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.
