Garrett Metal Detector GTI 1500 Owner's Manual page 62

Checking Condition
Battery condition is reported continuously
by the horizontal row of squares on the
lower right side of the screen. Five are vis-
ible when fully charged batteries are being
used. When only one square remains,
batteries should be changed. You should
always carry spares so that you will be
ready.
Rechargeable Batteries
When rechargeable batteries are being
used, the RECHARGE battery option must
be turned on for the battery level indi-
cator to be accurate. Continue pressing
the menu button to scroll to the battery
RECHARGE icon. Press (+) to set the
detector for rechargeable batteries. Press
(-) to set the detector for carbon or alka-
line batteries.
Replacement
1. Turn OFF the GTI 1500 by pressing the
POWER touch pad.
2. It is not necessary to remove the bat-
tery case. Just slide it back slightly from
its normal position beneath the armrest.
