5-30 Disassembly/Reassembly Procedures Ensuring Radio Immersibility
5.8 Ensuring Radio Immersibility
This section discusses radio immersibility concerns, tests, and disassembly and reassembly of the
XPR series radios.
5.8.1 Servicing
The XPR series radios shipped from the Motorola factory have passed vacuum testing and should
be capable of restoring the watertight integrity of the radio.
5.8.2 Accidental Immersion
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.
5.8.3 Specialized Test Equipment
This section summarizes the specialized test equipment necessary for testing the integrity of the
XPR series 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/
instrument (Table 2-2 on page 2-2) is authorized by Motorola and needed to perform the vacuum
check and pressure testing, if required. Any equipment/tools/instruments not mentioned in the table
must not be used to perform these test.
5.8.4 Vacuum Pump Kit NLN9839
The vacuum pump kit includes a vacuum pump with gauge, and a vacuum hose. A connector fitting
(part number 5871134M01) and fitting seal (part number 3271133M01) pump connector, which must
be ordered separately, connects the vacuum hose to the radio’s chassis.

It is strongly recommended that the 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 immersibility be checked annually by
qualified service personnel/workshop that is authorized by Motorola.
