4.20 TARGET EXPANSION
Target expand mode can be set to “on” or “off”. When “on”, this function in-
creases the size of the displayed images to make small targets appear larger and
easier to view on screen. When active,“EXP” is highlighted in the upper left
area of the screen.
4.21 INTERFERENCE REJECTION
OPERATION
Interference Rejection (IR) mode can be set to “on” or “off”. The IR reduces
“noise” on the display caused by other radars. When active, the “IR” is high-
lighted at the upper left of the screen. If you are navigating in a port area ser-
viced by a RACON, you should turn off the IR mode in order to see the RA-
CON signals clearly.
4.22 DISPLAY MODE
Targets can be displayed in black on a white background, or vice versa.
4.23 PLANNED-TX MODE
The PLANNED-TX mode allows the operator to program the radar automati-
cally to transmit for a pre-determined length of time, followed by a stand-by
period.
This maintains a radar watch whilst reducing the power consumption experi-
enced during full transmit operation. In PLANNED-TX mode press the STBY/
OFF key and the radar will return to its normal operating mode.
If you’ll watch the RADAR BEACON and the SART, set the pro-
cess as follows.
IR OFF
CAUTION
