OVLY- Pressing the Overlay Key allows data from more than one
source to be displayed simultaneously on the display. Soft
Labels will indicate which data sources are available for
overlay.
SOFT LABELS
Soft Labels are located to the left of the Power Keys in the LCD area.
The description indicated in the label describes the key’s present func-
tion related to the displayed page. Whenever a new function is selected,
by pressing a key with a Soft Label, a new display is shown along with its
new key labels. This capability of displaying Soft Labels that are only
applicable to a particular screen is referred to as ‘Soft Keying’, and
allows one key to perform multiple functions without the complications of
multiple key presses on a conventional keypad.
JOYSTICK
This is a pointing device which moves a mouse-like pointer around the
display. It is primarily used for pointing at items on the map for further
information and for measuring range and bearing to specific points.
When the WX Radar function is selected, the joystick controls antenna
tilt angle and track. Data link weather also uses the joystick to perform
product display selection. It is also used to modify configuration settings
on the AUX setup pages.
CONTROL KNOB
The inner and outer Control Knobs, located in the lower right of the unit,
have various functions as indicated by a soft label when active. For
example, if the weather (WX) Function Select Key is pressed, the inner
knob may control the gain on the weather radar. The outer knob will act
as the radar function selector for ON, Standby (SBY) and Test (TST).
Data link weather also uses the joystick to do product display selection.
FAULT INDICATOR
The Fault Indicator is located between the Range buttons. If this tiny “F”
is illuminated, a system hardware problem is exists. This could be
caused by the unit failing a self test or an improper installation configura-
tion.
If the Fault Indicator appears, cycle the unit power. If the fault re-occurs,
the unit needs to be taken to an authorized service center to correct the
configuration or repair the unit.
