that REDCAT is powered on

when speaking into the microphone.
the REDCAT channel A & B
volume controls are set to just
below mid-range.
Resolution
check power connections between the wall
and both ends of the power adapter and at
the back of the REDCAT. 24VDC 1.75A.
Verify that the frequency of the microphone
matches the frequency of the REDCAT (White
microphone = 2.06/2.54; Black microphone =
3.2/3.7).
If volume control knobs are recessed, press
each once to extend them for adjustment.
Test
the original microphone with
another REDCAT that is working properly.
If the problem persists, REDCAT is the most
likely cause of the problem; instruct customer
to return that REDCAT and power supply.
Check
that the batteries being
used in the microphones are
charged and are the proper
type.
the original microphone with
another REDCAT that is working properly.
Install Lightspeed NiMH batteries that are
fully charged.
Check
that a known good microphone works with the REDCAT being tested.
Turn off all infrared microphones and disconnect all other inputs from REDCAT; check
green LED for activity.
Check
that the sensors are not in
direct sunlight, or near any
other source of possible IR
interference.
If problem persists, REDCAT is the most likely
cause of the problem, instruct customer to
return that REDCAT and power supply.
Check
that the equalizer is free of
dust.
Exercise the equalizer sliders from top to bottom 4 or 5 times to remove any dust.
Test
If static is heard with the known good system, the microphone is the likely cause of the
problem.

away from possible sources of
IR interferrence.

Resolution
The indicator should be no higher than the 9
oclock postion.
The microphone should be worn at the level
of the collarbone.
All bands should be at 50%.
If the feedback stops, the original microphone is the most likely cause of the problem.
If the feedback continues, the problem is
most likely caused by the REDCAT.
The indicator should be between the 7-9
oclock postion.
The microphone should be worn at the level
of the collarbone.
all bands should be at 50%.
If the volume level remains low, the problem
is most likely caused by the REDCAT.
Change one microphone to the opposite
channel.
The microphone may have become blocked
by clothing or turned to face the user.
Sunlight and uncovered windows can adversely affect performance.
if the intermittent operation stops, the original microphone is the likely cause of the problem. If the problem continues, the REDCAT is
the most likely cause.
