transmitter active for 48 hours when activated, and for test sequences. The
battery pack is integrated within the product.
Two water detectors are mounted in the battery pack. These two metal
contacts are located one on each side of the lower housing.

6.5.1
FB-60 float free bracket
The FB-60 float free bracket is a covered bracket with a hydrostatic release
unit (HRU). The HRU releases the Tron 60S/GPS if the bracket is submerged
to a depth of 2-4 meters when a ship is sinking. When the Tron 60S/GPS is
mounted in the FB-60, it operates as an automatic float free unit.
