Hearing from Motorola H700

Good morning!! ive been thru this before, try tapping your phone volume while your talking to your party, it shold be seen on your phone screen as earpiece volume than turn it up and when you have the volume where you want it dont forget to tap the set on your phone, another prob i had was some times there is a small protective plastic film on the ear holes on the tooth and one on the mike sometimes, i could hear my party but they couldnt hear me until i discovered that lil peice of plastic. remember your key codes are either 0000 or 1234. good luck m.m.
