Graphic Target Imaging 2500 - 77
BATTERY INFORMATION
The GTI 2500 is equipped with two battery
packs, each holding four (4) standard AA
batteries. The detector is also designed to
utilize rechargeable (NiMH) batteries. It is
recommended that top quality heavy duty
or alkaline batteries be used. It is advis-
able to remove the battery packs when
the detector is not in use, particularly for
a period of several weeks.
Although standard battery packs and
optional rechargeable packs can be used
interchangeably in the detector, it is rec-
ommended that both packs being used at
the same time always be the same type.
The GTI 2500 should search 25 to 30
hours with carbon, alkaline or high capaci-
ty rechargeable batteries. These estimates
are for speaker operation. Operating with
headphones will extend battery life.
