TROUBLESHOOTING GUIDE
If you review these instructions and still have questions, write down the serial
number and model number of your system and call Lightspeed Technical Services at
800.732.8999, 5 a.m. – 5 p.m. PST.
NOTE: Most problems are directly related to low battery power. Please run through the
“Battery Check” items rst. For remaining troubleshooting, use known good, fully-charged
batteries.
Battery Check
• Conrm batteries are charged
each night.
• Conrm proper batteries are used.
The REDMIKE requires the Lightspeed
BA-NH2A27 rechargeable sensing
battery for proper charging. The LT-71
& HM-70 require NiMH AA rechargeable
batteries.
• Make sure the REDMIKE is turned off
while charging so that it will attain a full
charge. Full charge will last eight 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 amplier. If
the volume is too high, feedback WILL
occur. Adjust accordingly.
No Sound From Speaker
• Turn the REDCAT on. Conrm that the
POWER light located on the front panel
switch is on.
• Conrm signal is being received at
the REDCAT. The IR signal light will
be GREEN indicating a signal is being
received.
• Conrm that REDMIKE is turned on.
There will be a BLUE LED on
the microphone to indicate it is
powered on.
