Those P7300 radios labeled “immersible” (see Figure 11-1) require periodic testing using specialized
equipment to verify the radio’s watertight integrity.
Preventive Maintenance for Immersion-Rated Radios
P7300 multi-mode series portable radios with Immersion Option MAEV-PKGMR
must be serviced by a service center authorized and certified by Harris to perform the
necessary tests to verify watertight integrity. As part of a thorough preventive
maintenance plan, Harris recommends Immersion-Rated P7300 multi-
portable radios be, at a minimum, tested and re-certified on an annual basis. Harris
further recommends that the radios be tested on or close to the anniversary of the
ship date printed on the Model Number label on the back of the radio (see Figure
11-1).
