b. Discrimination
This range of functions allows you to reject or ignore unwanted signals generated by items such as pull tabs. It can
also act as "Notch Accept" or "Notch Reject". There are four options to set the discrimination level to give maximum
flexibility and ease of setting. A black block under the line of ID numbers indicates that a signal with that number will
give no audio sound but the ID display will still show the signal.
NOTE: Ensure that there is no other metal near the search head when setting the Discrimination by sweeping objects
over the head. It is also advisable to reduce the sensitivity slightly when setting the Discrimination using Learn Reject
or Accept to reduce the chance of any unwanted signals. Once set the sensitivity may be increased again.

In this mode the MENU/SCROLL control acts as a conventional Discrimination control. Turning the control clockwise
increases the discrimination level, as indicated by the black squares under the I.D. numbers on the display. Iron is to
the left (5 and below) and copper is to the right (15 and above). Sweep a sample of the item you want to ignore over
the search head while adjusting the control until it is rejected and press ENTER to store the setting.
NOTE: ID 0 (ground) cannot be cleared with this control. To alter ID 0 use DISCRIM EDIT (see below).

Learn Reject allows you to 'teach' the CSR1 to reject one or more targets that are swept over the search head. Once
Learn Reject is selected the sample or samples are swept several times over the head. The CSR1 will then set the
disc block at the sample ID point so that any objects with the same ID as the sample will be rejected.
TIP! This can be used as a Notch Reject facility. First use Discrim Set to accept all signals, and then use Learn
Reject to set the specific ID points of objects to be ignored.

Learn Accept allows you to 'teach' the CSR1 to accept one or more targets that are swept over the search head.
Once Learn Accept is selected the sample or samples are swept several times over the head. The CSR1 will then
clear the disc setting at the sample ID point so that any objects with the same ID as the sample will be accepted.
Care should be taken to ensure that you do not 'Learn Accept' ground, ID 0.
TIP! This can be used as a Notch Accept or Token hunting facility. First use Discrim Set to ignore all signals. Then
use Learn Accept to clear the specific ID points of the objects to be found.

This function enables you to set or reset the Discrimination at any desired point within the entire range. When this
function is selected, a flashing block (cursor) will appear under the 0 at the left hand side of the display. Pressing the
ENTER button will toggle the block at the current cursor position between ACCEPT and REJECT. Rotating the
MENU/SCROLL control will move the cursor. Rotate the control to the desired ID position and press the ENTER key
to either set (REJECT) or clear (ACCEPT) the block. When you have finished rotate the MENU/SCROLL control
clockwise until DONE is highlighted in the lower right hand corner of the display, then press ENTER.
