Begin by located a small light next to the channel/power button on the headphones (this tiny light will either be blue or green when the headphones are powered on).

A blue status light indicates that the headphone is in scan mode (click the channel/power button once o scan for the next active channel). 

A green status light indicates that the headphone is in manual mode (click the channel/power button multiple times to step through the channels one by one. The headphones will light up all BLUE when they are on channel #1, RED for channel #2, GREEN for channel #3, Cyan for channel #4, Champagne for channel #5, and so on). 

To switch between the two modes, turn the headphone off and then press and hold down the power button until you see the little status light change from green too blue or vise versa.

(Pressing the volume button in puts the headphones in dark mode which will turn the main LED features off).
