Now that you have your unit installed, move on to Section 3, Basic So-
nar Operations. There, we'll present a series of step-by-step tutorials to
teach you the basics of how to operate your sonar.
NOTE:
When you first turn the unit on, the Map Page appears. If you'd
rather start learning about GPS operation first, turn over to Sec-
tion 6, Basic GPS Operations.
Face Cover
Your unit comes with a white protective cover that snaps on and off the
front of the unit. This cover is intended for use when the vehicle is idle.
WARNING:
When the unit is mounted in an unprotected area, such
as an open boat cockpit, the protective face cover must
be removed when the vehicle is moving at high speed.
This includes towing a boat on a trailer at highway
speeds. Otherwise, wind blast can pop off the cover.
