PEAK light stops lighting. 

6.  IR Lens -

 This window is used to capture the infrared signal sent from the AR299m 

receiver during the IR SET to channelize the transmitter. The battery cover must be 
open and the IR Lens facing towards the receiver to load the selected channel.

Designed for use in adjusting the CH88 input GAIN control (See #5
