Garmin aera 795/796 Pilot’s Guide
190-01194-00 Rev. C
Warnings, Cautions & Notes
WARNING: Navigation and terrain separation must NOT be predicated upon
the use of the terrain function. The aera 795/796 Terrain Proximity feature
is NOT intended to be used as a primary reference for terrain avoidance
and does not relieve the pilot from the responsibility of being aware of
surroundings during flight. The Terrain Proximity feature is only to be used
as an aid for terrain avoidance and is not certified for use in applications
requiring a certified terrain awareness system. Terrain data is obtained from
third party sources. Garmin is not able to independently verify the accuracy
of the terrain data.
WARNING: The displayed minimum safe altitudes (MSAs) are only advisory
in nature and should not be relied upon as the sole source of obstacle and
terrain avoidance information. Always refer to current aeronautical charts
for appropriate minimum clearance altitudes.
WARNING: The altitude calculated by aera 795/796 GPS receivers is geometric
height above Mean Sea Level and could vary significantly from the altitude
displayed by pressure altimeters. Always use pressure altitude displayed by
the aircraft altimeter when determining or selecting aircraft altitude.
WARNING: Do not use outdated database information. Databases used in
the aera 795/796 system must be updated regularly in order to ensure that
the information remains current. Pilots using any outdated database do so
entirely at their own risk.
WARNING: Do not use data link weather information for maneuvering in,
near, or around areas of hazardous weather. Information contained with in
data link weather products may not accurately depict current weather condi-
tions.
WARNING: Do not use the indicated data link weather product age to
determine the age of the weather information shown by the datalink weather
product. Due to time delays inherent in gathering and processing weather
data for data link transmission, the weather information shown by the data
link weather product may be significantly older than the indicated weather
product age.

Garmin aera 795/796 Pilot’s Guide
190-01194-00 Rev. C
Warnings, Cautions & Notes
WARNING: To reduce the risk of unsafe operation, carefully review and
understand all aspects of the aera 795/796 Pilot’s Guide documentation and
the Pilot’s Operating Handbook of the aircraft. Thoroughly practice basic
operation prior to actual use. During flight operations, carefully compare
indications from the aera 795/796 to all available navigation sources, including
the information from other NAVAIDs, visual sightings, charts, etc. For safety
purposes, always resolve any discrepancies before continuing navigation.
WARNING: For safety reasons, aera 795/796 operational procedures must
be learned on the ground.
WARNING: When installing the aera
™
795/796, place the unit so it does not
obstruct the field of view or interfere with operating controls.
WARNING: The indicators represented on the Panel are based on GPS-derived
data and may differ from the instruments in the aircraft.
WARNING: The United States government operates the Global Positioning
System and is solely responsible for its accuracy and maintenance. The GPS
system is subject to changes which could affect the accuracy and performance
of all GPS equipment. Portions of the Garmin aera 795/796 utilize GPS as a
precision electronic NAVigationAID (NAVAID). Therefore, as with all NAVAIDs,
information presented by the aera 795/796 can be misused or misinterpreted
and, therefore, become unsafe.
WARNING: The data contained in the terrain and obstacle databases comes
from government agencies. Garmin accurately processes and cross-validates
the data, but cannot guarantee the accuracy and completeness of the data.
WARNING: Do not use basemap (land and water data) information for
primary navigation. Basemap data is intended only to supplement other
approved navigation data sources and should be considered as an aid to
enhance situational awareness.

Warnings, Cautions & Notes
BATTERY WARNINGS:
If these guidelines are not followed, the internal lithium-ion battery may
experience a shortened life span or may present a risk of damage to the
GPS device, fire, chemical burn, electrolyte leak, and/or injury.
• Do not leave the device exposed to a heat source or in a high-
temperature location. To prevent damage, remove the device from the
aircraft or store it out of direct sunlight.
• Do not puncture or incinerate the device or battery.
• When storing the device for an extended time, store within the
following temperature range: from 32˚ to 77˚F (from 0˚ to 25˚C)
• Do not operate the device outside of the following temperature range:
from -4˚ to 131˚F (from -20˚ to 55˚C).
• Contact your local waste disposal department to dispose of the
device/battery in accordance with applicable local laws and
regulations.
Additional User-Replaceable Battery Warnings:
• Do not use a sharp object to remove the battery.
• Keep the battery away from children.
• Do not disassemble, puncture, or damage the battery.
• Only replace the battery with the correct replacement battery. Using
another battery presents a risk of fire or explosion. To purchase a
replacement battery, see your Garmin dealer or the Garmin Web site.
WARNING: Do not rely solely upon the display of traffic information for collision
avoidance maneuvering. The traffic display does not provide collision avoidance
resolution advisories and does not, under any circumstances or conditions, relieve
the pilot’s responsibility to see and avoid other aircraft.
WARNING: Do not rely solely upon the display of traffic information to accurately
depict all of the traffic within range of the aircraft. Due to lack of equipment, poor
signal reception, and/or inaccurate information from aircraft or ground stations,
traffic may be present that is not represented on the display.
CAUTION: Avoid using any chemical or abrasive cleaners on the touchscreen
and/or plastic casing. Clean the touchscreen with a soft, clean, lint-free cloth.
Use water, isopropyl alcohol, or eyeglass cleaner, if needed.

Warnings, Cautions & Notes
CAUTION: The Garmin aera 795/796 does not contain any user-serviceable
parts. Repairs should only be made by an authorized Garmin service center.
Unauthorized repairs or modifications could void both the warranty and the
pilot’s authority to operate this device under FAA/FCC regulations.
NOTE: The Garmin aera 795/796 has a very high degree of functional integrity.
However, the pilot must recognize that providing monitoring and/or self-
test capability for all conceivable system failures is not practical. Although
unlikely, it may be possible for erroneous operation to occur without a fault
indication shown by the aera 795/796. It is thus the responsibility of the pilot
to detect such an occurrence by means of cross-checking with all redundant
or correlated information available in the cockpit.
NOTE: All visual depictions contained within this document, including screen
images of the aera 795/796 panel and displays, are subject to change and
may not reflect the most current aera 795/796 system and aviation databases.
Depictions of equipment may differ slightly from the actual equipment.
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 web site at www.garmin.com/prop65.
NOTE: Use of polarized eyewear may cause the display to appear dim or
blank.
NOTE: Temporary Flight Restriction (TFR) data is provided by the FAA and
may not be updated outside of normal business hours. Confirm data currency
through alternate sources and contact your local FSS for interpretation ofTFR
data.

Charge the aera 795/796 for at least 4 hours before using on battery power. Charge
the battery by connecting the aviation power cable or the AC adapter.
Plug the unit into a 12-Volt or 24-Volt connector to charge. The unit can be used
while it is charging. Charge the unit within the following temperature range : 32° to
104°F (0° to 40°C).
Charging the unit’s battery using the aircraft's power outlet:
1) Mount the aera 795/796 in the aircraft and connect the power cable to the
aircraft power outlet (cigarette lighter receptacle).
2) Route the power cable so that it does not interfere with aircraft operation.
The unit begins charging as soon as external power is applied.
USING CHARGE MODE
Applying external power to the aera 795/796 automatically turns on the unit for full
operation. If the battery is present and needs to be charged, the external power source
charges the battery while the unit is in use.
If you do not want to use the unit, but you would like to charge the battery, you can
put the unit into Charge Mode. Connect the unit to an external power supply. Press
and hold the POWER Button. Instead of completely turning off, the unit now goes
into Charge Mode.
The unit will run cooler and may allow more current to be available while in Charge
Mode, when XM is unplugged, the backlight is turned down, etc.
