[TenTec] Paragon brains gone

[Chas Nagel]

When I purchased my Paragon about 5 months ago it came with a warning label inside near the battery holder regarding use of alkaline batteries. Use only rechargeable battery and the procedure stated below by Mark.

  Ken,

This happened to me once. Did everything you described. Replaced rechargable battery, still no joy. Then tried powering up with out battery connected - worked fine. Connected new battery (while still powered up) and haven't had a problem since: even when I turn off power supply a week or two it is OK. I would try a new battery. I plan on replacing mine again soon (it is about 2 1/2 years old.)

Incidentally, I put my battery in a small zip-lock bag (made for small parts) and brought the wires out towards the top of the rig. Hopefully if the battery ever decides to leak or something bad happen the bag will catch the chemicals and not drip down on the interior (boards).

Incidentally, the manual I received from Ten Tec, when I purchased my Paragon in 2000, says you can use an alkaline or ni-cad. THIS IS WRONG! I almost had a disaster. Luckily I noticed the battery (alkaline) getting warm before I put the covers back on and removed it. DO NOT use an alkaline in a Paragon unless you have disabled or know the charging circuit is not connected. Otherwise - Use ONLY a rechargable. I called Ten Tec on it - don't know if they ever changed their manual. I know this has been mentioned on the list before, but figure it won't hurt to bring it up again.

I was cleaning around the shack and had the 12 VDC power removed from my 
Paragon 585 (not a Paragon II) for an hour or so. When I hooked it back 
up and turned on the 585, the controls are not working and the display 
is not there. I have tried the RESET button on the right hand side of 
the rig, and this does not fix it. I have not yet opened it up and 
checked the voltage of the 9V NiCad memory battery. It has been 
connected to 12 VDC power for a day now, and I would expect that battery 
to have recharged by now. If that battery is dead will the radio not 
work, or will there just be no memory when the radio is powered off? Are 
there any other reset methods I need to try? Hold a certain button while 
powering up?

Thanks DE N6KB
