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 Personal Flotation 
Device (PFD), lifejacket, or chest and clear of any wave wash. Any trapped water in 
the Antenna Well 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 liferaft 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.
