It is best to only turn the detector on,
when outdoors, away from sources
of electromagnetic disturbance.
There are many metallic objects inside
a house (e.g. nails in the floor,
reinforcing in the walls) that might
overload the electronics of the detector.
There may also be interference from TV
sets and other household appliances.
In this environment the detector may
perform erratically, giving numerous
false signals.
If the detector emits an overload sound
and displays OL on the LCD move
the coil away from the source of the
overload
(Error Messages, pg. 49).
Press
POWER.
A short start-up sequence will display
and a tune will be heard.
Once on, the detector will be in the
factory default Coin & Treasure Mode.
There will be no numeric reading
until a metal object is detected.

The Coin & Treasure Mode and
Prospecting Mode symbols will
appear throughout the rest of this
manual to indicate functions
specifi c to each mode only.
Overloading is not harmful to the
electronics of the detector.
Many of the screen diagrams in this
manual, that refer to features and
settings common to both modes, show
the Coin &Treasure Mode display only.
This illustration is a representation
of the LCD layout showing some of
the icons that appear during startup.
Please note that not all LCD icons are
displayed at the same time.
Detecting Modes
Before detecting, it is important to
understand that the X-Terra 70 can
operate in two different detecting
modes (Coin & Treasure Mode, pg. 18)
Prospecting Mode, pg.19)
.
The X-Terra 70 can save separate settings
for each mode. When a mode has been
selected, the menu settings that have
changed will fl ash for three seconds.
E.g. default Sensitivity is 16 in Coin &
Treasure Mode and 22 in Prospecting
Mode. When changing modes, the
Sensitivity icon will fl ash for three
seconds.
If Sensitivity is adjusted to 16 in
Prospecting Mode, the Sensitivity icon
will not fl ash when changing modes.
