E4402B Battery/License Codes

I Have a used Agilent E4402B - S# MY41440947 - Firmware A.14.06 

I haven't used it in about 6 months. I turned it on the other day and it said I need to run full alignment.

Also the time/date are wrong so I assume the battery is dead in it. Looking thru the options I see I also have none. 

1D5, 1DR, 1DS, AYX are on the back panel but only B72 & 290 show up on screen. The AYX  card is missing  too so unfortunately  someone has been inside it before. The only history I have is that it originally came from Boston Scientific.


1 - What is the part number for a new battery?

2 - Is there any way to recover license codes?



Thanks , Jeff - KD0ORH
