CALIBRATION/RESET:
1. Make sure that the Bottom Port of Vacuum Regulator is pointing down and away from direct
bright light. Use your finger to cover the Bottom Port Hole (see Figure 10).
2. With the Bottom Port pointing down and the Hole blocked, insert the tip of the tool into the
TEST hole and press until the Red CHECK LED on the Front Housing begins to flash rapidly. The
Amber BATT LED should come on first indicating that the batteries are good.

steps again.
