Greetings:

You may want to check your power supply -- wall wart.  Is almost looks
like a low voltage or limited current issue.

Get another 12v DC power supply with at least 700ma of current.

The battery is a non issue for now.  It only holds the presets in 
memory and has nothing to do with booting up.  Any 3.2v Lithium coin 
cell will actually work.
