Ensuring Radio Submergibility

This section discusses radio submergibility concerns, tests, and disassembly and reassembly of
ASTRO APX 3000 radios.
8.7.1 Standards
ASTRO APX 3000 radio models meet the stringent requirements of IP67, which require the radio to
maintain watertight integrity when immersed in one (1) metre water for 30 minutes.
8.7.2 Servicing
APX 3000 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.
8.7.3 Specialized Test Equipment
This section summarizes the specialized test equipment necessary for testing the integrity of ASTRO
APX 3000 radios.
To ensure that the radio is truly a watertight unit, special testing, test procedures, and specialized
test equipment are required. The special testing involves a vacuum check of the radio and pressure
testing (troubleshooting) for water leaks if the vacuum check fails. The specialized test equipment is
needed to perform the vacuum check and pressure testing, if required.
8.7.3.1 Vacuum Pump Kit NLN9839_
The Vacuum Pump Kit includes a Vacuum Pump with gauge and a Vacuum Hose. The Vacuum Test
Fixture (P/N 66012075001) which connects the vacuum pump to the radio, must be ordered
separately.
8.7.4 Disassembly
Disassemble the radio according to
Disassembly/Reassembly Procedures: Ensuring Radio Submergibility
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.
