Subject: [Standard] 5608 Turn Off Problem
Message-ID: <6.2.1.2.0.20050823151547.2ad6b608@mail.comcast.net>

I have a 5608 that recently received water damage.  It was submerged for an hour or two while connected to 12VDC.  After removing it from the vehicle and allowing it to dry out, it didn't turn on or do anything.  I let it sit for a few more days.  While probing around near the from panel, I apparently hit something that caused it to turn on (and a master reset).  It appears to have some functionality now, it receives on VHF, receives with some sort of distortion on UHF, etc. but it won't turn off.  Neither the remote turn off on the microphone nor the front panel switch will turn it off.  Disconnecting power will obviously turn it off.  Reapplying 12V will momentarily turn it on and then off.  Using either the remote switch or front panel switch, I can then turn it on, but not off.  Anyone have any clues or suggestions?  I am thinking maybe I should do an intentional reset, but I have forgotten how to.

I would suspect that there has been electrical damage to the processor. 
However, I would remove the boards from the case, wash them in distilled 
water to remove anything that might have formed a short. This could be the 
flux used when the radio was first made. I would use a brush that will 
remove any residue without scratching the board.

I would then bake the boards in an oven at no more than 150 degrees. The 
oven light will build up enough heat to remove the moisture. I would leave 
the oven in the bake for a day or so to ensure that all the moisture is 
driven off.

After this I would apply power and see how the radio responds. If you 
cannot control the radio, it is time to send it to the radio doctor.
