At anytime during searching, this "ground balance sequence" may be repeated to ground balance the
Spectra to ignore ground minerals. The Spectra will automatically track to normal ground mineral changes. Quick
(abrupt) and dramatic (usually visible) ground changes may require a manual sequence such as dirt to gravel, dry
sand to wet salt sand, wood chips to dirt, sand to dirt, sand/dirt to rock, or other obvious ground changes.
• At initial turn-on, the Spectra begins in a general COIN & JEWELRY Program. This program provides
typical coin discrimination (reject iron and small foil, accept nickels and up). The Discrimination pattern is visible by
a color bar located across the bottom of the yellow/tan rectangle, RED representing rejected ranges, and GREEN
representing accepted ranges.
• If you have already been using the Spectra and have switched to a different Program, the Spectra
retains your preference and will begin in that Program (last used Program always returns regardless of battery
condition or installation).
• The Program in use is indicated on the center lower portion of the display.
cates that this is the original factory COIN & JEWELRY program, all settings are at the original default or SAVED
levels. A triangle in front of COIN & JEWELRY indicates there has been a recent change to the COIN & JEWELRY
program. (+/-) Behind COIN & JEWELRY indicates there is another program with the same name that has different
settings in the Library.
Backlight - On the same line as COIN & JEWELRY, to the far left, a light bulb indicates the display BACK-
LIGHT is on. Press "ARROW RIGHT" until Backlight appears highlighted on the far right bottom corner of display.
Press "ARROW UP" and "ARROW DOWN" to adjust the degree of backlight. Backlight will affect the ability to see
the display in all light conditions. At medium backlight settings 15% reduction in battery life is expected (a 1.5 hour
reduction out of ten hours use). At maximum backlight settings a 25% reduction in battery life is expected.
Live Controls - across the bottom of the display offer quick and easy "on the fl y" adjustment of all common
metal detector features. Use ARROW LEFT & RIGHT to highlight a feature, then ARROW UP & DOWN to adjust
it or ENTER to turn it ON/OFF. No need to enter a MENU. Adjustments are instant, like having knobs! Another
White's innovation.
VDI Numbers and Spectragraph "R" - Within the yellow / tan rectangle which dominates the display
important target indications are provided;
• A small target reference number scale VDI (Visual Discrimination Indication numbers) from -95-0-+95
are listed. -95 to 0 represents the negative (ferrous) or magnetic target range (most iron and steel). +1 to +95
represents the conductive (nonferrous) target range (most precious metals). The VDI number will vary depending
upon the exact characteristics of the metal itself. These VDI numbers are the same reference numbers the Spectra
uses to accept or reject different target types, especially important when customizing the Discrimination.
