To use the GBT 10 adapter, you must calibrate the position of the trim tabs the adapter is associated with.
 If you only adjust your trim tabs within a limited range of motion on a regular basis, calibrate the GBT 10 adapter using your normal
range instead of the full range. Only the calibrated range will be displayed on your chartplotter or marine instrument.

motion.
5. Enter the following command: “TRIMTABPOS=”
6. After the command, enter the percentage of the highest trim tab position as a whole number between 0 and 100, and select Done. For
example, TRIMTABPOS=0Done.
7. Move both trim tabs to the lowest position. When the trim tabs are in the lowest position, they should be at or near 100% of their full range of
motion.
