BENDIX/KING KN 62/62A/64 SECTION I GENERAL INFORMATION INTRODUCTION This manual contains information relative to the physical, mechanical, and electrical characteris- tics and installation procedures for the KN 62/62A/64 DME. The KN 64 has lower output power than the KN 62/62A. The KN 64 is not TSO’ed. EQUIPMENT DESCRIPTION The KN 62/62A/64 is a panel mounted, 200 channel DME employing the latest state of the art sol- id-state transmitter and large scale integrated circuit (LSI) technology.

BENDIX/KING KN 62/62A/64 SECTION II INSTALLATION GENERAL INFORMATION This section contains information relative to the installation and wiring of the KN 62/62A/64 DME. A close adherence to methods and procedures discussed herein is required. 2.1.1 KN 62A ONLY The conditions and tests required for TSO approval of this article are minimum performance stan- dards.
Recommendations on stack cooling are contained in Bendix/King Installation Bulletin #55 and #143 revised. Failure to provide stack cooling will certainly lead to increased avionics maintenance costs and may void the Honeywell warranty. 2.3.2 KN 62/62A/64 INSTALLATION (FIGURES THROUGH 2-18) Plan a location on the aircraft panel that is clearly visible and within easy access of the pilot.

Solderless Contact Terminal Assembly using Pliers Strip each wire 5/32” for contact terminal (P/N 030-01107-0030). (The last two digits of the contact terminal part number indicate the number of terminals furnished).
BENDIX/KING KN 62/62A/64 antenna and six (6) feet from a transponder antenna. Where practical, plan the antenna location to keep cable lengths as short as possible, and avoid sharp bends in the cable to minimize the VSWR. To prevent RF interference, the antenna must be physically mounted a minimum distance of three feet from the KN 62/62A/64.
BENDIX/KING KN 62/62A/64 SECTION III OPERATION GENERAL It is recommended that power to the KN 62/62A/64 be turned on only after engine start-up, as this procedure increases the reliability of the solid state circuitry. The KN 62/62A/64 front panel controls consist of an ON-OFF switch, a function switch, and fre- quency selection knobs (Figure 3-1).
BENDIX/KING KN 62/62A/64 When operating dual KN 62/62A/64’s, the respective DME’s will interfere with each other when the NAV frequencies differ by 5.3MHz (for example, 108.00MHz and 113.3MHz). This interfer- ence results in premature flags or loss of ”Lock-On”. Should this occur, one of the KN 62/62A/64’s should be either turned off or tuned to a different NAV frequency so that the 5.3MHz difference is eliminated.
