12TURNING THE DETECTOR ON

13

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).

Overloading is not harmful to the electronics of the detector.

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 X-Terra 70 can save separate settings for each mode. When a mode has been selected, the menu settings that have changed will flash 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 flash for three seconds.

If Sensitivity is adjusted to 16 in Prospecting Mode, the Sensitivity icon will not flash when changing modes.

(Menu Operation, pg. 28).

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.
