changes made with Combine will

be lost.

Discrimination Menu

To Combine Discrimination Patterns:

1 Press the Menu button

2 Scroll across to Discrimination (using the

Right or Left Navigation button)

3 Scroll down to Combine (using the Down

Navigation button)

4 Press either the Left or Right Navigation

button to enter the Combine list of Patterns

5 The two Smartnd Windows at the top of

the screen are the Active Pattern (right)

and the Combine Pattern (left). Press the

Left Navigation button to copy the Active

Pattern to the Combine Pattern

7 Once you have nished Combining, press

the Detect button (or QuickMask button

if you wish to load the pattern into

QuickMask)

8 Answer ‘Yes’ to the dialogue box to return

to the Pattern/Digital (or QuickMask) Screen

with your new Discrimination Pattern

loaded into Smartnd

6 Scroll down to the desired Pattern and

press the Accept/Reject button once to add

that Pattern to your Combine Pattern. Press

the Accept/Reject button twice to subtract

that Pattern from your Combine Pattern. A

third press will remove the Pattern from the

Combine Pattern

While a Discrimination Pattern is selected,

press the Left or Right Shift button to inverse

that pattern. The Accept/Reject button still

only modies the white area of the pattern.

For example, if ‘Coins’ is inverted, accepting

the pattern will accept the white areas,

therefore leaving you with an ‘all metal’

pattern. If the pattern is rejected, the white

areas are visible in the Combine Pattern, thus

creating a pattern that rejects everything

except the common Target IDs of coins.

Another useful feature of Combine is the

ability to compare Target IDs in both the

Active Pattern (right Smartnd Window) and

the Combine Pattern (left Smartnd Window)

simultaneously. If you detect a target while

in Combine a crosshair will appear in both

windows. By doing this you can see whether

your new Combine Pattern is rejecting a

desirable target, or accepting an undesired

target, and you can then modify your

Combine Pattern further to get the right

discrimination.

The Accept/Reject button is used to modify

the ashing area of a selected Discrimination

Pattern. The rst press accepts, the second

press rejects, and a third press cancels any

accepting or rejecting of that pattern applied

to the Combine Pattern.

It is important to plan how you will create

or modify a pattern using Combine, as the

last pattern accepted/rejected overrides any

previously accepted/rejected patterns if the

areas overlap. For example, if you reject the

‘All Metal’ pattern, then accept ‘Coins’ but

nish by rejecting ‘Crown Caps’, the area of

‘Crown Caps’ that overlaps ‘Coins’ will still be

rejected. Therefore, if you want to combine all

of these patterns you should apply rejected

patterns rst, and accepted patterns last.
