Diagnostic Function
RLS Siren Models 3997 & 3999 features a "walk-around" diagnostic test function. The user may invoke this
function by holding the "Air Horn" switch while turning on the vehicle's ignition switch. When the "Air Horn"
switch is released the siren will begin a timing sequence which will turn on each control output for about two
seconds. Each output, including the Arrow Stik (in Flash mode) and the siren tones will be cycled during this
sequence. The siren tones will not be heard if the Park-Kill feature is being used and the vehicle is in Park.
This timed feature enables the user to start the diagnostic function, exit the vehicle and observe a brief test can
be interrupted by cycling the vehicle's ignition switch off. After the test, the vehicle's ignition power must be
cycled off and back on to insure that everything is restored to the normal standby mode.
