I've just recently replaced my 8830's scratched housing....in doing so, I seem to have broken off the UP VOLUME button inside the unit. I'm fine making calls as they default is LOUD, however when I activate the speakerphone of course it's now down to the bottom and I can't seem to adjust.
Question...."is there a manual adjustment on the 8830 that can raise the speakerphone volume without using the buttons on the side ?"
