CURRENT REVISION DESCRIPTION

SectionNumber

Description of Change

1.3.4.1 Updated modulation and frequency range of the COM transmitter.

1.3.4.2 Updated frequency range of the COM receiver.

1.5.1 Updated Table 1-4 with ETSO information.

1.5.3 Added deviations for ETSO-2C40c, ETSO-C118, ETSO-C146, and ETSO-C147.

2.1Added, To mitigate against the loss of navigation and communication, installation ofsecond navigation and/or communication system may be required.

2.2Added, To meet requirements for Part 25, 27, and 29 aircraft, it is necessary to install asecond VHF communications radio.

4.4 Deleted, Connector, BNC, Male, Clamp from section.

4.9 Changed 010-2042-000 to 030-2042-000 in Table 4-5.

5.1.2 Corrected figure of P1002 connector.



6.6.6.1 Changed range of photocell transition from 0 to 5.

6.9.5.4

Added, The default value of 24 seconds is a nominal value for most aircraft. This valuecan be changed depending on the types of operations the aircraft is expected to

encounter to Auto Standby Delay information.Added, This field should be set to the typical vertical speed climb rate of the aircraft.This number determines the rate of climb necessary for the GTN to assume lift-off fordetecting an airborne state. Refer to the Pilots Operating Handbook (POH) to determinethis value. If the POH does not include aircraft climb rate information, use the defaultvalue of 300 fpm To Altitude Climb Rate for Airborne Transition information.

Appendix C Updated Backplate Kit Content Differences in Figure C-2.

Appendix D

Figure D-2, D-3 and D-4: Added fan.Figure D-5: Simplified entire figure.Figure D-9: Changed interconnect to illustrate wiring for single/dual GTNs to single/dual

transponders, with and without TIS.Figure D-24: DeletedFigure D-25: Added SUSPEND ANNUNCIATE discrete and note 6.

WARNING

This product contains a lithium battery that must be recycled or disposed of properly.Battery replacement and removal must be performed by professional services.

CAUTION

To avoid damage to the GTN, take precautions to prevent Electro-Static Discharge (ESD)when handling the GTN, connectors, fan, and associated wiring. ESD damage can beprevented by touching an object that is of the same electrical potential as the GTN beforehandling the GTN itself.

CAUTION

The GTN 625, GTN 635 and GTN 650 has a display that is coated with a special anti-reflective coating and is very sensitive to waxes and abrasive cleaners. CLEANERSCONTAINING AMMONIA WILL HARM THE ANTI-REFLECTIVE COATING. It isvery important to clean the display using a microfiber cloth or with a clean, lint-free clothand an eyeglass lens cleaner that is safe for anti-reflective coatings.

1. GENERAL DESCRIPTION

1.1 Introduction

This manual is applicable for units with main software version 2.00 or later. This manual describes thephysical, mechanical, and electrical characteristics, as well as instructions and other conditions andlimitations for installation and approval of the GTN units. Refer to Section2,Limitations, for additional

information and other considerations.NOTE

Except where specifically noted, references made to GTN will equally apply to theGTN 625, GTN 635, and GTN 650. All screen shots used in this document are current atthe time of publication. Screen shots are intended to provide visual reference only. Allinformation depicted in screen shots, including software file names, versions, and partnumbers, is subject to change and may not be up to date.

1.2 Equipment Description

The GTN 625 is a GPS/SBAS unit and may be approved for IFR en route, terminal, non-precision, andprecision approach operations. The GTN 625 meets the requirements of the TSO specified inTable 1-4.

The GTN 635 includes all of the features of the GTN 625 in addition to an airborne VHF communicationstransceiver. The GTN 635 meets the requirements of the TSO specified inTable 1-4.

The GTN 650 includes all of the features of the GTN 625 in addition to an airborne VHF communications

transceiver and airborne VOR/localizer (LOC) and glideslope (G/S) receivers. The GTN 650 meets therequirements of the TSO specified inTable 1-4.

CAUTION

The GTN has a display that is coated with a special anti-reflective coating that is verysensitive to waxes and abrasive cleaners. CLEANERS CONTAINING AMMONIAWILL HARM THE ANTI-REFLECTIVE COATING. It is very important to clean thedisplay using a clean, lint-free cloth and an eyeglass lens cleaner that is specified as safefor anti-reflective coatings.

CAUTION

The use of ground-based cellular telephones while aircraft are airborne is prohibited by

FCC rules. Due to potential interference with onboard systems, the use of ground-basedcell phones while the aircraft is on the ground is subject to FAA regulation 14CFR 91.21. FCC regulation 47 CFR 22.925 prohibits airborne operation of ground-based cellular telephones installed in or carried aboard aircraft. Ground-based cellulartelephones must not be operated while aircraft are off the ground. When any aircraftleaves the ground, all ground-based cellular telephones on board that aircraft must beturned off. Ground-based cell phones that are on, even in a monitoring state, can disruptGPS/SBAS performance.

1.4 License Requirements

The Telecommunications Act of 1996, effective February 8, 1996, provides the FCC discretion toeliminate radio station license requirements for aircraft and ships. The GTN 6XX installations mustcomply with current transmitter licensing requirements. In the US, to find out the specific details onwhether a particular installation is exempt from licensing, please visit the FCC web sitehttp://wireless.fcc.gov/aviation. If an aircraft license is required, make application for a license on FCCform 404, Application for Aircraft Radio Station License. The FCC also has a fax-on-demand service toprovide forms by fax. Outside the US, contact the responsible telecommunication authority. TheGTN 625, 635, and 650 owner accepts all responsibility for obtaining the proper licensing before usingthe transceiver. The maximum transmitting power, modulation identification, and frequency bandinformation may be required for licensing and are detailed in Section 1.4.4.

CAUTION

The VHF transmitter in this equipment is guaranteed to meet Federal CommunicationsCommission acceptance over the operating temperature range. Modifications notexpressly approved by Garmin could invalidate the license and make it unlawful tooperate the equipment.

1.5 Regulatory Compliance

1.5.1 TSO Authorization and Advisory Circular References

The conditions and tests required for TSO approval of this article are minimum performance standards. Itis the responsibility of those installing this article either on or within a specific type or class of aircraft todetermine that the aircraft installation conditions are within the TSO standards. TSO articles must have

separate approval for installation in an aircraft. The article may be installed only in compliance with 14CFR part 43 or the applicable airworthiness requirements.

All GTN unit functions are design approved under the TSO. Unauthorized changes or modifications toany GTN unit product may void the compliance to required regulations and authorization for continuedequipment usage.
