4.4.2 Battery Changing Procedures
Note. Before changing batteries in a dirty environment it is recommended that, in order to minimize
contamination, the new O-ring is fitted to the new lid assembly (or cleaned lid assembly from a previous
installation) in a clean area, and the lid sealed in a polythene bag.
