Switch on and initial set up
On the digital radar, ensure the power switch is set to ON. Switch on
the display unit. The magnetron warm-up sequence should start, after
which the unit should enter Standby mode. If necessary, adjust the
lighting and contrast. If required, change the default language
settings.
Checking transmission
WARNING:
The radar scanner transmits electromagnetic energy. Ensure that the
scanner has been installed according to the recommendations given,
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, (see
display unit
Owner’s Handbook for information on bearing alignment).
Display timing adjustment
The display timing setting can be used to set/change the range
accuracy shown on the display, if required. It is possible to check the
display timing before using the system for navigation. To fine tune the
radar for accuracy if required see your display unit
Owner’s
Handbook
