Accept/Reject Pushbutton

(Use in conjunction with the DISCRIM
pushbuttons to modify the discrimination pattern.)
Press the Accept/Reject pushbutton to eliminate or activate
pixels located on the Lower Scale, directly below the Target
ID cursor.
As seen in the illustration below, the ACE 350 has 12 pixels
or "notches" of discrimination. Any combination of these
pixels can be switched on or off based upon your preference.
There are two primary methods for modifying the Notch
Discrmination Pattern to reject a specific type of trash or
unwanted item while detecting all other metal.
The example below illustrates how to manually use both
the DISCRIM and Accept/Reject pushbuttons to modify the
Notch Discrimination pattern.
Use the DISCRIM buttons to position the Target ID Cursor above the pixel you
wish to eliminate (see above illustration). Use the Accept/Reject pushbutton
(/X) to delete this pixel from the Lower Scale (see below). This item is now
rejected.

The second method of modifying the Notch Discrimination
pattern involves the use of only the Accept/Reject
pushbuttons. When an unwanted metal target is audibly
detected while hunting, simply push the Accept/Reject button
to create a notch where the Target ID Cursor has signaled the
presence of the trash. The next time the ACE 350 encounters
the same trash item, it will not produce an audible signal.
The ACE 350's Accept/Reject pushbutton (/X) can also
be used to find specific metal items. For example, if an
earring has been lost, scan the matching earring with the ACE
350 while in the ZERO mode. Note where the Target ID cursor
appears when the earring is scanned. Next, use the DISCRIM
and Accept/Reject pushbuttons to switch off all the pixels
except the one for the earring.
Note: Depending upon how the lost earring is laying in the
ground, its Target ID may shift a little; therefore, your ability
to find it will be enhanced by turning on an additional pixel
on either side. The ACE 350 is now programmed to find only
the missing earring based on the conductivity of its matching
pair.
Note: The accept/reject function can be used to modify
each Mode's discrimination pattern. Notch Discrimination
modifications made while in CUSTOM mode will be retained
when the detector is turned OFF. However, all changes made
to the Notch Discrimination pattern while in ZERO, JEWELRY,
RELICS or COINS modes will return to the factory settings
when the detector is turned OFF and back ON again.
