Chapter 5 XLT

Pro Options

14. 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 positive +95 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 position, 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 over-written by the factory

recommended settings. Only the Custom Programs

will save your custom settings through Preset

Program selections.

Accepting certain V.D.I. numbers will have an

impact on detection depth, particularly for very

deep targets that are difficult for the display to

identify. Positive +95 is one of these V.D.I. num-

bers. Some Preset Programs are set so that the

positive +95 V.D.I. number is rejected. The display

uses positive +95 for many different types of

DISC. EDIT

+72

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 key-stroke rule in that

they do not have a graphic control knob.

However, ENTER must still be pressed

before adjustments are possible.

(Discrimination section)

Tips - The factory Preset

Programs have all the

major DISCRIMINATION

EDIT set-ups 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.
