Agilent E4402B Spectrum Analyzer repair Align Now All Required

[startronic]

Hello Guys,...

I have an Agilent E4402b, with the display message Align now All required, even after doing the procedure Align Now, after restarting the E4402 back with the same problem, in the system menu in Shows errors appears the error code - 222,

I reshoot Aling Now again, and now you get the message DATA OUT OF RANGE on the display.

Here in Brazil Agilent (Keysight), not of due support, say that it is already obsolete.
So I'll have to fix it myself,
I would like to request judo from the forum forum, if any have the service manual for this model I am very grateful.

Thank you
