Hi Guys, I have a Symbol MC 50 PDA (http://www.posmicro.com/symbol/mc50.htm) to which I want to connect a headset. Now it's a stereo 2,5mm jack (Tip, Ring, Sleeve), but I do not know the connections and technical specifications. I'm not sure if this is the right forum for that, but I couldn't really find a other "proper" Forum as sofiticated as MSFN. I need to know especially how the microphone should be connected and how much "power" (how many volts) the PDA can give for the microphone??? Anybody know? Thanks in advance!!!
