Disassembly/Reassembly Procedures

Ensuring Radio
Submergibility
Introduction 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. XTS 5000R 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 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.
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.
General Information 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.
Specialized Test
Equipment
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 radios.
The adapter with gasket is the same as that for the ASTRO XTS 3000R
and XTS 3500 R.
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 radios. As with the vacuum pump kit above, the NTN9279A
adapter connects the pressure hose to the radio’s casting.
