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 NH2A27 rechargeable 
sensing battery for proper 
charging. The REDMIK Share uses 
the NH2APK rechargeable battery 
pack. The LT71 requires two NH1 
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).

•  Ensure that no other REDMIKE/

LT71/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 705iR on. 

Confirm that the 

POWER light flashes red one time 
when turned on.

•  Confirm signal is being received 

at the 705iR. 

The IR signal light will 

be green indicating a signal is being 
received from the microphone.

•   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.

If you review these instructions and still have questions, write down the 

serial number and model number of your system and call Lightspeed
