[Yaesu] FT 726 R

[VA3DG]

Hi Mike....

As a result of  a Google search, I found the following article from QRZ 
Forums. I think you'll find the battery info you need in the 2nd paragraph. 
I hope this is the battery info you need.

Cheers....

A few months back I bought an FT-726R. I had fun with it for a while (this 
was back during the VHF/UHF contest); it was working perfectly except the 
lamp bulb for the meters was out, the memory backup battery was dead, and 
some of the pots were scratchy.

Well, in the last couple months I've been working on it. It was equipped 
with the 2M, 430, and "HF" modules. I had no need for the HF module so I 
sold it, and used the money to buy the Piexx digital retrofit tone board for 
it. I desoldered and replaced the CR-2025 backup battery; and replaced the 
bulb for the meters. I also removed all the knobs and cleaned them, and 
cleaned the pots with some contact cleaner (did not remove them to do that). 
I tested the bulb, working fine, and the battery connections are good.

Put it all back together and turned it on. The display reads 0.000.00, and 
it will only tune up to 9.000.0. Trying to TX, the display reads "E A", and 
none of the mode buttons work. It is stuck on LSB. I can hear static through 
the speaker, but tuning between 0 and 9 doesn't seem to change the static at 
all. Pressing any of the other buttons or turning knobs does nothing.

I did some searching on the net and see that the modules need to be 
connected using the bottom connections first (default module), then the 
middle, then the top. Well, the 2M module is plugged into the default, then 
the 430 is in the middle, so that's OK. I also saw that when changing the 
modules you need to cycle the memory backup switch to do a reset. Tried that 
with no luck. I even tried removing the Piexx board and plugging the 
original back in, no change.
