Section 3 Operation
MAGNETIC CORR. (Correcting the magnetic compass)
•In this menu, you can set a correction value for the magnetic variation
automatically (AUTO) or manually (MANUAL). The readout of the
bearing will be the sum of the input bearing data and the correction
value. You can select AUTO or MANUAL for setting the correction
value. For example, enter E7.0° as the correction value when the
magnetic variation currently listed in the marine chart is W7.0°. The
correction range from 0.0 to W99.9° or E99.9°, and you can set it in
increments of 0.1°. To disable correction, select MANUAL and set the
correction value to 0.0°.
Note:
•A magnetic variation value set with AUTO is a rough value calculated
based on the current date and time, and the ship’s current position. You
cannot set it with AUTO if the data of the current date & time and the
current ship’s position is not stored. When it is necessary to set a more
precise value or when the abovementioned data is not stored, set it with
MANUAL.
RESET LOG (Resetting the trip log)
•In this menu, you can reset the LOG value to “0”. The LOG is the
sum of the navigated distances and displayed at the top of the screen
in the NAVIGATION mode. The value of the LOG is maintained
after the RADAR 1800 is turned OFF.
