Sensitivity Adjustment - Outbound 079-4100-2 Manuel D'utilisation

SENSITIVITY DJUSTMENT
Upon power-up, the detector defaults to 3/4 sensitivity. To increase to full
sensitivity, press the Sensitivity L touch pad.
ELECTROM GNETIC INTERFERENCE
The principle use for the Sensitivity Control is to eliminate
electromagnetic interference (EMI).
A hobby metal detector is an extremely sensitive device; the searchcoil
creates its own magnetic field and acts like an antenna. If your detector
beeps erratically when the searchcoil is motionless, the unit is probably
detecting another magnetic field.
Common sources of EMI are electric power lines, both suspended and
buried, motors, and household appliances like computers and
microwave ovens. Some indoor electronic devices, such as dimmer
switches used on household lighting, produce severe EMI and will cause
the detector to beep erratically. Other metal detectors also produce their
own electromagnetic fields, so if detecting with a friend, keep two metal
detectors at least 20' (6 m) apart.
If the detector beeps erratically, reduce the sensitivity by pressing the
Down-Sensitivity Arrow M on the left of the control panel.
SEVERE GROUND CONDITIONS
A secondary use for the Sensitivity Control is to reduce false detection
signals caused by severe ground conditions. While your Outbound™
Metal Detector contains circuitry to eliminate the signals caused by most
naturally-occurring ground minerals, 100% of all ground conditions
cannot be anticipated. Highly-magnetic soils found in mountainous and
gold-prospecting locations can cause the detector to emit tones when
metal objects are not present. High saline content soils and sands can
also cause the detector to give a false reading.
If the detector emits false, non-repeatable, signals, reduce the sensitivity.
MULTIPLE T RGETS
If you suspect the
presence of deeper targets
beneath a shallower target,
reduce the sensitivity to
eliminate the detection of
the deeper targets, in order
to properly locate and
identify the shallower
target.
