DFX 300 Manual - White's Metal Detectors

Tips - If searching for one specifi c
target and an exact sample is available,
BLOCK EDIT everything for reject then
use LEARN ACCEPT to accept only
that specifi c target. If using a standard
program and a specifi c unwanted
trash target is being detected, use the
LEARN REJECT to change the program
to reject it.
CAUTION
If you do not return to the LEARN
selection screen and turn LEARN OFF,
the detector will continue to learn (AC-
CEPT or REJECT) every metal target it
encounters. Selecting LEARN OFF after
you have learned a target is extremely
important.
Iron alloys, such as steel bottle caps
or nails, should never be used for this
LEARN method of programming. Because
of their inconsistent V.D.I. indications,
iron alloys tend to scatter or otherwise
confuse the discriminate program.
If this occurs, it is best to turn the detector
OFF, back ON, and re-ENTER the
desired Program to return to the original
factory preset discriminate settings.

15-16. Learn Accept/Reject
Specifi c target samples can be used to show or
teach the discriminator what metal targets you
desire to ACCEPT or REJECT.
Select LEARN ACCEPT or LEARN REJECT with
the ARROW controls and press ENTER to turn
LEARN ON. The current selection is indicated by
the √ mark in square on the left of the display.
Once ON:
1. Squeeze and release the TRIGGER.
2. Show metal target sample or samples to
the instrument by sweeping them one at a
time in front of the loop until the desired
accept or reject sound is heard.
3. Press either ARROW control to return to
the LEARN selection display.
4. Press ENTER control to select LEARN
OFF.
5. Squeeze and release the TRIGGER to
return to a searching mode.
As with EDIT, LEARN changes will only be temporary
until saved in a Custom Program.
If LEARN has been used to develop a discriminate
program, the ACCEPT or REJECT V.D.I. numbers
can be reviewed by using the EDIT feature.
