If the unit switches to the Map Page or displays ‘2D’ or ‘3DNavigation’ during this process, it is not necessary to initialize the unit.The GPSMAP 162 will now begin searching for the appropriate satellites for your region and shouldacquire a fix within a few minutes. A signal strength bar for each satellite in view will appear on thetop middle of the page, with the appropriate satellite number under each bar. The progress of satelliteacquisition is shown in three stages:• No signal strength bars— the receiver is looking for the satellites indicated.• Hollow signal strength bars— the receiver has found the indicated satellite(s) and is collectingdata.• Solid signal strength bars— the receiver has collected the necessary data and the satellite(s)are ready for use.Once the receiver has collected information from at least three satellites, the top of the screen willdisplay either “2D or 3D Navigation”, and the GPSMAP 162 will be ready for use.Point to your approximate locationand press ENTER/MARK.A satellite’s signal bar will turn blackwhen it’s ready for use.Iwww.reelschematic.comwww.reelschematic.com
