User's Manual

Even if the GPS PLB initially fails to acquire a valid GPS position, the first alert

message will still be transmitted within 2 minutes of activation. The PLBs position will

be determined as if it was a standard PLB without GPS.

Using the PLB afloat

The PLB is totally waterproof but is not designed to operate when floating on the

surface of the water. It is buoyant and will not sink if dropped into water, if possible

keep it out of the water when in use, place it high up on your PFD, lifejacket. or chest

and clear of any wave wash. Any trapped water should be removed periodically by

shaking the PLB.

Aboard a liferaft

The principle is to give the PLB as clear a view of the sky as possible whilst keeping it

flat. If the raft is full, it may be necessary to elevate the PLB or hold it outside the

liferaft canopy. Attach the lanyard to your clothing so in the event of separation from

the life raft the PLB will stay with you.

Aboard ship

Operate the PLB on deck; position it to have the clearest possible view of the sky. Lay

it flat on the deck with the antenna pointing up towards the sky .

Aviation

The PLB is not designed for activation aboard an aircraft although they are often used

as an additional carry off safety device. Take care not to place the PLB in the shadow

of the aircraft. Lay it on a flat surface with the antenna pointing up towards the sky

and with the maximum amount of sky possible in view.

Vehicles

Because of the shielding effect, the PLB probably will not operate effectively when

inside a vehicle. It is best placed outside on the roof, hood or trunk.
