Activating the Sea Marshall AU9, AU9-X,
AU9-WF and AU9-HT
Activation commences transmissions on the 121.5MHz search and
rescue (SAR) frequency. Sea Marshall AU9 transmissions continue
after activation until the device is disarmed/switched [OFF] . When the
unit is armed there are two methods of activation.
Audio SOS BEEP s can be heard approximately every 30 seconds and
flashing RED LED s are visible when the unit is transmitting on full power.
This pattern cycles continuously until the unit is disarmed/switched [OFF] .
IMPORTANT NOTE: The unit has two AUTO ACTIVATION
WATER SENSORS (a metal screw on top of the unit and within
the base cap). Both these sensors have to be continuously
immersed for a period of not less than 2 seconds to allow the
unit to wake up and autoactivate, this prevents inadvertent
activation by spray, rain or splashes.
Press the round rubber ACTIVATION BUTTON .
The Sea Marshall AU9 also activates automatically after 2 seconds of
continuous immersion in water.
