which direction had the highest radio signal level. Then switch the
Vecta™
3
from the NUMBERS display to the MICRO display, and place
the unit in a hand held searching position- in the direction of the highest
reading- immediately upon pushing the NUMBERS/MICRO key.
Scan the area a few degrees to the right and a few degrees to the left to
more accurately pinpoint the bearing that you want to proceed on. The
display will move up and down relative to beacon signal strength.
Proceed in the direction of highest signal.
Press the MICRO button again to return to NUMBERS display. See the
next Section and the Appendix for detailed information about the LCD
display.
Using a training beacon
To set the
Vecta™
3
to the frequency of the training beacon:

Read the frequency on the label of the training beacon

Using the Menu function, set the frequency of the unit to match the
beacon (see Appendix for details about using the display screen and
keypad)
Setting up the system on external power
To run the Vecta™
3
on an external power source use the 12VDC power
jack located on the end of the Vecta™
3.
See Figure 2, number 11 for
location.
UNDERSTANDING THE LCD DISPLAY
1. NUMBERS, BARS and MICRO
The NUMBERS screen and the BARS screen provide the same data in
two different forms. You can use either one or both, whichever works
best for you. Most people prefer the NUMBERS screen, thus it is the
primary screen. The MICRO screen magnifies the current signal level to
determine bearing more accurately. It does not cover the entire range of
signals that can be detected, and should be used as a “close up view”
but not be depended upon as the entire view.
WHAT THE NUMBERS MEAN: The further from the beacon
transmitter, the smaller the number. The closer to the beacon
transmitter, the larger the number (maximum of 999).
2. User interface structure
The Vecta™
3
has an LCD display that functions much like other
consumer electronic devices. Often used functions appear as buttons on
the unit. User preferences and setup are available via a menu, which is
accessed from a button, navigated via up/down buttons, and
preferences selected via a confirmation button. Below is a map of the
user interface structure (Figure 6). Also see the Appendix for more
details regarding the screens.
