Functions
Activation
The SLB 406 can be activated in two modes: 1) Automatic Activation, and 2) Manual
Activation. The Automatic Activation mode requires the use of the automatic activation
lanyard/Activation Lanyard attached to a life raft or the inflatable portion of a life vest.
In this mode the beacon will be automatically activated upon life vest/raft inflation
without any user action. Beacon activation occurs when the activation lanyard is
separated from the beacon. When the beacon is activated, the red XMIT LED will
illuminate for approximately one second to acknowledge. To activate the SLB 406 in the
Manual Activation mode, press the ACTIVATE button for approximately two seconds
until the red XMIT light illuminates. When the beacon is activated, the red XMIT LED will
illuminate for approximately one second to acknowledge. Figure 5 shows the protective
faceplate of the SLB 406 which protects the buttons from inadvertent activation or
turnoff.
