When a target is detected in Auto Reject

entire Discrimination Pattern. This clears the
Smartfind Window, accepting all targets and
preparing the Window for learning a new
target.
Change the size of the cursor:
Press the Left Shift button to change the
Edit Frame size (Small, Medium, Large or
All Pattern).
To Auto Reject the target:
1 Place the target on the ground
2 Press the Right Shift button until the Auto
Reject Edit Mode is selected
3 Swing the coil several times over the
desired target until the detector rejects it
by filling an area in the Smartfind Window.
If you have more than one target, repeat
the procedure for each one

Button if you wish to load the pattern into

while in Edit will take you back to the
Discrimination Menu and all changes

The Combine Function

Combine allows you to merge preset or
saved Discrimination Patterns to create a new
Discrimination Pattern. The Combine function
should not be confused with how you select
Discrimination Patterns via the 'Select' Menu.
With Combine, you do not add or subtract
whole Discrimination Patterns. The 'white'
areas of a listed Discrimination Pattern are
what you accept or reject from the Combine
Discrimination Pattern.
The two Smartfind Windows at the top
of the Combine Screen are the Combine
Pattern (left) and the Active Discrimination
Pattern (right). The Active Pattern is the
Discrimination Pattern currently being used in
the Pattern/Digital Screen.
Combine Active
By default, the Combine Pattern (left
Smartfind Window) is empty. As you scroll
down the listed Discrimination Patterns, areas
of the Combine Pattern will flash relative to
the white areas of the selected Discrimination
Pattern. For example, if you select the
Jewellery Disc. Pattern, then the white area
of that pattern will flash in the Combine
Pattern. Each Pattern that is pre-programmed
into E-Trac is an 'accepting' pattern, i.e. the
Jewellery Disc. Pattern accepts Jewellery, the
Iron Disc. Pattern accepts Iron, etc. Therefore,
the 'flashing' area indicates where the object
is located.
