If the Nonin Personal Care Product device won't turn on, it might be due to depleted batteries. Try replacing all four batteries. Alternatively, the batteries may be installed incorrectly; check their orientation. If the issue persists, there might be a missing or damaged metal contact in the battery compartment, in which case you should contact Nonin Technical Service.
