Hi All,

My TH-78A has decided it requires a new back-up battery. At this stage I
have not opened the radio to see what is required, but if anyone has any
information, advise on the task before I start on it, this would be of great
help.

Thanks for the info, looked at every download, and could not see the info on
how to do the back-up bat change.
Must be looking in the wrong place. Sorry

Regards

Kev.

hi,

Just follow the instructions for me-1 installation, you open up the case
the same way to replace the lithium battery.
It is soldered in place so try to get one with tabs on it,
avoid soldering to the battery directly.

Please use a static wrist strap and static workstation pad
when you are working on this radio, the cmos circuits can
get damaged from static.

One thing to watch out for is the small chip resistors on
the top encoder board, they can break off if you are not
careful.
