Replacing the Batteries

Counters equipped with the Battery option use sealed lead-acid VHS camcorder batteries. You can obtain additional batteries of this type from Agilent (Agilent P/N 53150-80010) and from other suppliers who carry test equipment and/or video camera accessories.

Removing the Batteries

To remove the batteries, use the following procedure:

1Turn off the Counter, and disconnect all external cables (including the power cord).

2Turn 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).
