Excerpted from "Monitoring Times", Vol. 4, No. 12, Dec., 1985
"Recently, ICOM has endured substantial criticism in the hobby
press regarding the consequences of a failed lithium backup
battery for the RAM (random access memory) microprocessor circuitry.
It is true that if the battery fails (they normally last at
least five to seven years), the receiver will have to be sent
back to ICOM for reprogramming. The entire cost to the customer
is $25 including battery replacement, reprogramming, full check out,
and return postage. But some preventitive maintenance can avoid
the consequence entirely. . . ."
(The article then proceeds to tell how to use a 5 volt supply to
retain the contents of memory while replacing the battery)
