BASIC OPERATION
■ Bearing setting
The radar bearing interface accepts NMEA, N+1, AUX,
or COG data format and the bearing can use a mag-
netic or true north type. When a true north type bear-
ing is used, the variation from magnetic north can be
adjusted on 0.1˚ steps.
D Setting the bearing type
q Push [MENU]/[ ], and then push [t] or [u] to
select the System menu.
w Push [p] or [q] to select the “Bearing Mode” item.
e Push [ENTER]/[ ] to enter the option selection
mode.
r Push [p] or [q] to select the Bearing mode.
• True and Magnetic north type are selectable.
• All displayed bearing readouts show the selected bear-
ing type.
t Push [ENTER]/[ ] to save the setting.
y Push [MENU]/[ ] to exit the Menu screen.
D Setting the magnetic variation
q Push [MENU]/[ ], and then push [t] or [u] to
select the System menu.

u Push [p] or [q] to set the bearing variation.
i Push [ENTER]/[ ] to save the setting.
o Push [MENU]/[ ] to exit the Menu screen.
* NOTE:
• NMEA data is required for the Auto variation. NEV-
ER select “Auto” without NMEA data or incorrect
variation data may be entered.
• Until an effective variation is received, use 0° for
difference between true North and magnetic North.
After an effective variation is received, use the last
data for the difference. The MR-1210 memorize
the data until you turn OFF the power.
