Example misaligned radar
Target object dead ahead
(bearing alignment will be required)
D11590-1
Radar target not aligned
Checking the bearing alignment
1. With your vessel under way: Align the bow with a stationary
object identified on the radar display An object between 1 & 2
NM distant is ideal.
2. Note the position of the object on the radar display. If the target
is not under the ships heading marker (SHM), there is an
alignment error and you will need to carry out bearing alignment
adjustment.
Adjusting the bearing alignment
Once you have checked the bearing alignment you can proceed and
make any required adjustments.
With the radar page displayed:
1. Select the bearing alignment menu.
2. Press the BEARING ALIGNMENT softkey.
3. Use the rotary control to place the selected target under the
Ship’s Heading Marker.
4. Press OK when complete.
Adjusting radar offset (parking)
This setting is applicable to open array scanners. It is used to
ensure the scanner parks in the correct position when rotation stops.
Before you proceed, ensure that:
• The radar page is selected
• The radar scanner is initialized standby mode
1. Press the MENU button and then select the radar setup menu
(with the radar in standby mode).
2. Select the PARKING OFFSET option, then adjust the offset
angle required to park the radar so that the antenna comes to
rest facing forward (you should see the Raymarine logo wording
from the front of the vessel) when you place it in either standby
or switch it off.
3. Press OK when complete.
