TROUBLESHOOTING GUIDE

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.

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 & 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 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.

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.

No Sound From Speaker

Turn the 850iR on. Confirm that the

POWER light located on the front panel switch is on.

Confirm signal is being received at the 850iR. 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.

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.
