To prepare the equipment for use a heavy duty alkaline battery type 6LR61
should be fitted, such as a Procell/Duracell MN1604, Ever Ready 6LF22 Gold
Seal, or equivalent.
The battery door is located on the bottom left hand side of the instrument.
Open the battery door cover by sliding the cover downward towards the bottom
of the instrument. The cover will now swing open exposing the battery
compartment. Insert the battery observing the correct polarity as marked on
the case wall.
Close the battery compartment door by reversing the procedure above. The
instrument is now ready for calibration and use.
The microphone capsule fitted to your instrument is a class 2 instrumentation
grade 1/2 inch capsule.
The microphone assembly is not removable. The GA256 is fitted with a DOSE
meter microphone assembly in order that it can be attached to the collar of a
noise exposed worker.
