HOW TO WORK THE CONTROLS

POWERING UP

Press 

• The detector always starts up with the DISCRIMINATION feature active.

Motion is required to detect metal.

• Sensitivity is at 70% of maximum
• All target categories are illuminated, meaning that all metal objects will

be detected.

OPERATION and CONTROLS

MENU SELECTIONS

1. DISC

Use 

and

to increase or decrease DISCRIMINATION level.

Each time you press 

, a target category is eliminated from detection.

Elimination occurs from left to right. When a category description (for example
“IRON”) disappears from the display, then targets classified in that category
will not be detected.  

Pressing 

reverses the discrimination process. With each press of

, a category description will reappear, indicating that targets

classified in that category will again be detected.

Discrimination is a cumulative elimination system.  Targets can be eliminated
from left to right on the scale, with each additional press of 

, resulting in

more objects being eliminated from detection.

2. NOTCH

Press 

until “NOTCH” is illuminated on the display.

Use 

and 

to notch target categories IN or OUT while the NOTCH line

is highlighted.

Whereas the discrimination feature eliminates all categories sequentially from
detection, the NOTCH control allows you to selectively include or exclude
target categories from detection.

With each press of 

or 

, the notched category moves across the

display screen.  As you move the position of the notched category, you are
changing the detection status of the selected category.

• If a target category was previously eliminated (word not visible) then

notching that category will return it to detection. 

• If a target category was previously retained (word is visible) then

notching that category will remove it from detection. 

Only one target category at a time can be selected for notching.  To notch
multiple categories in or out, press 

again while NOTCH is

highlighted. Each subsequent press of 

allows you to set an additional 

notch. Each time you press 

, followed by 

, the notch

program will begin by changing the status of the IRON segment.

At any time, the display screen indicates the current category notches or
discrimination settings.  Any category whose description is not visible will not
be detected.
