Disklavier

As a computer geek, I have had UPS systems on my computers for years. 
The Disklavier controller and mechanism is just like a computer and 
deserves the same protection. APC makes a UPS that is adequate for a 
Disklavier that one can buy for about $40.00 at CompUSA or Office Depot. 
A size of 350va or greater should do fine. I plugged my Disklavier into 
a UPS the day I got it. In big cities, a bigger issue is brown-outs, 
especially during a hot summer or while an Air Conditioner is turning 
on. A UPS will take care of all these power problems. A premium grade 
UPS also "conditions" or "cleans up" the electric supply. Some of you 
may want to ask the CompUSA tech about the different features a UPS may 
have.
