406 mhz Technology • 406 ELT MAS 2009 Presentation
Direction Finder (“Rhotheta”) • Supports new 406MHz as well as 121.5MHz
Turning the unit on 4 – antenna version/serial number 5 – display version/serial number
General Functions 8 – to dim, press and release REP and turn PAGE knob 9 – to change pages, rotate page knob
Direction Finder Mode 1 – frequency selection 4 – clear averaging value (3 seconds) 6 – repeat last good signal
Setting the Squelch Correctly set squelch for NO SIGNAL being received Incorrectly set squelch (listening to noise)
Setting the Squelch Automatic squelch set by system, can be manually overridden, to go back to automatic set squelch to 0% or above 60%
Setting the Squelch Squelch controlled by the system (cannot be overridden)
