SETUP INSTRUCTIONS
INSTALL BATTERY
The OS730K’s battery compartment (Fig. 1, Callout 4) is below the measurement trigger and
accessible from the front of the grip. Before installing the “9V” battery included in the
package, remove the plastic wrap covering its terminals.
To install the battery:
1. Open the battery compartment by placing your thumb and forefinger in the indentations
on the sides of the grip and pulling the top of the hinged compartment forward.
2. Plug the “9V” battery into the wired socket inside the compartment. The terminals of the
battery and the socket mate in only one way, with the smaller male terminal plugging into
the larger female terminal.
3. Close the battery compartment cover by pushing its top against the grip until the cover
snaps shut.
