SECTION 1 GENERAL DESCRIPTION
1.1 INTRODUCTION
The MD41-151X series products are compact, self-contained Annunciation and Control Units (ACUs). The
fully integrated control unit provides annunciation and mode selection for Global Positioning System
(GPS) / Satellite-Based Augmentation System (SBAS) navigators. This series of the MD41 product family
is specifically designed to work with the Garmin GTN 6XX/7XX
derivatives with equivalent functionality. It combines the necessary functions and annunciations required
to interface with an approved system and provide regulatory compliance with GPS/SBAS minimum
performance specifications.
Highlighted features include long-life LEDs used for all lighting, internally backlit selection switches, deadfront inactive annunciations, and the installation option for manual or automatic dimming. An external
annunciation dimming adjustment is provided for balancing low-level light conditions.
