The other day my JVC DR-M10 recorder suddenly "locked out" all attempts to turn the timer on or change channels. From the remote, I have pressed the timer button countless times and also the channel up/down and the direct channel numbers - but nothing will turn the timer on or change the channel. I can add and change timer settings but I can't cancel any. All other functions on the recorder seem to work as normal. Can still record without the timer but now it's "locked" on channel 2. Anyone have any idea what would "lock up" only the timer and channel changing, yet leave all the other functions working normally? I have changed the batteries on the remote, so it isn't that. I now have resorted to unplugging the machine and I'm hoping everything corrects itself. Now I have to figure out how long the machine needs to be unplugged for all the settings to be erased from memory. I know 24 hours is not enough.
