Spectra VX 3 User’s Guide
Two keypad buttons have dual names. MENU/TAB is used
both as an entry button into the menu system, and to “tab” from
one screen area to the next. This tab method is identical to how
a PC interface uses it. So in some cases we will tell you to press
MENU , in other cases press TAB . It’s the same button. ZOOM/
VIEW works the same way. VX 3 also has four arrow keys, and
these may be either called UP DOWN LEFT RIGHT (or UP DN LT
RT ) or represented with the symbols  . Any of these
representations might be used.
Most menus are nested, so instead of telling you to press
MENU , then select the Audio menu, then select Search Audio ,
then select Discrimination , then select Modulation , we may
instead say, select MENU  Audio  Search Audio  Discrimina-
tion  Modulation . This means to drill down through the stated
menu path.
Finally, there is a trigger switch under the pod. It has a nor-
mal (center) position, a forward position, and a momentary
pulled position. When we say “pull the trigger,” we mean to
pull it to the momentary position and release it. If we say “Pull/
hold the trigger,” then pull it back and hold it there. This might
be in conjunction with a key press, such as, “Pull/hold the trig-
ger and press
ENTER ,” which is the same as “Trigger+ ENTER .”
Layout
The VX 3 interface consists of a keypad and a color screen.
The next page has a picture of the pod face with the default lay-
out for the search screen. The search screen has four major
regions:
1. Target information
2. SpectraGraph
3. Status Bar
4. Live Control Bar
The target information includes the “VDI” number, the depth,
and icons representing the likely target. SpectraGraph displays
