Re: Fitting TS with Printer, electrical issues

Hello Alan and all:

The standing instructions in San Diego County for the
TSx, polling place and power failures are that we are
to immediately contact the ROV so they can bring us
out a generator. Many polling places need electric
lighting just to be able to read the Roster of Voters
and the paper ballots.

Yes, the TSx as well as the Acuscan can theoretically
run for a couple of hours on batteries but as the
equipment sits around your house (or even in the back
of your car) for a week or more, I'm always concerned
about the level of charge in the back up batteries.
If we set up in a polling place and the power failed
immediately due to overloads (the most likely scenario
IMHO) we might not be able to open. I've plugged the
equipment in and saw that they there was only about
50-60% charge on one of of them. However, after an
hour or 2 on line current, they are usually fully
charged.

Thanks, Ed Kennedy
