Raymarine Chartplotter RL70CRC PLUS, RL80CRC PLUS, Combined Pathfinder Radar Radar Display Timing

8-20 hsb2 PLUS Series Color LCD Display

Incorrect timing is most noticeable on the 1/8 nm or ¼ nm range scales. Targets such as bridges or piers appear bent or bowed.

Note: Under normal circumstances you do not need to adjust these settings, as

they are set automatically at the factory. If these parameters are set

incorrectly the performance of the radar will be adversely affected.

Access to this menu is therefore via a hidden key press.

➤To adjust for correct timing:

1.Select the 1/8 nm range.

2.On the radar locate a straight dock, seawall or bridge that is facing your ship. If the image is bent or bowed, as shown in the following diagram, then you need to adjust the timing.
