ALL PROBLEMS: Most Problems are
related to low battery power.
SOLUTION: Battery Check
• Confirm batteries are charged
each night.
• Confirm proper batteries are
used. The REDMIKE requires
the Lightspeed BA-NH2A27
rechargeable sensing battery
for proper charging. The LT-71 &
REDMIKE Share require NiMH AA
rechargeable batteries.
• Make sure the microphones are
turned off while charging so a full
charge is attained. Full charge will
last eight hours.
• Inspect the battery contacts. Clean
and adjust if necessary.
PROBLEM: Hearing Static
SOLUTION: Follow these steps to
eliminate 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/LT-
71/REDMIKE Share is operating on
the same channel.
• If the optional iR media connection
is in use, set the microphone to
Channel A.
PROBLEM: Low Volume or Feedback
SOLUTION: Follow these steps to
eliminate low volume or feedback.
• Ensure microphone is positioned
appropriately, just below the collar
bone.
• Check volume level on the
amplifier. If the volume is too
high, feedback will occur. Adjust
accordingly.
• Adjust the volume level on the
back of the optional REDMIKE VC.
PROBLEM: No Sound From Speaker
SOLUTION: Follow these steps to
produce sound from speakers.
• Turn the REDCAT on. Confirm that
the POWER light located on the
front panel switch is on.
• Confirm signal is being received at
the REDCAT. The IR signal light will
be RED indicating a signal is being
received.
• Confirm that REDMIKE is turned
on. There will be a BLUE LED on
the microphone to indicate it is
powered on.
Note: Most problems are directly related to low battery power. Please run
through the “Battery Check” items first. For remaining troubleshooting, use
known good, fully-charged batteries.
