2. OPERATIONAL OVERVIEW
CAUTION
1. Prior to switching on the radar, make sure that no person nor obstacle is in the vicinity of the
scanner unit.
2. Because of hazardous radar energy, NEVER look into the beam of a transmitting scanner
radiator at close distance.
The Front Panel
The functional and user-friendly layout of the Control panel makes this radar easy and
instinctive to use. If you change a control setting you will see the associated reaction almost
immediately on the screen. Most touchpads carry abbreviated names to show their functions
and the same name appears on the screen for confirmation. (An illustration showing the
location and meaning of on-screen indications appears on page 2-3.)
Examine the display unit. All Controls are on the right-hand side, and the display is on the
left-hand side.
The uncluttered control panel contains the radar's most often used functions. Less often
used functions; for example, echo stretch, interference rejection and radar plotter, can be
accessed through the menu system (by pressing the
MENU
touchpad).
The
GAIN, A/C SEA,
and
A/C RAIN
Controls adjust the radar receiver. When pressed they
function as
HM OFF, PLOT,
and
FTC
switches, respectively.
Moving to the touchpad Controls, the
POWER
and
TX
touchpads turn on and off power and
transmit the radar. The
RANGE
-/+ touchpads select range.
The
SHIFT/ZOOM
(dual function),
RING, EBL, VRM, GUARD
and
MENU
touchpads turn on and
off their respective function.
The SHIFT/ZOOM touchpad alte mately enables the functions of shift and zoom.
The
GUARD
touchpad turns on and off the radar guard zone alarm.
The
MENU
touchpad displays the menu of sub-functions, including echo stretch, interference
rejection, and radar plotter.
The trackball, whose motion is followed by an on-screen cross hair cursor (hereafter called
cursor), operates the
EBL
and
VRM;
sets the guard zone; measures a target's range and
bearing, and selects the menu.
