Warnings, Cautions, and Notes
WARNING: Navigation and terrain separation must NOT be predicated
upon the use of the terrain function. The GTN 7XX Terrain and HTerrain
Proximity features are NOT intended to be used as a primary reference
for terrain avoidance and do not relieve the pilot from the responsibility
of being aware of surroundings during flight. Terrain Proximity 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 GTN 7XX 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 GTN 7XX. 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.
WARNING: The altitude calculated by GPS receivers is geometric height
above Mean Sea Level and could vary significantly from the altitude
displayed by pressure altimeters, such as the output from the GDC 74A/B
Air Data Computer, or other altimeters in aircraft. GPS altitude should
never be used for vertical navigation. Always use pressure altitude
displayed by pressure altimeters in the aircraft.
WARNING: Do not use outdated database information. Databases used
in the GTN 7XX must be updated regularly in order to ensure that the
information remains current. Pilots using an outdated database do so
entirely at their own risk.
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.

WARNING: Do not use data link weather information for maneuvering
in, near, or around areas of hazardous weather. Information contained
within data link weather products may not accurately depict current
weather conditions.
WARNING: Do not use the indicated data link weather product age to
determine the age of the weather information shown by the data link
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.
WARNING: Never use datalinked weather to attempt to penetrate a
thunderstorm. Both the FAA Advisory Circular, Subject: Thunderstorms,
and the Airman’s Information Manual (AIM) recommend avoiding “by at
least 20 miles any thunderstorm identified as severe or giving an intense
radar echo.”
WARNING: For safety reasons, GTN 7XX operational procedures must
be learned on the ground.
WARNING: To reduce the risk of unsafe operation, carefully review and
understand all aspects of the GTN 725/750 Pilot’s Guide as well as this
guide. Thoroughly practice basic operation prior to actual use. During
flight operations, carefully compare indications from the GTN 7XX 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.

Warnings, Cautions, and Notes
WARNING: Traffic information shown on the GTN 7XX is provided as an
aid in visually acquiring traffic. Pilots must maneuver the aircraft based
only upon ATC guidance or positive visual acquisition of conflicting traffic.
Warnings, Cautions, and Notes
CAUTION: 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 GTN 7XX utilize GPS
as a precision electronic NAVigation AID (NAVAID). Therefore, as with
all NAVAIDs, information presented by the GTN 7XX can be misused or
misinterpreted and, therefore, become unsafe.
CAUTION: The GTN 7XX 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.
CAUTION: The display lens has a special anti-reflective coating that is
very sensitive to waxes and abrasive cleaners. CLEANERS CONTAINING
AMMONIA WILL HARM THE ANTI-REFLECTIVE COATING. It is very
important to clean the display using a clean, lint-free cloth and an eyeglass
lens cleaner that is specified as safe for anti-reflective coatings.
CAUTION: TFRs provided by datalink weather sources (i.e., FIS-B and
SiriusXM) are only advisory and do not replace a thorough preflight
briefing on TFR times and locations. Not all TFRs may be shown. To
determine accurate TFR information, verify with official sources, i.e.,
preflight planning or flight service center.
NOTE: All visual depictions contained within this document, including
screen images of the GTN bezel and displays, are subject to change and
may not reflect the most current GTN software. Depictions of equipment
may differ slightly from the actual equipment.
NOTE: This device complies with part 15 of the FCC Rules. Operation is
subject to the following two conditions: (1) this device may not cause
harmful interference, and (2) this device must accept any interference
received, including interference that may cause undesired operation.
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.

GTN 725/750 Cockpit Reference Guide
190-01007-04 Rev. M
NOTE: Do not use SafeTaxi or Chartview functions as the basis for ground
maneuvering. SafeTaxi and Chartview functions have not been qualified
to be used as an airport moving map display (AMMD). SafeTaxi and
Chartview should only be used by the flight crew to orient themselves
on the airport surface.
NOTE: The FAA has asked Garmin to remind pilots who fly with Garmin
database-dependent avionics of the following:
• It is the pilot’s responsibility to remain familiar with all FAA regulatory
and advisory guidance and information related to the use of databases
in the National Airspace System.
• Garmin equipment will only recognize and use databases that are
obtained from Garmin or Jeppesen. Databases obtained from Garmin
or Jeppesen are assured compliance with all data quality requirements
(DQRs) by virtue of a Type 2 Letter of Authorization (LOA) from
the FAA. A copy of the Type 2 LOA is available for each database at
flyGarmin.com.
• Use of a current Garmin or Jeppesen database in your Garmin equipment
is required for compliance with established FAA regulatory guidance, but
does not constitute authorization to fly any and all terminal procedures
that may be presented by the system. It is the pilot’s responsibility to
operate in accordance with established AFM(S) and regulatory guidance
or limitations as applicable to the pilot, the aircraft, and installed
equipment.
NOTE: The pilot/operator must review and be familiar with Garmin’s
database exclusion list as discussed in SAIB CE-14-04 to determine what
data may be incomplete. To see if an exclusion report exists for a specific
database, visit flyGarmin.com.

Vertical Calculator (VCALC)
The VCALC page uses GPS position, GPS computed altitude, and
pilot-selected parameters to calculate and display the time to begin descent and
vertical speed required to reach a desired altitude above a designated waypoint
offset. The image below is a sample profile for an aircraft to be at
1,000 feet above KMCI 10 NM from the airport. Since the vertical speed is set
to 400 feet per minute, the decent needs to begin in 7 minutes and 15 seconds.
At the present location, a vertical speed of -244 feet per minute is required to
reach the target. There are no menu options for the VCALC Profile page.

Connext Setup - Flight Stream 210 and 510
The GTN interfaces with the Flight Stream 210 Bluetooth transceiver and
Flight Stream 510 wireless datacard. Using a Flight Stream and the GTN,
flight plans are sent and received over Bluetooth. In addition, GPS position is
provided from the GTN and attitude is forwarded from a connected GDU. The
GTN can also configure the Flight Stream’s Bluetooth.
The Flight Stream 510 also includes a Wi-Fi transceiver for updating
databases. For more information on updating databases with a
Flight Stream 510, refer to GTN 725/750 Pilot’s Guide, P/N 190-01007-03.
The GTN can configure the Flight Stream 510’s Wi-Fi.

Pairing a Device
New devices can only be paired with the Flight Stream when it is in “Pairing
Mode.” The Flight Stream will be in pairing mode when the GTN is navigated
to the Connext Setup page and/or the Manage Paired Devices page. The pairing
must be initiated by the portable device. Pop-ups requesting confirmation of
the pairing display on both the GTN and the portable device.

Connext Operation with Flight Stream 210 and 510
Data output from the GTN and Flight Stream occurs automatically and
requires no pilot action (such as, flight plan, GPS position, and attitude).
Additionally, ADS-B traffic and weather can be output from the Flight Stream
when connected to a GDL 88 or GTX 345 and XM WX and SiriusXM satellite
radio information can output when connected a GDL 69. The Flight Stream
210 and 510 both support sending and receiving GSR 56 SMS messages and
controlling the GSR 56 Iridium phone when used with a compatible portable
application.
From the Connext Setup page, the pilot can enable or disable Flight Stream
features (flight plan importing, phone/SMS, and database transfers), setup
Flight Stream Bluetooth and Wi-Fi, and manage paired Bluetooth devices.
On the GTN’s Paired Devices page, the device status indicates if the portable
device is connected and communicating with the Flight Stream. The
“Auto-Reconnect” setting determines if the Flight Stream will automatically
connect to up to four devices when in range. When this setting is disabled,
the pilot must initiate the connection from the device. For devices that always
reconnect automatically, this setting will not be shown. Removing a device
from this page by pressing “Remove” will require the device to be paired again
before transferring data.
NOTE: If the pairing is removed from either device (portable device or
GTN) it must be removed on the other device before a new pairing to that
same device is established again. Essentially, pairing must be removed on
both devices before repairing.

Connext Setup for GMA 35c
From the Connext Setup page, the pilot can enable/disable Bluetooth,

page, the device status indicates if the portable device is paired and connected.
To connect a different device when the maximum number are already
connected, the existing connection must be ended by removing the portable
device pairing or by disconnecting or disabling Bluetooth on the portable
device. Removing a device from this page by pressing “Remove” will require
the device to be paired again before reconnecting.
NOTE: Only one portable device can be connected to the GMA 35c at a
time.
New devices can only be paired while the unit is in “Pairing Mode.” Pairing
mode is active while on the Connext Setup page or the Manage Paired Devices

long as the pilot is notified. Certain waypoints in the navigation
database are not referenced to the WGS84 datum, or their reference
datum is unknown. If this is the case, this message is displayed.
Garmin cannot determine exactly how close the non-WGS84
referenced waypoint will be to the WGS84 datum that the GTN uses.
Typically, the distance is within two nautical miles. The majority of
non-WGS84 waypoints are located outside of the United States.

GLOVE QUALIFICATION PROCEDURE
The touchscreen uses capacitive touch technology to sense the proximity of
skin to the display. A glove creates a barrier between the skin and the display
glass, potentially reducing the ability of the display to detect touches.
This procedure qualifies a specific glove for use with the touchscreen. Due
to differences in finger size, glove size, and touchscreen between the GTN 6XX
and GTN 7XX units, the qualification procedure is specific to the pilot/glove
and GTN combination. Multiple units must be evaluated individually.
Glove Selection Considerations
• Thinner gloves perform better than thicker gloves
• Leather gloves, and gloves designed specifically for use with capacitive
touchscreen devices, are often found to be acceptable
• To improve touchscreen sensitivity while wearing gloves, use the pad of
your finger instead of the tip during touch interactions
Glove Qualification Guidance
• The “Tests Required for Glove Qualification” table contains the tasks
required to qualify a glove
• The “Tests Not Required for Glove Qualification” table contains tasks that
are not required to qualify a glove, but may limit how some functions are
accessed while wearing a glove
Glove Qualification Steps
Complete only the tasks for the capabilities relevant to the installed GTN(s).
1. Sit in the pilot’s seat.
2. Start the GTN in demo mode by pressing and holding the Direct To key
during power up.
3. Perform the tasks listed in he following sections, tapping each key with a
non-gloved finger. It is not necessary to record any results for this step.
4. Repeat step 3 using a gloved hand.
5. For each task, determine whether the touchscreen response is the same or
worse than without the glove.

Glove Qualification Procedure
NOTE: This procedure is not authorized for completion during flight.
Perform all tasks while the aircraft is on the ground.
Glove Qualification Procedure
6. Record the results in the applicable table. Items that may cause the operation
to be worse include, but are not limited to:
a. Multiple attempts to select a key
b. Unintentional selection of adjacent key(s)
c. Excessive force on the touchscreen to select a key
7. 7. If all applicable tasks produce the same response with and without a glove,
the pilot may use the glove in flight.

In order to enable voice command functionality crew members must
successfully perform and complete 17/20 (85%) voice commands in the
Telligence aircraft qualification procedure. Crew members must be
comfortable speaking into an aviation headset and proficient in English.
Voice Command Guidelines
NOTE: If a voice command is uninterpretable, verify the system is
performing the intended action or displaying the desired data. If the system
does not recognize a command, use the touchscreen to execute the function.
The GTN Voice Command History details all commands performed.
• Position the headset MIC approximately 1/8 inch from mouth, align with
bottom lip to avoid breath sounds in the microphone.
• Speak conversationally.
• Enunciate.
• Speak in a normal tone and volume.
• Speak at a normal cadence (not too quickly or slowly).
• Pause briefly between activation of the Push to Command (PTC) switch
and when speaking the voice command.
• Review the commands prior to performing the qualification.

QUALIFICATION PROCEDURE
Telligence Voice Command Qualification Procedure
Voice Command Instructions
1. Press and hold the PTC switch.
2. Speak the entire command into the headset MIC.
3. Release the PTC switch.
• A positive tone (low-to-high) indicates the command has been recognized
and executed. (i.e., page changed, radio tuned, MIC selected, etc.)
• A negative tone (high-to-low) indicates the command is either
unrecognizable or invalid.
Successful Command Example
“Show approaches page” is spoken, the approach selection page displays
immediately, and a positive tone sounds.
Unsuccessful Command Example
“Show map page” is spoken and the traffic page displays.
“Show map page” is spoken and a negative tone sounds.
Qualification Procedure
Speak the unbold phrase if the voice command in this procedure is not
applicable to the aircraft’s configuration. If the total number of successful
commands is less than 17, the voice commands must be disabled. For
instructions on how to activate and deactivate voice commands, refer to the
GTN 725/750 Pilot’s Guide, P/N 190-01007-03.
Example: If the requirement states a COM radio is required, but your GTN
does not a have a COM radio, use the unbold command.
1. Start the GTN and acquire a GPS position.
2. Conduct the voice commands in sequential order while wearing an
aviation headset. If necessary, a command can be attempted twice.
3. When the command is successful check the box next to the command.
