We bought these radios a couple of years ago and they worked. I removed the batteries and stored them in the dresser for a couple of years and now I wanted to use them and can't seem to get them to work? All buttons and features seem to work except the only time I get any static is when I hold down the M buton? They both act liked they're squelched? I can't find the manual either! Xact doesn't respond to emails. Any Ideas or suggestions? Thanks, Joe
