8.10 Ensuring Radio Submergibility

This section discusses radio submergibility concerns, tests, and disassembly and reassembly of
ASTRO XTS 5000 R radios.
8.10.1 Standards
ASTRO XTS 5000 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 three feet of water for two hours.
8.10.2 Servicing
XTS 5000 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.
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
C a u t i o n
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.
8.10.3 Accidental Submersion
If the radio is accidentally dropped in water, shake the radio to remove the excess water from the
speaker grille and microphone port area before operating; otherwise, the sound may be distorted
until the water has evaporated, or is dislodged from these areas.
8.10.4 Specialized Test Equipment
This section summarizes the specialized test equipment necessary for testing the integrity of ASTRO
XTS 5000 R 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.
8.10.4.1 Vacuum Pump Kit NLN9839
The vacuum pump kit includes a vacuum pump with gauge, and a vacuum hose. An adapter with
gasket (NTN9279A), which must be ordered separately, connects the vacuum hose to the radio's
casting. The vacuum pump kit is also used on Motorola ASTRO SABER R radio models. The
adapter with gasket is the same as that for the ASTRO XTS 3000 R and XTS 3500 R radio models.
8.10.4.2 Pressure Pump Kit NTN4265
The pressure pump kit includes a pressure pump with gauge, and a pressure hose; the pressure
pump kit is also used on Motorola ASTRO SABER R radio models. As with the vacuum pump kit
above, the NTN9279A adapter connects the pressure hose to the radio's casting.
