Philip, No I haven't had a chance to contact Tascam (this unit hasn't
seen more than 20 hours of usage). I will remove the batteries and
see what happens. When it rains, it pours...two weeks ago I was going
a mobile recording and my back-up recorder (I wire in a Sony PCM-R300
DAT) didn't want to track at the event). Luckily, I didn't need to
turn to my second unit, but it still makes the night a little more
spooky. Then I turn around and last week had the field recorder start
doing this stuff.
I probably should complain too much, as I've not gotten burned outside
the studio. Anyway, you gave me a starting point. So I shall......
Thanks,
Blas

The unit should pick whatever power source is the strongest, and
switch invisibly.

It sounds like your external source is not providing enough power and
it is reverting to exhauseted AA internal batts.
There is an indicator on the lower left of the display that tells you
if it is powering through internal batts, or it is accepting 12Vs of
power externally (the little edison plug icon). That's your first
troubleshooting clue.

hello,

I had the same problem with internal rechargeable batteries in the HD-P2. i
was wondering, since i am also using external Tekkeon battery, fully
charged, why my unit was shutting down once i restart it! to my surprise, I
had to fully charge my internal batteries so that they have enough voltage.
this IS strange to me, and i think it shouldn't be this way, but for now as
long my internal batteries are fully charged, I can use external battery
power with no problem.

what if you remove the internals?

in the menus of HD-P2 it is possible to see how much voltage each power
source gives at any moment. of course, i have checked that, and HD-P2 is
running off my external Tekkeon battery, but ONLY if internal batteries have
sufficient voltage as well. and this is what i find strange.

it indeed shows it is accepting power from external battery. but no matter
that, it will also shutdown if the internal battery's power is lower than 9V
or something.

I did remove the internals and YES it stays powered up. Tascam needs
to address that issue. I would think, if you have the AC source
plugged in, the batteries should be able to be dead and still have the
unit operate. Poor design item there! I hope someone can get Tascam
to look at this issue and make a software fix.
Again, thank you all for jumping in and giving me a direction to start
in.

Mine will power properly from the AC supply w/ no or deadish batteries
in it. You might want to check your PSU voltage against spec and call
Tascam support and talk to them about this.

It should by spec- it will pick the highest voltage and power from
that.

You probably need to have your recorder checked by a repair tech.

but i have the same problem as Blas. at least, two people on this group
experience the same issue.

is there anyone else with HD-P2 and shutdown problems with external power
when internal batteries have insufficient voltage?

Gentlemen, I finally got a chance to get a call into Tascam support
(long,long wait time) anyway, they said it SHOULDN'T be doing that and
I need to get it to a Tascam dealer/repair shop. Luckily there is a
shop here in St. Louis, sadly it's not one of the friendliest places.
But beggars can't be...never mind.
