BATTERIES
The GTI 1500 is equipped with two bat-
tery packs, each holding four () standard
AA batteries. (It is recommended that top
quality heavy duty or alkaline batteries
be used. The detector is also designed to
utilize nickel metal hydride (NiMH)
rechargeable batteries.) It is advisable to
remove the battery packs when the detec-
tor is not in use, particularly for a period
of a month or more.
Although standard battery packs and
optional rechargeable packs can be used
interchangeably in the detector, it is recom-
mended that both packs being used at the
same time always be the same type. The
GTI 1500 should search at least 18 hours
with carbon batteries and longer with alka-
line cells. Rechargeables should power the
detector approximately 20 hours on a full
charge. These estimates are for speaker
operation with the Backlight turned off.
Operating with headphones will further
extend battery life.
