Fisher 1225-X - Manual (Page 6)

4
CONTROL FUNCTIONS
1. DISC: This control turns the power on and
automatically tunes the 1225-X for instant operation.
All types of metal are detected at the zero level
while the most pieces of trash are rejected at ten.
The DISC control has no effect when the PINPOINT
button is pushed in.
2. SENS: Normally set at ten, this control adjusts the
1225-X sensitivity to targets and ground minerals.
The higher the setting, the deeper you’ll detect.
However you will also pick up more false signals
in highly mineralized or trashy soil. In the extreme
counterclockwise position this control doubles as a
battery test. A loud tone indicates good batteries.
A faint tone indicates weak batteries and no tone
means that it’s time for a change.
3. HEADPHONES: This jack accepts most stereo and
mono headphones with quarter-inch diameter
plugs. If you use a stereo/ mono headset, make sure
it’s switched into the “stereo” position.
4. PINPOINT: When pushed and held, this button
switches the 1225-X into the Zero-Motion, All-Metal
Pinpointing mode.
