AUDIO CHOICES
Belltone
Garrett's Coin Alert Belltone ™, which is
the factory Audio setting for the GTI , will
signal the operator with a special ringing
sound whenever a target of high con-
ductivity (first nine segments from right
on the Upper Scale), such as a coin, has
been located. Other acceptable targets will
cause an audio increase.
If you wish to use the Belltone audio
enhancement for target sounds, no action
is necessary at factory settings. To turn
off this function use MENU to display the
word, press and the letters will begin
blinking. Pressing (+) will turn it back on.
Bi-Level
Two distinctly different types of sound
are produced when the Bi-Level audio
enhancement is being used. Targets of
higher conductivity produce a higher-
pitched sound. Targets of lower conductivi-
ty (the Iron/Bottle cap range on the Target
ID Guide) are identified with a sound that
is pitched slightly lower.
