PLEASE READ - IMPORTANT! PLEASE READ - IMPORTANT! PLEASE READ - IMPORTANT!
WHEN USING IN AN EMERGENCY, REMOVE THE ELT FROM ITS MOUNT, EXIT AIRCRAFT, AND SET
TOGGLE SWITCH TO THE “ON” POSITION. THE ELT’S LED SHOULD BE BLINKING.
TESTING SHOULD NOT BE DONE WITH NIGHT-VISION GOGGLES. DO TEST BEFORE START-UP!
A “3 CODE” IS COMMON WHEN TESTING WITH THE TAPE ANTENNA. THIS CAN LEAD TO AN
AMBIGUOUS INTERPRETATION OF HOMER POWER. SECTION 6 DESCRIBES TEST PROCEDURES TO
ELIMINATE THIS AMBIGUITY.
CERTAIN INSTALLATIONS WILL GENERATE A “4 CODE” (BAD 406 MHZ VSWR). VERIFY THAT THE
ANTENNA IS WORKING BY REMOVING ELT FROM ITS MOUNT, AND RE-DOING THE SELF-TEST.
DURING NORMAL USE, KEEP THE 15-PIN D-SUB CONNECTOR DRY, AND FREE OF CONTAMINATION.
WHEN INSTALLING THE BB-12M, USE THREE MOUNTING SCREWS. USE HOLE PATTERN A OR B. REFER
TO PAGE 7. THE BB-15M REQUIRES FOUR MOUNTING SCREWS.
