At any time, the display screen indicates the current category notches or discrim-
ination settings. Any category whose description is not visible will not be detected.
For example, the following settings tell us that:
• The nickel, dime,
quarter and 50¢
categories will be
detected.
• All other categories
of targets (iron, foil,
alum and zinc) will
not be detected.
4. VOLUME
While the VOLUME line is highlighted, use and to change the
speaker volume.
The default volume setting is 8. Maximum is 10.
Minimum is 0 (volume off). At levels 1, 2 and 3, high tones will be inaudible or
barely audible.
The speaker volume will diminish as battery voltage drops. For maximum
speaker volume, use 1 or 2 tones, as the low and bass tones generate the
loudest sounds.
Volume can be set while in either the DISCRIMINATION or ALL METALS
modes, but only one setting applies to both modes. Volume in the two modes
cannot be set independently.
