easier to see what kinds of targets you are accepting and reject-
ing. Keep in mind that these are only potential target types, and
that many targets (especially jewelry) can have broad ranges.
The icons that are assigned to the VDIs depend on the pro-
gram selected. There are three pre-defined icon tables for Park ,
Relic , and Prospecting . These are shown on the next page. In
the factory programs, the Park icon set is used for all programs
except Relic and Prospecting.
Speaker and Headphones
VX 3 provides three ways to listen to audio:
• Speaker
• Plug-in headphones
• Wireless headphones
When you plug in a set of headphones, the speaker is disabled.
When wireless headphones are enabled and connected, the
speaker is disabled but plug-in headphones are still enabled,
allowing two people to use headphones for training purposes.
Basic wireless headphone connection was covered in Chapter 2;
see Chapter 8 for more detail.
Tip: There are 191 VDI numbers, and setting each one indi-
vidually can take a long time. There is a short-cut: when
you press the
ENTER button to check or un-check a VDI,
continue holding down the ENTER button, then press the 
or  button to rapidly set a range of VDI’s to the same set-
ting.
