HAC4 stops recording

Hi all,

today I was using an HAC4 I got not much time ago.
I started the recording pressing the two left buttons. The "mountains"
started blinking, everything ok.

After about one hour of riding, I heard a short beep. I didn't pay much
attention as I thought it was some "1 hour" signal.
I'm pretty sure I had not pressed any button.

When I got home, I pressed the two left buttons to stop recording, but
to my surprise the unit *started* recording, i.e. it was already stopped.
So I downloaded the data on the pc and I noticed that the record
actually stopped after about one hour, probably when I heard the
aforementioned beep.

Now why did this happen? Do someone with more experience with the HAC4
knows the answer?

(Very annoying as I lost even the basic details (distance, time, average))

Thanks,

Francesco

Check the memory. It sounds like you failed (or forgot) to delete
previous files.

On the HAC-4, it does a "rolling" deletion of older files. It will always
keep only the last 64 hours of ride info; there's no way to force it to not
drop off the older ones (in other words, no way to keep something in the
unit; you have to download it to your computer if you want to have access to
the info down the road).

Huh, interesting. Thanks Mike.

This happened to me once in a little over one year. I also
remember hearing the beep. Interestingly, it was on the first
ride after I changed all four batteries. It hadn't happened
before, and hasn't happened since.
