BATTERY INSTALLATION AND REPLACEMENT

• Replace the battery if the Power Indicator (3) does

NOT light when 94dB/114dB/Off Slide Switch (4)

is in the 94 dB or 114 dB position and/or when there

is no audible tone.

• Unscrew the Battery Compartment Ring (5).

• There are wires connected to the Battery Compart-

ment (6), so SLOWLY lift the center to access the

battery.

• Insert a fresh 9V Alkaline battery.

• Replace the Battery Compartment (6) and tighten

the Battery Compartment Ring (5).

• A fresh Alkaline battery should power your calibrator

for approximately 20 hours of use.

• Remove the battery if the calibrator will not be in

use for a long period of time.

• Tampering with the internal circuitry will void your

warranty.
