Power On; Powering Up The 400W-Series Unit - Garmin GPS 400W Pilot's Manual & Reference

Power On

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
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. Informa-
tion on database subscriptions is available inside your
400W-series package.
