CONTROL PANEL
The operating controls are as follows:
SENSITIVITY + ND –
These controls change the detector's sensitivity; higher
settings enable detection of deeper targets. At power-
up, the detector is pre-set to 75% of maximum
sensitivity. At minimum, the sensitivity is 35% of
maximum. With each press of the + or – touch pads,
the sensitivity level is displayed on the bar graph on the
left of the display. Upon reaching the minimum or
maximum sensitivity setting, the detector will beep
twice.
While higher levels of sensitivity enable detection of deeper targets, operation at
high levels of sensitivity make the detector more susceptible to electromagnetic
interference. Higher sensitivity settings can also lead to false signals in difficult
ground conditions. Use lower sensitivity settings to suppress interference or false
signals from soil minerals when necessary.
If the detector "Chatters", reduce sensitivity.
UTO TUNE ( ll Metal)
Press this pad and "ALL METAL" appears on the display
This mode is a ground-balanced All Metal motion
search mode. This mode offers the maximum
amount of sensitivity under most ground conditions.
The searchcoil must be in motion to detect metal.
One monotone sound is emitted. No discrimination
or target identification is possible in this mode.
Use the Sensitivity or Threshold controls to
change the sensitivity or background hum. Maximum sensitivity to buried
metal objects is achieved with a slightly audible background hum.
To achieve an audible background hum:
1. Press AUTO TUNE pad to enter this mode.
2. Press Sensitivity + or
This sensitivity setting may be the highest "quiet" setting, or you may hear
a faint background hum.
3. Press Threshold + or
The Sensitivity control works like a course adjustment in this mode.
The Threshold control works like a fine adjustment in this mode.
The AUTO TUNE Mode must be ground-balanced to eliminate interfering
signals from soil minerals. See the section on ground balancing for a
description of this procedure.
