3 DESCRIPTION
The EPIRB is a powerful self-contained distress transmitter. It is powered by a Lithium
battery that has a replacement interval of 5 years. An EPIRB is intended to be a one-
shot device; once activated it will operate for at least 48 hours. It operates best while
floating in water, but it can also be operated while on board a vessel or in a life raft.
The key components of your EPIRB are:
Antenna This is a flexible whip. It must be near vertical when operating.
If the antenna gets bent, gently straighten it out.
Strobe light These are the bright white LEDs visible through the clear lens
dome. When the EPIRB is activated they will flash every few
seconds.
Red LED Visible through the clear lens dome at the rear of the EPIRB.
This stays on or flashes to show which mode the EPIRB is in.
Green LED Where fitted (beside the red LED), this flashes when the GPS
acquires a position fix.
Sea switch The two studs on the sides of the EPIRB are sea switch contacts.
Submerge these in water to activate the EPIRB automatically.
Keep these contacts clean – see section 10.2
Activation switch Pull the tear-off tab upwards to release the switch, then push the
switch in and move it fully left.
Test button This button enables the user to run test sequences to verify the
readiness of the EPIRB.
Lanyard Pull the lanyard spool down to free it. Use the cord to tether the
EPIRB to a survival craft.
