I have both the CMOS II and the CMOS III. I run them both off of batteries,
and I have yet to change a battery. They are connected to the batteries
constantly. I don't use a regulator. The batteries connect directly to the
keyers. I use a little radio shack four cell AA battery holder. I use a
dummy battery (a short) in one of the battery positions. That puts 4.5 volts
on the keyers. My friends who have done the same say that the cells last the
shelf life of the batteries, and I sure believe it. Changing the batteries
every couple of years is hardly a chore, and beats reprogramming!
