indication unless associated with a magnetic structure.
2.
The instrument will not respond to nonmetallic materials such as gold, silver, copper, brass and
aluminum.
MAINTENANCE
The GA-92XT is designed and built to give trouble-free operation. Normally, maintenance is limited to the
occasional replacement of the batteries. In the event a malfunction does occur, refer to the Troubleshooting
Guide on page 16 for a few problems that you can correct in the field.
Replacement of Battery
The GA-92XT is powered by one 9-volt lithium battery that has a shelf life of ten years, and provides twice
the operating life of an alkaline battery. The battery is located in the handle of the instrument and can be
accessed by turning the screw counterclockwise by hand or with the use of a screwdriver or coin. To
remove the battery, simply tilt the unit so that the handle is pointing down, and the battery will slide out.
When replacing the battery, look at the inside of the battery door for the proper battery orientation. (The
positive terminal should be on the right on the inside of the unit) As a safety measure the unit has been
"Keyed" so that the battery will only make contact when in the correct orientation.
For this reason you
should never have to force the battery door closed. If the battery does not seem to be going in all the
way, remove, reverse and then replace.
CAUTION
The locator is shipped with a spare lithium battery conveniently stored in the
carrying case. It is recommended that when you use the spare battery you
replace it as soon as possible so that you will never be without a spare
battery in the field.
