Tektronix 2445a Questions

Hi,

I just purchased a Tek 2445A o'scope
for home hobby use and have two questions.

1) How do I activate the diagnostics? I'm use to
modern digital scopes at work where everything
is menu driven and pretty obvious.

2) When operating any of the controls, all of the
front panel LEDs flicker in unison. Is this
common or indicative of a serious problem?
Could it be dried out power supply caps?
Other than being an annoyance, does it affect
scope operation in a any way?

I'm in the process of ordering operating and
service manuals.

Any info would be appreciated.

Thanks much,
Joe
