11. CUSTOMIZING YOUR UNIT
This difference is called magnetic variation, and varies with respect to the observation
point on earth. Your unit is preprogrammed with all the earth's magnetic variations.
However, you may wish to enter variation manually, referring to a nautical chart, to re-
fine accuracy. Set to [AUTO] to get correct variation when there is no position data.
[INTERNAL GPS SETUP]: Set up the internal GPS receiver.
[RESTART GPS]: Restart reception of GPS satellites.
[NAVIGATION SPEED]: Set different dynamic platform models to adjust the naviga-
tion engine to the expected application environment. [Low] corresponds to pedestrian
dynamic platform model. For applications with low acceleration and speed. [High] cor-
responds to at sea dynamic platform model. Recommended for applications at sea.
[DIFFERENTIAL CORRECTION]: Turn GPS differential correction on or off. The cor-
rection is made with SBAS (WAAS, EGNOS, MSAS).
[GPS SIMULATION]: Set up the GPS simulator.

[SIMULATION MODE] activates or deactivates the GPS simulation mode. Set the
course, speed, date and time. [CURSOR CONTROL] allows control of the simulation
speed and course with the arrow keys. Use the up and down arrows to control speed;
the right and left arrows to control course.
[FISH FINDER SIMULATION]: Activate or deactivate the fish find simulator. [Demo1]
is a shallow water simulator and [Demo2] is a deep water simulator.
