[time-nuts] Buzzing 5061B

Hi.
 
We lost power for several days after the hurricane last weekend.  As a precaution I pulled the AC plug for my 5061B from the UPS it's attached to since I was pretty sure that we would be without power for a while and didn't want to have the unit plugged in when the power came back in case there was a surge.
 
Power was restored on Tuesday but I only got around to powering up the system  this morning.
 
When  I plugged it in, it immediately started making a buzzing sound - alomost like an alarm.  The system appears to be working normally otherwise - alarm LED on, clock advancing, etc.
 
I've never heard this buzzing  before during power up.
 
Not knowing what the issue was, I powered the system down.
 
Anyone have any clue before I start tearing it down?
 
BTW - I don't see any mention of this in the manual.
 
Thanks in advance.
 
Jeff
