Long-term storage of a transmitter is best accomplished by following the following steps:
1. Remove the cap from the transmitter and remove all batteries from the battery carousel
2. Ensure that the O-Ring and the O-Ring‟s mating surface have a thin film of a petroleum jelly
such as Vaseline. This will help prevent the O-Ring from being deteriorated by the
environment.
3. Do not reassemble the cap onto the transmitter for long-term storage with the O-Ring in place;
this could cause the O-Ring seal to take a shape flattened on the outside where it meets the
mating surface of the transmitter. Such a flattened face could degrade the O-Ring‟s ability to
hold pipeline pressure. If you need to store the transmitter in an assembled state, we
recommend removal of the O-Ring
4. When reassembling the transmitter after a period of long-term storage, please follow the
routine assembly inspection steps.
