Hi Jeff,

looks like the UPS battery and the 5061B draws too much current....together.... just charge-up the UPS and when it is OK plug the other unit in....

This is my first guess.

Rgds Ernie..

Hi.

e lost power for several days after the hurricane last weekend.  As a 
recaution I pulled the AC plug for my 5061B from the UPS it's attached to since 
 was pretty sure that we would be without power for a while and didn't want to 
ave the unit plugged in when the power came back in case there was a surge.

ower was restored on Tuesday but I only got around to powering up the system  
his morning.

hen  I plugged it in, it immediately started making a buzzing sound - alomost 
ike an alarm.  The system appears to be working normally otherwise - alarm LED 
n, clock advancing, etc.

've never heard this buzzing  before during power up.

ot knowing what the issue was, I powered the system down.

nyone have any clue before I start tearing it down?

TW - I don't see any mention of this in the manual.

hanks in advance.
