[Repair] Fix Forest Helmet Intercom Not Turning Off

This video shows how to fix the Forest helmet intercom when you can't turn it off by pressing and holding the power button for a couple of seconds. This is a known issue of the intercom and one of the ways to turn it off is to literally remove the battery connector inside by tearing the intercom down to shut it off.
Another way I discovered along the way on my Forest intercom is you can long press the "M" button beside the power button for a couple of seconds and it will force it to turn off.
