TDS3034C does it have a clock/ram battery?

Recently got a used TDS3034C that was in unknown working condition.  Seems to work so far.  Does it have a clock/ram battery that should be changed out as preventative maintenance?  I have read the earlier versions have one of those Dallas clock chips in them.  Well aware of those from old PC's...

Ok, answered my question.

This does have a Dallas DS1742W-150 in it.

I actually acquired 2 of these.  One seemed to work fine.  One had obvious damage, the BNC and ground stud on the back were bent sideways and things rattled a little.  Drop damage likely.  I powered it up and got a white screen.  Elected to take that one apart to investigate.

The sheet metal was bent up inside around those 2 protruding items.  Easy enough to straighten.  The rattling was some broken off plastic bits.  Also noticed the shield over the inputs was dislodged a little and had to be snapped back in place.  But, the root cause of the white screen seems to have been a ribbon cable between the power supply board and main board was popped off.  On reassembly, made sure everything was in place.  It now boots up and seems to be working.
