Battery Gauge
The scale at the lower right of your GTI
2500 's screen will indicate accurately the
condition of standard (carbon or alkaline)
or rechargeable batteries.
To switch from the standard batteries to
the optional rechargeable batteries, use
MENU to scroll to the battery icon. Pressing
the (+) or (-) keys will select either stan-
dard or rechargeable batteries. The GTI
2500 has dual scales to display an accu-
rate indication of either standard (carbon
or alkaline) or rechargeable (nickel metal
hydride or NiCad) battery life. If you select
rechargeable batteries, be sure to load the
GTI 2500 with the appropriate batteries.
