Tesoro Outlaw Operator's Instruction Manual page 14

The ground balance setting is extremely important when the mineral conditions in the ground
are strong enough to affect the Outlaw Metal Detector. (See the Field Use Section on ground
balancing for actual use.)
The ground balance is not important for the air-test, so this step is done before the unit is
turned on.
Turn the Ground Balance (GROUND BAL) knob one full turn counterclockwise. (e.g. if the knob
pointer was at the 12:00 position, turn the knob one direction until the pointer is at the 12:00
position again). Notice that there was no stop on the knob. The plus (+) and minus (-) on the
decal indicate a direction, not a position. Turn the knob one more full turn in the
counterclockwise direction. There is still no stop on the knob. The potentiometer (pot) inside
will turn 3 and ¾ turns before the internal adjustment ends. When the inside of the pot stops,
there may be a slight increase in the drag on the knob as it continues to turn. This will not cause
any harm to the pot. Turn the knob one full turn clockwise. Don't adjust this knob again for the
remainder of the air test.
Now you should understand that the ground balance knob will have a different feel than the
other knobs.
Step 2 – Perform an Audio Battery Test
When the unit is first turned on, the Outlaw Metal Detector will automatically activate the audio
battery test.
Turn the SENS control from OFF to 1.
