Power On The Garmin 400W-series provides you accurate navigational data and some models also have communication capability, along with non-precision and precision approach certification in the IFR environment. The Takeoff Tour is designed to familiarize you with the operation of the 400W-series - including powering up the unit, changing frequencies, entering data, performing a simple direct-to, selecting IFR procedures and provides a limited introduction to using flight plans. In addition, this section briefly covers the default navigation, map and frequency pages available as part of the NAV page group. These pages will be used for most of your in-flight navigation. The Takeoff Tour assumes that the unit and antennas have been properly installed and you have not changed any of the 400W-series unit default settings. If you have changed any of the factory default settings (position format, units of measure, selectable fields, etc.), the pictures shown here may not exactly match what you see on your 400W-series unit. Prior to using your unit for the first time, we recommend that you taxi to a location that is well away from buildings and other aircraft so the unit can collect satellite data without interruption. TAKEOFF TOUR Power On Powering up the 400W-Series Unit The 420W and 430W power and COM volume are controlled using the power/volume knob at the top left corner of the unit. The 400W power knob is located at the top left corner of the unit. Turning it clockwise will turn unit power on and increase the COM radio volume. After turning the unit on, a Welcome page will be displayed while the unit performs a self test, followed by the database confirmation pages which show the current database information on the NavData card (with the valid operating dates, cycle number and database type indicated). The database is updated every 28 days, and must be current for approved instrument approach operations. Information on database subscriptions is available inside your 400W-series package.
