The Motorola XPR7550 IS (Intrinsically Safe) remains one of the most rugged and high-performance commercial DMR portables ever designed for hazardous environments. Built for professionals and hams who need uncompromising durability, loud audio, and long-term reliability, it continues to stand out even in 2025. While discontinued and succeeded by the XPR7550e IS, this single-band handheld is still a benchmark for industrial-grade safety and RF performance.

3 2025 Update & Firmware Notes
Status: The Motorola XPR7550 IS has been discontinued, replaced by the XPR7550e IS featuring Bluetooth and Wi-Fi. The original remains fully supported in MOTOTRBO CPS 2.0 (v2.130 and later) with firmware up to R02.10.01.0001.
Compatibility: Shares programming and accessories with the XPR 7000 series. Batteries and IMPRES chargers remain cross-compatible.
Used-Market Tip: Always verify that the radio includes a genuine IS battery and charger — non-certified replacements void the safety rating.
4 Who It’s For
- Operators needing an Intrinsically Safe DMR radio for hazardous environments.
- Hams seeking maximum ruggedness and audio clarity.
- Collectors of professional-grade Motorola gear.
- Field users working around fuels, dust, or chemicals.
5 Introduction
Released for the Canadian market, the Motorola XPR7550 IS is a specialized variant of the popular XPR 7550. It adds CSA and UL Intrinsically Safe certification to prevent ignition in flammable atmospheres. Its distinctive blue housing not only sets it apart visually but signals its IS status for industrial operators.
6 Design & Build Quality
The XPR7550 IS is built like a tank. The reinforced polycarbonate shell, sealed connectors, and waterproof gaskets make it a trusted companion for mission-critical use. The extra shielding and safety layers make it about 9 mm taller and 127 g heavier than the standard XPR 7550.
7 Controls & Ergonomics
All buttons on the Motorola XPR7550 IS are slightly larger and easier to use with gloves. Dual side buttons are height-offset for tactile feedback, and the power/volume knob turns more firmly to prevent accidental activation.
8 Antenna & Connectivity
The radio uses a standard SMA-male antenna connector – a welcome departure from Motorola’s proprietary fitments. This lets hams attach aftermarket antennas or feedline adapters directly. Integrated GPS adds location tracking for compatible DMR systems.
9 Programming & Software
Programming the Motorola XPR7550 IS is handled through Motorola’s MOTOTRBO CPS 2.0 software, using a standard USB programming cable. Unlike the Bluetooth-enabled XPR7550e or SL7550 models, the XPR7550 IS supports wired programming only, due to its Intrinsically Safe design.
The codeplug structure mirrors the rest of the MOTOTRBO XPR series, so users familiar with radios like the XPR7550 or XPR7580 will feel right at home. Configuration options are deep, covering zones, channels, contacts, signaling, and GPS features, making CPS 2.0 a highly capable tool for advanced operators.
Note (2025): CPS 2.0 now requires a paid subscription tied to a Motorola Business Online account. The older CPS v16.x series still functions for legacy users but is no longer officially distributed.
While the CPS 2.0 software provides an intuitive interface and extensive configuration control, it’s expensive for individual hams – typically around $300 USD for a three-year subscription. That’s a steep entry point compared with the free programming tools offered by brands like TYT, Anytone, or Hytera.
Because of this, many operators prefer to buy used XPR7550 IS units that already include a working codeplug or rely on a local club member who can assist with programming.
10 Performance (Audio, RF & Durability)
Audio: Among the best in class – the Motorola XPR7550 IS delivers clear, powerful sound that cuts through industrial noise.
RF Output: 4 W (UHF) and 5 W (VHF) make it a top performer for an IS-rated radio.
Durability: IP67 and MIL-STD-810 certified — it can withstand dust, water, and drops that would damage lesser handhelds.
11 Battery, Accessories & Package Contents
The IS-certified 7.5 V / 2,150 mAh battery typically delivers 10–12 hours of operation. Charging is handled through Motorola’s IMPRES system (WPLN4219), which is required to maintain full Intrinsically Safe certification. However, it can also be charged using a standard IMPRES desktop charger if IS certification is not a concern – for example, during typical ham radio use.
Original kit included:
- Motorola XPR7550 IS radio (VHF or UHF)
- IS Li-ion battery (PMNN4069AR)
- IMPRES charger & power supply
- Belt clip & dust cover
- User manual & safety documentation
12 Alternatives to Consider
- Motorola XPR7550e IS: Successor with Bluetooth and enhanced receiver sensitivity.
- Hytera PD782i UL913: IS DMR radio with dual PTT and analog support.
- Anytone D878UV II Plus: Dual-band DMR for hams not needing IS certification.
13 Final Verdict
The Motorola XPR7550 IS stands as a legend among Intrinsically Safe DMR handhelds. Its superb audio, solid RF output, and rock-solid construction make it a trusted choice for critical operations and a collector’s favourite in 2025. Despite its weight and costly CPS software, it remains a benchmark of Motorola engineering and rugged professional design.
