[Kenwood] TR9130

[nittner@comcast.net]

I picked up a used TR9130 2 M all mode rig. There is no book with it to look for information so I hope that someone on the list can give me an idea of any possible problem.
When I powered it up the display was flashing 6.000 pushing the PTT gives a solid 6.00 reading and about a 6 on the meter into a dummy load.
The rig was not used for a long time and I thought that the 9volt NiCad needs charging but after having it on over night it is still the same.

Everything else seems to be operational(squelch, rf gain etc)well not everything because it's not working and turning the dial will not change the display. Is there an other hidden Li battery?
    Any help will be much appreciated. 
                          TIA Jurgen N9RD/4
