9 DELEÓN OPERATOR INSTRUCTION MANUAL
Start with the controls as shown in the photo below:
1) THRESHOLD, SENSITIVITY and DISCRIMINATE LEV-
EL knobs turned completely counterclockwise.
2) MODE switch in the DISC setting.
Check Display Readings in DISC Mode
Turn the SENSITIVITY knob from OFF to about 2-3. In the first
couple of seconds, you may or may not hear a slight hum that will fade
away and the display will read TESORO, DELEON and DISC. As long
as these three screens show up, you can be assured that your DeLeón has
started up properly.
