13. Disc. Edit
Allows for changing which targets V.D.I. or refer-
ence numbers are ACCEPTed (
detected
), or RE-
detected
detected
JECTed, (
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 tar-
get 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 Pro-
gram selections.
Accepting a wider range of V.D.I. numbers will
have an impact on detection depth, particularly for
very deep targets that are diffi cult for the display
to identify. Po95 is one of the most signifi -
cant 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

Will have a greater
impact on how the instrument operates
than any other feature. Audio Discriminate

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 ma-
jor DISCRIMINATION EDIT
setups already defi ned 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
specifi c or unusual targets
you may want to either AC-
CEPT or REJECT. Settings
from -95 - +95.
