TAKEOFF TOUR

The Garmin 400W-series provides you accurate 
navigational data and some models also have com-
munication capability, along with non-precision and 
precision approach certification in the IFR environ-
ment. 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 pro-
cedures 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 anten-
nas 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. 
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 Wel-
come 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. Informa-
tion on database subscriptions is available inside your 
400W-series package.
