Programming Respironics BiPAPPLUS M Series

On my previous Respironics model I was able to have the control button lights turn off when the unit started to operate. Now I have a the BiPAPPlus M Series and cannot find how to program this feature so the lights go off. It is very annoying because the lights are bright in a dark room at night and I have to place a garment over the unit to block out the lights. Any help will be well appreciated!

There's a simple solution.
A _very small_ piece of tape on top of the light.
e.g., duct tape, or anything thick and dark.

There is no way to turn off the blue light in the machine itself. It is simply always on. Only thing you can do is cover it either permanently with tape or throw something over it to block the light.
