When a metal mass is detected, the alarm indicator provides a RED signal proportional to
the size (small/medium/large) or the distance of the object.
A dual-tone audio indication is also provided. The center of the target corresponds to the
tonal change.

2.5.1 Two-step localization procedure (Pin-Pointing)
When the device detects a target, the change of the alarm tone indicates the centerline of
an area where it is probably located.
To obtain a more precise localization, sweep with crossed axis in order to determine the
center point of the target.

2.5.2 Alarm Reset
The detector can trigger an alarm when placed near to a large size metal mass.
In this case, move away the detector from the metal mass: the alarm will reset
automatically. A prolonged alarm can be quickly reset, by pressing the ON/OFF button
briefly.
Do not reset the detector when placed near to a large size metal mass!
