NOTE! Most problems are directly related to low
battery power. Please run through the “Battery
Check” items rst. For remaining troubleshoot-
ing, use known good, fully-charged batteries.
Battery Check
•Conrm batteries are charged
each night.
•Conrm proper batteries are
used. The REDMIKE requires the
Lightspeed BA-NH2A27 sensing
battery for proper charging.
•Make sure the REDMIKE is turned off
while charging so that it will attain
a full charge. Full charge will last
seven hours.
•Inspect the battery contacts. Clean
and adjust if necessary.
Hearing Static
•Ensure sensor is in optimum
location (refer to sensor placement
in manual). A single sensor will
cover a 1600 sq. ft. enclosed
classroom.
•Ensure that no other REDMIKE/
LT71/HM70 is operating on the same
channel.
•If an external microphone is in
use, try another REDMIKE that is
known to be working (if available) to
isolate the problem. If static persists
with “known good” microphone,
the REDMIKE input jack will need
service.
Low Volume or Feedback
• Ensure microphone is positioned
appropriately, just below the
collar bone.
•Check volume level on the amplier.
If the volume is too high, feedback
will occur. Adjust accordingly.
No Sound From Speaker
•Turn the 820iR on. Conrm that the
POWER light located on the power
switch is on.
•Conrm signal is being received at
the 820iR. The IR signal light will be
lit (RED) indicating a signal is being
received.
•Conrm that REDMIKE is turned on.
There will be a BLUE LED on
the microphone to indicate it is
powered on.
TROUBLESHOOTING GUIDE
1
TIPS ON CLASSROOM AUDIO
Avoid wearing jewelry that may rub or bump against
the microphone.
Turn the REDMIKE off during private conversations with a student,
parent, or other classroom visitor. You can also cover the LED
lens on top of the REDMIKE to block the signal.
Recharge batteries each night. When recharged nightly, operating
time (actual usage) for the transmitters will last through a typical
school day.

adequate amplication (approximately 5 – 10 dB) above
ambient room noises.
