13.6.3 How to calibrate NMEA 2000 data
You can apply an offset to NMEA 2000 depth, air temperature, water temperature and
speed through the water data to refine their accuracy.
1. Long-press the ESC/MENU key to open the menu.
2. Rotate the RotoKey
TM
to select [INTERFACE] then push the key.
3. Use the RotoKey
TM
to select [CALIBRATION] then push the key.
4. Select the data to calibrate then push the ENT key.
5. Use the RotoKey
TM
to enter the offset. Enter a minus value if the value is higher
than the actual value, or enter a plus value if the value is lower than the actual val-
ue. For example, if the actual water temperate is 75°F but the temperature indica-
tion is 76°F, enter -1.
6. Press the ESC/MENU key several times to close the menu.
