3. OPERATING INSTRUCTIONS
The Tron 40GPS is designed to be operated either manually or automatically.The
EPIRB is always armed, that is the EPIRB will automatically start to transmit when
the EPIRB is out of the bracket and deployed into water. In the lower part of the
EPIRB there is an automatic safety switch.This switch prevents the seawater-
contacts from operating the EPIRB (caused by ice, sea-spray etc.) as long as the
EPIRB is placed in its bracket.
