The first setup page is the system setup page, which

screen preferences. The GPSCOM 170 has three operat-
ing modes:
• GPS Off? disables all of the unit’s GPS functions
which will conserve battery power.
• GPS On enables all of the unit’s GPS functions,
making it a fully operational unit.
• Simulator? allows you to operate the unit without
acquiring satellites, and is ideal for practicing or
entering waypoints and routes while at home.
