[TenTec] Any experts on the MFJ 259B Antenna Analyzer out there?

[Stuart Rohre]

Misplaced the 259B manual.  I know we will find it after asking this
question.

The 259B has a time out function, to save the batteries.   Is there a way to
defeat that automatic shutdown?  Like if you are running on the wall wart,
and do not have to worry about power?

I am sure it must be a control pin of the control microcomputer, and I may
have to find that and figure out a way to defeat the time out myself, but
figured there might be a multibutton push way to do so from the front panel.

I think my 269 which is not with me at the moment, does not time out as fast
as the 259B I was just using.

Any suggestions, directions, or experiences welcomed!
Thanks and 73,
