WARNING: The altitude calculated by the 400W-series 
is geometric height above mean sea level and could 
vary significantly from altitude displayed by pressure 
altimeters in aircraft. 
 
WARNING: The Jeppesen database incorporated in 
the 400W-series must be updated regularly in order 
to ensure that its information is current. Updates are 
released every 28 days. A database information packet 
is included in your 400W-series package. Pilots using 
an out-of-date database do so entirely at their own 
risk! 
 
WARNING: VNAV is to be used for advisory purposes 
only.  VNAV messages or vertical speed required should 
not be used to maintain terrain or ATC clearances.  Ter-
rain and ATC clearances are the sole responsibility of 
the pilot. 
 
CAUTION: The Global Positioning System is operated 
by the United States government, which is solely re-
sponsible for its accuracy and maintenance. The system 
is subject to changes which could affect the accuracy 
and performance of all GPS equipment. Although the 
Garmin 400W-series are precision electronic NAViga-
tion AIDs (NAVAID), any NAVAID can be misused or 
misinterpreted and therefore become unsafe. 
 
CAUTION: Use the 400W-series at your own risk. To 
reduce the risk of unsafe operation, carefully review 
and understand all aspects of this Owner’s Manual and 
the Flight Manual Supplement, and thoroughly practice 
basic operation prior to actual use. When in actual use, 
carefully compare indications from the 400W-series to 
all available navigation sources, including the informa-
tion from other NAVAIDS, visual sightings, charts, etc. For 
safety, always resolve any discrepancies before continu-
ing navigation. 
 
CAUTION: The electronic chart is an aid to naviga-
tion and is designed to facilitate the use of authorized 
government charts, not replace them. Land and water 
data is provided only as a general reference to your 
surroundings. The positional accuracy of the land and 
water data is not of a precision suitable for use in 
navigation and it should not be used for navigation. 
Only official government charts and notices contain 
all information needed for safe navigation – and, as 
always, the user is responsible for their prudent use. 
 
CAUTION: The Terrain feature is for supplemental 
awareness only. The pilot/crew is responsible for all 
terrain and obstacle avoidance using information not 
provided by the 400W-series Terrain feature. 
 
CAUTION: The Garmin 400W-series does not contain 
any user-serviceable parts. Repairs should only 
be made by an authorized Garmin service center. 
Unauthorized repairs or modifications could void your 
warranty and authority to operate this device under 
FCC Part 15 regulations. 
 
CAUTION: GPS receivers operate by receiving and 
decoding very low power radio signals broadcast by 
satellites. It is possible that in some situations other 
radio equipment or electronic equipment used in close 
proximity to a GPS receiver may create electromagnetic 
interference (EMI) which may affect the ability of the 
GPS receiver to receive and decode the satellite signals. 
In such event, the interference may be reduced or 
eliminated by switching off the source of interference 
or moving the GPS receiver away from it. 
 
NOTE:  The GNS 400W-series units use a different 
database than in the legacy units. The databases are in-
compatible between units. The GNS 400W-series units 
must use a  WAAS enabled database. 
 
NOTE:  This product, its packaging, and its components 
contain chemicals known to the State of California to 
cause cancer, birth defects, or reproductive harm. This 
notice is being provided in accordance with California’s 
Proposition 65. If you have any questions or would like 
additional information, please refer to our website at 
www.garmin.com/prop65. 
 
NOTE: It is the pilot’s responsibility for initial missed 
approach guidance in accordance with published pro-
cedure. The unit may not provide correct guidance until 
established on a defined leg. 
 
NOTE:  GPS level of service annunciations (LPV, ENR, 
etc.) are not applicable to the external CDI (or HSI) 
when VLOC is active.
