See Antenna instruction manual.)
The receiver’s reception
indicators light red.
The Encryption setting or
the code setting does not
match even though the
banks and channels of
the microphone and the
receiver are set to match.
All the settings must be matching.
There is interference that
has the same frequency as
the microphone.
Change the channel.
Note
See the Channel Scan function ( p. 11 )
about available channels, and see the
Spectrum Scan function ( p. 24 ) for
interference.
If the level of interference is weaker than
the microphone signal, it may be possible
to prevent interference by turning on the
antenna’s attenuator.
However, this will narrow the usage area.
Signs other than those
mentioned above.
The distance between
the microphone and the
antenna is too close.
Be sure to turn on the antenna’s attenuator,
or to have at least a 3-meter space
between the microphone and the antenna.
The speaker and amplifier
are connected incorrectly.
Connect them correctly.
Note
See the receiver and antenna instruction manuals for detailed information.
