REDCAT (RC2)
No sound from
speaker
Check that blue power LED on front of
RC2 is lit.
If not, verify all connections are snug from the AC
connection to the power supply, and from the
power supply to the RC2. If all connections are
secure, determine if the outlet is working or test
with a known working power supply.
Check that the red LED above the corre-
sponding channel volume control
illuminates when speaking into
the microphone.
Verify that the frequency of the microphone
matches the frequency group of the RC2.
G1=microphone marked with“G1”
G2=microphone marked with “G2”
Verify that the RC2 channel A & B
volume controls are set to just
below mid-range.
Adjust volume level to achieve desired loudness. If
still no sound, try connecting another audio device
to one of the inputs.
Verify that sound from the “Audio In”
source can be heard.
If the audio from a source can be heard, the micro-
phone is the most likely cause of the problem.
Test the original microphone with a
known good system.
If the problem persists, the microphone is likely
the cause of the problem.
Static is heard
from speaker
Check that the battery(ies) being used
in the microphone is charged
and is the proper type.
Install the proper NiMH battery(ies) that is fully
charged.
Test the original microphone with
another system that is working
properly.
If static is heard with the known good system, the
microphone is likely the cause of the problem.
Test whether a known good micro-
phone works with the RC2 being
tested.
If the problem persists, the RC2 is likely the cause
of the problem.
Check if two microphones are being
used that they are on different
channels.
If needed, change one microphone to the oppo-
site channel.
Check RC2 placement in the room. Evaluate the RC2 location in the room and adjust
as needed. It should be located near the center of
the room along a long wall. Avoid placing it near
obstructions.
Check that the RC2 is located away from
possible sources of IR interfer-
ence.
Direct sunlight and Plasma monitors can adversely
affect performance.

Feedback Check that the volume on the RC2 is not
set too high.
Reduce volume as needed until feedback issue is
resolved. Remember the teacher should barely be
able to hear his/her own voice at optimum volume
levels.
Check that the microphone is being
worn properly.
The top of the microphone should be worn at the
level of the collarbone. Adjust lanyard accordingly.
Check that the tone is set to the mid-
point.
Set the tone indicator to the 9 o’clock position
and then adjust as needed to eliminate feedback.
Test the original microphone with
another system that is working
properly.
If the problem persists with the other system, the
microphone is likely the cause of the problem.
Low volume Check that the volume level on the RC2
is not set too low.
Position the volume indicator at the 12 o’clock
position and then adjust as needed for normal
operation.
Check that the microphone is being
worn properly.
The top of the microphone should be worn at the
level of the collarbone.
Check a known good microphone on
the same channel with the RC2.
If the volume level remains the same as the
original microphone, the most likely cause of the
problem is the RC2.
Drop-out /
intermittent
operation
Check if two microphones are being
used that they are on different
channels.
If needed, change one microphone to the oppo-
site channel.
Check that there is no obstruction be-
tween the RC2 and the micro-
phone.
Make sure the microphone is not blocked by
clothing or turned to face the user.
Check RC2 placement in the room. Evaluate the RC2 location in the room and adjust
as needed. It should be located near the center of
the room along a long wall. Avoid placing it near
obstructions.
Check that the RC2 is located away from
possible sources of IR interfer-
ence.
Direct sunlight and Plasma monitors can adversely
affect performance.
Check that a known good microphone
works with the system being
tested.
If the intermittent operation stops, the original
microphone is likely the cause of the problem. If
the problem continues, the RC2 is the most likely
cause.
REDMIKE2
(RMT2) will not
power on
Check that the correct battery is being
used.
Use the Lightspeed NH2A27 NiMH rechargeable
sensing battery as it is the only kind of battery that
will properly charge with the RMT2.
Check that the battery is installed prop-
erly.
Ensure that the polarity is observed.

Check that the battery is charged. Substitute a known good battery and see if it
charges in the microphone. If it does charge,
replace worn or defective battery. Typical battery
life is 1-2 years.
Check that battery contacts are not
obstructed.
Ensure that there is no object preventing good
contact between the battery and contacts.
RMT2 won’t
charge
Verify that the correct battery is being
used.
Use the Lightspeed NH2A27 NiMH rechargeable
sensing battery as it is the only kind of battery that
will properly charge with the RMT2.
Verify that the RMT2 charging circuitry
is working properly.
Substitute a known good battery and see if it
charges in the microphone. If it does charge,
replace worn or defective battery. Typical battery
life is 1-2 years.
Verify that the RMT2 is being seated
properly in the cradle charger.
When the RMT2 is properly inserted in the cradle,
the LED on the charger should turn solid red.
Verify that the cradle charger is working
properly.
The LED on the cradle charger should turn solid
red when the microphone is inserted. If no LED’s
light, try using a known good cradle charger. (If
there is a blinking red LED, that indicates no bat-
tery is sensed. A green blinking LED indicates a
non-Lightspeed battery has been installed (pos-
sibly an alkaline battery).
Verify that the cradle charger power
supply is not damaged or defec-
tive.
Try known good charger power supply.
REDMIKE
Share2 (RMS2)
will not power
on
Check that the correct battery pack is
being used.
Use the Lightspeed NH2APK NiMH rechargeable
battery pack as it is the only kind of battery pack
that will properly charge with the RMS2.
Check that the battery pack is installed
properly.
Make sure that the polarity is observed.
Check that the battery pack is charged. Substitute a known good battery pack and see
if it charges in the microphone. If it does charge,
replace worn or defective battery pack. Typical
battery life is 1-2 years.
