WARNING

CAUTION

WARNINGS/CAUTIONS/NOTES

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.

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.

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/.

WARNINGS \ CAUTIONS \ NOTES

To reduce the risk of unsafe operation, carefully review and understand all aspects of the GTX 3X5 Pilot’s Guide. Thoroughly practice basic operation prior to actual use.

The display surface is coated with a special anti-reflective coating that is very sensitive to skin oils, waxes, and abrasive cleaners. It is very important to clean the lens using an eyeglass lens cleaner that is specified as safe for anti-reflective coatings with a clean, lint-free cloth.

Traffic information is provided as an aid in visually acquiring traffic. Pilots must maneuver the aircraft based only upon ATC guidance or positive visual acquisition of traffic.

Unauthorized repairs or modifications could result in permanent damage to the equipment, and void your warranty and your authority to operate this device under FCC and FAA regulations.

WARNINGS/CAUTIONS/NOTES

NOTE

The coverage expected for all operations (transponder replies to ATC, ADS-B and FIS-B reception) from the Garmin GTX 3X5 is limited to line of sight. Low altitude or aircraft antenna shielding by the aircraft itself may result in reduced range. Range can be improved by climbing to a higher altitude.

This product does not contain any user-serviceable parts. Repairs should only be made by an authorized Garmin service center.

WARNINGS \ CAUTIONS \ NOTES

It is the responsibility of the GTX 3X5 owner, residing outside of the U.S., to obtain proper licensing before using the transponder.

Automatic Dependent Surveillance–Broadcast (ADS-B) is an important part of the FAA's NextGEN effort. ADS-B is a precise GPS-based surveillance system that provides ATC access to traffic data well beyond the capabilities of RADAR alone. It enables the display of precise traffic data in cockpits equipped to receive ADS-B.

For more information about ADS-B, visit the Garmin ADS-B Academy website. www.garmin.com/us/intheair/ads-b/

2 GTX 3X5 CONTROLS

2.1 Panel Mount Transponder Controls

The GTX 3X5 series transponders have an auto-dimming display and keypad layout. The keys access the transponder’s controls and features.

Powers on, disables altitude reporting.

ALT

Powers on, enables altitude reporting.

VFR

Changes to the preprogrammed squawk code for VFR.

OFF

Powers off.

SBY

Powers on or changes into standby mode.

IDNT

Activates the Ident function.

2.2 Mode Selection Keys

2 - GTX 3X5 CONTROLS

The transponder system no longer supports a pilot selectable GND mode. The transponder should always be in ALT mode prior to moving on the airport surface. It must be in ALT mode when operating in certain controlled airspace, in accordance with 14 CFR 91.215. For guidance on transponder operation, refer to the FAA Aeronautical Information Manual (AIM), 4-1-20(a)(3).

When on the ground or in the air always operate the transponder in ALT mode, unless otherwise requested by ATC. It is acceptable to go directly from OFF to ALT mode. It is not necessary to place in SBY mode for a “warm up” period. The transponder automatically determines whether the aircraft is in the air or on the ground and sends that information to other aircraft and ATC.

Automatic ALT Mode Switching

If the unit is configured for Automated Airborne Determination and senses a transition from on ground to in air, the unit automatically switches from SBY to ALT mode.
