The Motorola wireless remote speaker-mic (WRSM) is a popular accessory for APX, XTL, and XPR series hand-held and vehicle mounted two-way radios.

Paired with portable radios it provides range about 30 feet and with the PMMN4097 mobile palm mic/gateway you can roam up to 300 feet from the vehicle. There is “mission critical” for APX and a “operations critical” software version for MOTOTRBO DMR radios.

 Choose the Correct Wireless Mic for your Motorola Radio

Motorola’s model nomenclature and product tiering make it easy to purchase the wrong mic for your radio. Depending on the included charger bundle the product SKU changes slightly. Below is a summary of the configurations and their compatible radios.

Hand-held APX Series With Internal Bluetooth Enabled

• RLN6554 – Wireless RSM with Battery, Clip (RLN6544) and Dual Unit Charger (PMLN7120)
• RLN6544 – Mission Critical Wireless RSM with Battery and Clip Only

These models are compatible with APX 8000, APX 7000, APX 7000XE, APX 6000, APX 6000XE, APX 4000, APX 3000, and SRX 2200.

It is important to make sure your radio has Bluetooth enabled. The blue dot means is has the internal hardware only. You also need to have the software option (free since April 2016) and your programmer has it turned ON. Notice this same mic can also be used with the PMMN4097 mobile palm mic/gateway.

Adding this wireless mic is easy – replace the palm mic with the combo mic/gateway and “touch-pair” – that’s it. APX users can use the same mic with their portable hand-held radio.
