camcorder batteries. You can obtain additional batteries of this type from

test equipment and/or video camera accessories.

Removing the Batteries

To remove the batteries, use the following procedure:
1 Turn off the Counter, and disconnect all external cables (including the
power cord).
2 Turn the two thumb screws that secure the battery sled to the Counter's
back panel counterclockwise until both thumb screws are completely out
of the threaded holes in the back panel (see Figure C-3).
