For the strongest echo, a short afterglow lasts approx. 15 to 16 seconds and a long after-glow lasts approx. 1 minutes (62 to 63 seconds).

OPERATION 33

DISPLAY

* Displays the position of the own ship or waypoint in terms of latitude and longitude (L/L) or time difference

(TD).

*

Display the waypoint on the PPI screen.

Selects the unit of VRM or cursor range from

NM (nautical miles),

KY (kiloyards), and KM (kilometers).

*

Selects the type of bearing information that is to be used when display bearings.

Magnetic bearing : Receives the bearing information from an electronic magnetic compass.

Example: EMC-2

True bearing : Receives the bearing information from a gyro compass.

Selects EBL relative or true bearing.

Alternates between the transmission and standby (sleep) states for power saving.

Specifies the transmission time in terms of the rotational speed of the scanner unit.

Specifies the standby (sleep) time.

Functions identified by an "*"  require an optional unit or an external device.

RADAR SET-UP

Sets the guard zone alarm, sensitivity in terms of intensity of the echo image.

Sets the width of the transmitter pulses.

The narrower the pulse width, the better the range resolution is.

The wider the pulse width, the better the sensitivity is.

Selects the language for the text displayed on the screen.

4.28 DISPLAY OF RADAR TRANSPONDER

SART (Search and Rescur Radar Transponder) is life preserving device approved by GMDSS which is used for locating survivors in the event of a disaster or distress. SART operates in the 9 GHz frequency band. When it receives a radar signal (interrogating radio wave) of 9 GHz transmitted by a rescue ship or aircraft radar, SART transmits a series of respouse signals to the searchers to indicate the distress position.

In order to see the SART or radar beacon mark on the radar screen.

① RANGE SCALE : Select 6 or 12 nm.

② SEA : Set to minimum.

③ TUNE

④ IR

: DETUNED to reduce the clutter.

: Set IR OFF.

[EXAMPLE]

Attention

When above settings ① to ④ are made to display SART signals, objects around the own ship will not appear on the radar screen, so perform thorough visual monitoring of the sea area around the own ship to avoid any collision or stranding.

Further, when more than one radar systems are mounted, while using a 9 GHz band radar for searching SART signals, be sure to use another radar as an ordinary radar to perform monitoring of objects around the own ship to avoid any collision, check of the position of the own ship to avoid any stranding, and so on.

Need to retune the set for normal operation on completeion.
