TESTING THE ALERT2 TRANSMITTER

1. Arm the ALERT2 Transmitter by turning 

the cap clockwise until the cap is closed 
tight. Failure to close completely may allow
water to enter electronics compartment 
which will damage the unit.

2. Dip the ALERT2 Transmitter in a bucket of

water, or wet fingers and touch both metal 
probes on transmitter. One of the metal 
probes is located inside the black rubber 
boot.

audible sound once transmission has begun.

The ALERT2 Man-Overboard Alarm System

 

consists of an ALERT2 Man-Overboard Receiver

 

and one or more ALERT2 Man-Overboard 
Transmitters

. In addition, an optional ALERT2 

Man-Overboard Portable Direction Finder

 can be 

utilized to home in on an ALERT2 transmission 
signal from up to 1 nautical mile.

completely. (In the event of changing 
batteries).

Upon activation of the Transmitter by either totally 
immersing the transmitter in water (salt or fresh), or 
by manual activation, a coded radio signal will be 
transmitted to the ALERT2 Receiver, causing its 
alarm to sound.
