Portable Battery Eliminator for XPR 3000 & XPR 7000 Series

The Motorola PMNN4428A Portable Battery Eliminator is a professional service accessory designed to provide regulated external power to compatible Motorola MOTOTRBO portable two-way radios during testing, servicing, tuning, and alignment procedures.

Designed for compatible XPR 3000 Series and XPR 7000 Series portable radios, the PMNN4428A takes the place of the radio's rechargeable battery during bench service applications.

The battery eliminator provides a 7.5V regulated power connection, allowing technicians to operate a compatible portable radio from an appropriate external DC power source instead of relying on a rechargeable battery.

This makes the PMNN4428A particularly useful for radio service centers, Motorola dealers, communications technicians, and organizations that perform maintenance and testing on their own MOTOTRBO portable radio fleets.

Motorola service documentation specifically identifies PMNN4428 as the battery eliminator used with the XPR 3300 / XPR 3500 and XPR 7350 / XPR 7380 / XPR 7550 / XPR 7580 radio platforms.

7.5V Universal Battery Eliminator

The PMNN4428A is identified as a:

7.5V Universal Battery Eliminator

During service procedures, the battery eliminator replaces the radio's normal rechargeable battery and allows the radio to receive regulated external power.

This provides technicians with a consistent power source during testing and helps prevent changing battery charge levels from affecting extended service procedures.

Service and Testing Applications

The PMNN4428A is intended primarily for professional radio service applications such as:

• Radio diagnostics

• Radio troubleshooting

• Transmitter testing

• Receiver testing

• Radio tuning

• Radio alignment

• Performance verification

• Service-monitor testing

• Bench servicing

• Repair verification

• Technical maintenance

Motorola service procedures may use the battery eliminator together with additional equipment such as a service monitor, test box, RF adapter, programming cable, and regulated external power supply.

XPR 3000 Series

Motorola service documentation specifies the PMNN4428 for compatible:

XPR 3300 / XPR 3500

portable radios.

The battery eliminator can be used during supported service, testing, tuning, and alignment procedures for these radio platforms.

XPR 7000 Series

Motorola also specifies the PMNN4428 for compatible:

XPR 7350 / XPR 7380 / XPR 7550 / XPR 7580

portable radios.

These radios use the PMNN4428 as part of compatible professional service and alignment configurations.

Battery Eliminator vs. Radio Battery

The PMNN4428A is a:

Service Battery Eliminator

It is not a rechargeable portable-radio battery.

The battery eliminator is intended to take the place of the radio's normal battery while the radio is connected to appropriate external power during service procedures.

It is primarily intended for bench testing and maintenance rather than normal portable operation.

Additional Equipment

Depending on the service procedure being performed, additional equipment may be required, including:

• Regulated DC power supply

• Battery eliminator cable or interface

• Motorola programming cable

• Motorola RLN4460 test box

• RF adapter

• RF test cable

• Service monitor

• Computer with appropriate Motorola service software

These items are not included unless specifically stated.

Important

The PMNN4428A is a professional radio service accessory.

It is not a rechargeable battery.

It is not a battery charger.

It is not intended to replace a portable radio battery for normal field operation.

An appropriate regulated external power source and additional service equipment may be required.

The portable radio, external power supply, programming equipment, and test equipment are sold separately.

Always follow the appropriate Motorola service procedures when connecting and servicing a portable radio.
