Pre-programmed Modes
There are two pre-programmed modes provided:
i) Meter Audio Disc
ii) Meter Disc
Meter Audio Disc
This is the recommended mode when starting to use the CS1220XD and is best demonstrated by
an air test (with the search head away from ground and all metal objects).
Turn the FUNCTION control (3) to METER AUDIO DISC (fully clockwise) and adjust the
SENSITIVITY control (2) to mid-position.
Turn the detector ON at the POWER ON/OFF TUNE control (1) which works in conjunction
with the RETUNE button (5). Hold the RETUNE push button down, and rotate the TUNE control
clockwise until the sound is just beginning to be audible. Set this carefully and precisely and then
release the RETUNE push button. If the tuning level alters or wanders off tune, do not adjust the
TUNE control. Simply operate the RETUNE push button which will automatically re-tune the
detector to the original selected level. The meter needle should be central when the RETUNE
push button is released.
The detector is now excluding ground minerals at a pre-set level and discriminating at a pre-
programmed level on the other channel.
All metal objects will be indicated by an increase in loudness but rejected objects will cause the
meter to fall to the left and the tone frequency to decrease. Accepted targets will conversely cause
the meter to rise to the right or remain stationery and the tone frequency to increase.
In this mode, the DISCRIMINATE controls and the GROUND control are not enabled.
