[TenTec] Paragon 2 Memory Battery Back-up

[sbjohnston at aol.com]

Interesting... my Paragon 585  has a 9-volt battery clip for either 
alkaline or nicad battery backup of the clock and memories when the rig 
is unplugged from 13.8 vdc power.  The operating software is 
non-volatile.

Subject: [TenTec] Paragon 2 Memory Battery Back-up


I have been having a lot of fun with my newly acquired Corsair 2.  
Consequently,
I have decided to look for a nice clean Paragon 2.  I downloaded the 
manual for
them on the internet and it says the microprocessor has a power cell in 
it to
maintain memory for 10 years.  Well those radios are now well over 10 
years old.
The power cells must have died years ago.

How in the world do you maintain memory in a Paragon once the power 
cell in the
microprocessor has worn out?  There is no external battery!  Do you 
replace the
microprocessor and is it available and what do they cost?  (Seems to me 
to be a
problematic design).  Is it possible to hang an outboard power source 
onto the
microprocessor once it's internal power source fails?  If so, how is 
this done?
(Just to be safe, I checked the schematic around the microprocessor and 
as
suspected, I find no external battery on the diagram).

I sure would like to hear from those more knowledgeable then me on this 
topic.
This has me concerned and I have not, to date, found a Paragon 2 to 
purchase.  I
would suspect there is some easy remedy for this problem, or at least,  
it is my
hope there is a simple solution available.

Thanks for reading this.

Lee, w0vt
