4. BASIC OPERATION AND DESCRIPTION
4.1 Power On/Off Switches
Press “ON” once to activate the locator circuitry. Press “OFF” once to turn the battery power off.
4.2 Volume and Sensitivity Control Knobs
Rotate the volume knob to the desired audio volume level. Full volume is achieved when the knob is turned fully
clockwise.
The sensitivity or depth range can be varied using the sensitivity knob. Maximum range is provided at full
clockwise rotation. The optimal setting is determined by each particular application. Areas crowded with various
undesired ferrous objects may require a reduced sensitivity level. Deeply buried objects being searched will require
a higher sensitivity level.
A decal with markings for both the sensitivity and volume control knobs is provided as a reference for future
settings or comparisons.
4.3 Speaker
When no ferrous metal is present, the audio sound heard will be a low frequency tone. As ferrous metals are
approached, the audio tone will increase.
4.4 LCD Visual Display
Several visual display functions, provided for ease of operation, are defi ned below:
“Ferrous”
Defi nes the basic function of the locator as a ferrous locator (fi xed indicator).
Digital Signal Indicator
A two digit numeric display shows the signal level as related to the audio signal response being heard from the
speaker. At the lowest signal level, when no ferrous metal is present, a small number will be viewed (between “0”
and “5”). As metal is approached, the numbers will increase, reaching “99” at its maximum peak. Deeply buried
objects or lower sensitivity levels will yield a lower peak number to aid in pinpointing the object.
Analog Bar-Graph Signal Indicator
The bar graph display expands outward from the center “diamond” as related to the audio signal response being
heard from the speaker.
