CONTROLS
Meter
The meter of the M-97 serves
two purposes for the opera-
tion of the instrument. When
used in the battery test mode,
the meter gives a visual indi-
cation of the battery strength.
A reading between 80 – 100
is desirable. If the reading is
below 80, search depth and
accuracy can decrease.
Please change the batteries, if
necessary. (Note: The batteries must be inserted correctly for the M-97 to
operate. Match up the correct battery terminals with the markings on the
inside of the battery holder. Failure to do so will not damage the instrument,
however, the instrument will not function).
When searching with the M-97, the meter gives a visual indication to any
change occurring in the field of detection. This is primarily due to the coil
passing over or near a metal object, but can occur when the ground
mineral conditions change.
On/Off Ground Rejection Control
This control turns the M-97 on and off. It is used to electronically balance the
M-97 to compensate for the natural mineral content of the soil or ground
surface. When tuned properly, raising and lowering the search coil above
the ground will not cause a change in the meter reading or audio tone.
Mode Switch
This control is used to change the mode function of the Locator.
Battery Test
With the detector turned on, the Battery Test mode will indicate
battery strength. This is a no-load battery test.
Normal
This setting is used for the Turn On and Go mode. The Normal
Mode requires very little Ground Rejection adjustment.
High
This setting is used for increasing the sensitivity of the M-97,which also
increases the depth searching capabilities of the instrument.
Retune Button
When this button is depressed, the instrument will rebalance itself to the
instrument settings and prevailing ground conditions.
