Checking transmission
WARNING:
The radar scanner transmits electromagnetic energy. Ensure
that the scanner has been installed according to the
recommendations given in Chapter 1, and that all personnel are
clear of the scanner, before switching to transmit mode.
Run through the radar operations described in the display unit
Owner’s Handbook and check that all the expected data is displayed.
Bearing alignment
When the system is correctly installed, you must check the bearing
alignment to ensure that targets appear at their correct bearing relative
to the ship’s bow, and adjust the alignment if necessary.
Display timing adjustment
The display timing can be affected by the length of the cable used to
connect the scanner to the display unit. This in turn affects the short
range accuracy shown on the display.
It is advisable to check the display timing before using the system for
navigation.
72" open array position alignment
To ensure the 72" open array scanner rests in correct position when
rotation stops, you need to adjust the radar set up as follows:
1. With the display switched on in Radar mode, press MENU then
press the RADAR SET UP soft key.
2. Use the cursor to select the ANTENNA SIZE option, then press the
6 ft softkey.
press ENTER twice to return to the default display.
If the Radar Set Up menu option ANTENNA SIZE is not available,
then you have an older version of display software. The 72" open
array scanner will operate correctly with this display. However,
for details on adjusting the open array stopping-position, please
contact your authorised Raytheon dealer or distributor.
