8.10 Ensuring Radio Submergibility

This section discusses radio submergibility concerns, tests, and disassembly and reassembly of
ASTRO APX 5000 R/ APX 6000 R radios.
8.10.1 Standards
ASTRO APX 5000 R/ APX 6000 R radio models meet the stringent requirements of U.S. MIL-STD-
810C, Method 512.1, Procedure I; MIL-STD-810D, Method 512.2, Procedure I; MIL-STD-810E,
Method 512.3, Procedure I; and MIL-STD-810F, Method 512.4, Procedure I, which require the radio
to maintain watertight integrity when immersed in six (6) feet of water for two hours.
8.10.2 Servicing
APX 5000 R/ APX 6000 R radios shipped from the Motorola factory have passed vacuum testing
and should not be disassembled. If disassembly is necessary, refer to qualified service personnel
and service shops capable of restoring the watertight integrity of the radio.
8.10.3 Water Exposure
If the radio is exposed to water, shake the radio to remove the excess water from the speaker grille
and microphone ports areas before operating; otherwise, the sound may be distorted until the water
has evaporated, or is dislodged from these areas.

or any other accessory that was previously connected or attached to the radio prior
to servicing.
It is strongly recommended that maintenance of the radio be deferred to
qualified service personnel and service shops. This is of paramount
importance as irreparable damage to the radio can result from service by
unauthorized persons. If disassembly is necessary, unauthorized attempts to
repair the radio may void any existing warranties or extended performance
agreements with Motorola. It is also recommended that submergibility be
checked annually by qualified service personnel.
