TONES: Variable Tone Selections
In Discrimination Mode, the Omega 8500 has 5 different pre-set tone variations
to choose from. See the table below detailing the settings of the 5 options.
Select the option that best suits your needs or conditions.
d4 and d5 Tone Options
These two settings give the most varied audio tones and are identical except for
one thing. The d5 Tone eliminates proportional audio and gives full audio
response to even the smallest signals. This option is often preferred when
searching for deep targets, enhancing the audio and making them very easy to
hear. The d5 tone option also affects the Multiple Target Category System (see
Target-ID Indicators
, page 23.) Normally, the primary Target-ID indicator Icon is
black and the secondary target indicators will be grayed-out or half-tone. In d5
tone setting, both primary and secondary Target-ID indicators will be solid black.
This will help when light conditions make it difficult to see the half-tone indicators.

until TONES menu become
enabled. Then use and to select desired tone option.
