Notes 8 Apollo SL50/60 Features.
Getting Started the First Time This section explains how to get started using your Apollo SL50/60. Information in this section explains how to startup the unit, check signals from the GPS satellites, enter a seed position, and GOTO a destination waypoint.
Entering a Seed Position After the start up tests, you will always have the choice of entering a Seed Position. The Seed Position is a starting reference point so the GPS receiver knows what satellites it is looking for. If a Seed Position has been previously entered, you do not need to select a new Present Position or a Reference Waypoint.
2. Turn the Large knob to each character of the waypoint name. Change the character with the Small knob. aSLE c SALEM OR USA 3. Note that you can change the character just before the airport name to either a “c” or an “f.” The “c” indicates a “city” and the “f” indicates a “facility.
4. After entering the Seed Position, you will be prompted next to clear the active flight plan. Choose Yes or No with the Small knob. Press ENT to now continue normal operations.
Checking GPS Signal Strength The unit shows the GPS signal strength screen in the GPS Sensor function. Make it a habit to check this screen to make sure that the unit is properly tracking visible satellites before you fly. The Apollo SL50/60 requires signals from at least four satellites to calculate a 3D position fix (Lat/Lon and GPS altitude).
Note The GPS antenna must be able to “see” each satellite it is tracking. If a satellite is “shaded” by the wing or fuselage during a turn, it may temporarily lose track of that satellite.
Using the Direct-To Function 1. Press the Direct-To key. Change the waypoint type by moving to the character to the left of the waypoint name with the Large knob. vUBG f NEWBERG OR USA 2.
