Rapid Beeping on 6400

Last night my 6400 started sporadically beeping rapidly, seemingly from a PC speaker inside the 6400 box. The beeping lasts about a minute and then stops. This has happened 3 times so far, 2 last night with SmartSDR shut down and just now with SmartSDR connected and listening to a 40m net. The beeping lasts about 60 seconds and then stops. This does not seem to affect operation, as I can receive as noted above, and checked into a MARS net earlier this morning and was able to copy the digital messages as well. I cannot find any reference to beeping by the 6400 itself, either on the FlexRadio forums or from a general web search. My questions are: 1) what is causing the beeping, and 2) can (should) I do anything about this?

Thanks, Mark, AC3EW

    Mark, is it sending morse code? If so, let us know what your radio is trying to tell the world (big smile).

    @W7NGA After some in-house jokes about alien messages, if the beeping is Morse Code, it's a series of dits like when someone makes a CW typo (a looooonnnng series of dits).

    Please disregard. The beeping is from my UPS unit telling me I need to replace its battery, which I am attending to. The behavior is exactly as described on the APC website. My hearing isn't the best (which my Flex radio has helped with greatly in receiving signals) and it sounded like the beeping was coming from the 6400. Thanks everyone for entertaining my befuddled analysis of symptoms.

    Glad you got it figured out.

    I was trying to figure out when we installed a speaker/beeper in the radio (as there is no way for the radio to actually beep).

    I want to commend Mark on the process he followed with this issue. Mark posted here and asked if any other customer had seen this issue. He then submitted a Helpdesk request and followed up by attaching a sound recording. Then, when he found the cause, he sent a note to disregard the issue to the community and the Helpdesk request.

    Frankly, we couldn't ask more from our community and Mark as a customer.
