The +W- setting On the Baofeng 1701 DMR radio is the highest transmit power setting available, and its only meant to be used in an emergency as I think it can damage the radio if used too much. Problem is, if messing around with the radio it's quite easy to accidently press the right [or wrong] buttons to enable this setting. I've done it several times now. The second problem is how hard it is to reverse the +W- setting back to a normal 1 Watt, 5 Watt or whatever you want to use. Or at least it seems really hard when you don't know what to press.
I was there pressing every button combination under the sun and still couldn't figure out how to lower the power. It's actually really easy when figured out. Please note: this is for radios that have OpenGD77 installed. The process will probably be a little different with the stock software.
How to reverse the +W- power setting On The Baofeng 1701 [with OpenGD77]
Press and hold down the lowest button on the side of the radio. While holding the button down press the P1 button on the keypad to lower the transmit power. I don't transmit on my radio so I have it on the lowest setting, which is 50mW. If you want to higher the power you can either press and hold down the P2 button and it will go up in increments on at a time, or you can press and hold down the lowest side button while pressing the P2 button.
Do note: the only way to reach the +W- setting is through pressing and holding the P2 button alone. Holding down the side button while pressing the P2 button to increase the transmit power will go up to the regular highest power setting, which is 5 Watts.
