13. Disc. Edit
Allows for changing which targets V.D.I. or refer-
ence numbers are ACCEPTed (detected), or
REJECTed, (discriminated out) within the current
Program you are using.
Select DISC. EDIT and press ENTER. Now use
the ARROW controls to view the V.D.I. numbers
from negative -95 to po95 that appear on
the right side of the display. These are the same
reference numbers that are listed on the top right-
hand side of the control box (V.D.I. SCALE or
target chart). For each V.D.I. number, a
√
will
appear to the left indicating whether the current
program will ACCEPT or REJECT targets that
display that number.
Use the ENTER control to change any desired
V.D.I. number to ACCEPT or REJECT status.
If you do not save the entire Program into a Cus-
tom Program, the changes you make in EDIT are
only in use as long as you continue to use that
program. The only exception being the temporary
short-term or volatile memory as previously de-
scribed. If you make EDIT changes in Coin, and
then switch to COIN & JEWELRY, you lose all
editing you completed in the Coin Program. Each
time a factory Preset Program is ENTERed, all
unsaved settings are overwritten by the factory
recommended settings. Only the Custom Programs
will save your custom settings through Preset
Program selections.
Accepting a wider range of V.D.I. numbers will
have an impact on detection depth, particularly for
very deep targets that are difficult for the display to
identify. Po95 is one of the most significant
V.D.I. numbers. Some Preset Programs are set so
that the po95 V.D.I. number is rejected. The
display uses po95 for many different types

DISCRIMINATION - Will have a greater
impact on how the instrument operates
than any other feature. Audio Discriminate
ON/OFF is located in the BASIC
ADJUSTMENTS, (page 19).
DISC. EDIT and BLOCK EDIT are
exceptions to the keystroke rule in that
they do not have a graphic control knob.
However, ENTER must still be pressed
before adjustments are possible

Tips - The factory Preset
Programs have all the
major DISCRIMINATION
EDIT setups already
defined and ready for you
to use. Major changes in
ACCEPT and REJECT
targets should be selected
by choosing one of these
factory programs. EDIT
allows customizing for
specific or unusual targets
you may want to either
ACCEPT or REJECT.
