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
• Conrm batteries are charged
each night.
• Conrm 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 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.
Hearing Static
• Ensure that no other REDMIKE/LT71/
HM70 is operating on the same channel.
Low Volume or Feedback
• Ensure the pendant style 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 705iR on. Conrm that the
POWER light ashes RED one time
when turned on.
• Conrm signal is being received at the
705iR. The IR signal light will be GREEN
indicating a signal is being received
from the microphone.
• Conrm that REDMIKE is turned on.
There will be a BLUE LED on
the microphone to indicate it is
powered on.
