or
Battery pack –40 °C 85-740-004
‘O’ ring 85-725 x 2
Screw M3x20 85-728
The replacement procedure is the same for both types of battery.
NOTE: Later –20 °C battery packs are larger than the original versions; this modification
enables the PLB to float when fitted with the later battery pack.
Method
1. Remove the battery retaining screw and detach the battery. Dispose of this battery in
accordance with local regulations.
2. Inspect the battery pins on the PLB to ensure they are not bent or corroded.
3. Fit the two ‘O’ rings to the battery connectors. It is recommended to fit these to the
pillars, rather than placing them in the recesses of the battery pack, but either method
may be used as desired.
4. Assemble the battery pack to the PLB, taking care that the ‘O’ rings stay in place.
5. Fit the securing tag attached to the lanyard.
It is essential that this part is fitted, as
it forms part of the PLB sealing system.
6. Fit the screw to retain the battery pack. Tighten the screw to a torque of 25 cNm.
