Disklavier

Hi,
I have had my DC2A for a week now, and have had the thermostat 
indicator turn off the piano quite a few times.  It's going to be a 
while before the dealer can get a tech out to my house (my bad 
schedule, not theirs) and wondered if anyone had any tips in the 
meantime.  I assume this is a safety mechanism, and that it is 
supposed to shut down to prevent heat damage, but I wonder if it's 
regulatable or has more to do with ambient temperature, etc.  Also, 
will it reset itself and return the piano to play if I leave it 
alone?  I've been a big chicken and have been turning the entire unit 
off when the message comes up.
Other than that, I love it, despite its price tag :)
Thanks
Amanda
