If the battery of the BioPak 240R monitor fails, how can I determine how much oxygen remains?
In the case of battery failure causing the TRIM indicator to shut down, the user can determine remaining oxygen simply by viewing the pressure gauge mounted to the shoulder harness of the BioPak. In all cases of battery failure the user is instructed to immediately return to a safe location and doff the BioPak. These instructions are presented to the user in the User Manuals as well as during User Training sessions.
