New Motorola CP100d Entry Level Digital Radio Will Replace the EVX-261 After October
Motorola Solutions announced the cancellation of the Vertex EVX-261 DMR digital radio and no orders will not be accepted after 10/31/2020. The result will be EVX-261 users will not be able to add a digital radio with compatible batteries, chargers, audio accessories, antennas, or belt clips. It may be a good time to refresh your radio communications and take advantage of the technology improvements.
The recommended replacement is a new MOTOTRBO offering in the commercial products product tier. The new CP100d uses the same batteries and charger as the CP185 analog-only radio. CP185 users now have an easy path to upgrade to digital communications.
The CP100d uses the popular 2-pin audio connector that is used with the CP200d, CP185, and BPR40. The radio will have improved battery life and there is an option to add a display.
The non-display radio has 16 channel capability and the display can handle a maximum of 160 frequencies. For more info download the CP100d Data Sheet.

JPS RSP-Z2 Gateway Provides Simple Patch for Radio System Interoperability
The RSP-Z2 dual-channel gateway from JPS Interoperability Solutions located in
Raleigh, NC allows a pair of 2-way radios, IP connections, or a radio and IP connection to be patched together. There are no recurring costs and the RSP-Z2 supports 2/4-wire interfaces, SIP, RTP, and RoIP protocols. JPS offers factory-built cables with connectors for almost every analog and digital radio model ever manufactured.
Easy Solution to Connect Your Existing Radios with WAVE TLK 100 LTE Devices
Users with a large number of existing on-site radios can easily interface with Motorola WAVE OnCloud TLK 100 LTE devices that provide nationwide coverage. All you need is the RSP-Z2 and interface cables for the TLK 100 and your on-site radio.
The TLK 100 and your radio would be dedicated and can not be used for dispatch. Interoperability is automatic on the channels selected on each dedicated radio. Coverage for the on-site donor radio would be limited by the antenna system or repeater.

How to Change Language on Motorola Wireless Remote Speaker-Microphones
We frequently receive support requests from Motorola wireless speaker-mic users to change the language from French back to English. This is caused by accidently turning on the WRSM and holding the PTT button at the same time.
The mics affected are the RLN6554 and RLN6544 for APX series radios, RLN6562 for MOTOTRBO XPR/SL series DMR radios, and the RLN6551 long range wireless mic for vehicle applications.

New Motorola RM250 Wired Speaker-Mic for TLK 100, SL300, SL3500e, SL 7550e Now Available
SL300, SL3500e, and SL7550e MOTOTRBO radios need a battery-powered remote speaker-microphone not available from Motorola Solutions until now. The new IP67 RM250 is Motorola’s first rechargeable wired RSM. It has a Kevlar reinforced coiled cord, ultra-thin head with swivel clip, 3.5mm audio jack, and Micro USB charging port. Battery life is up to 22 hours after a 2 hour charge. The PMLN7560 earpiece with acoustic tube can be used for discreet communications and surveillance.
The RM250 is now compatible with the WAVE PTT TLK 100 LTE network radio and the SLN 1000 CBRS device. The “B” version (PMLN7560B) that started shipping in November is required.

Motorola Technical Notification: APX/PCR RSM Cable Failures
Remote speaker-microphones cables for APX P25 and XPR MOTOTRBO DMR series radios could experience jacket failures when stressed. A manufacturing change in jacket material caused the problem.
When the cord is stressed the cable could tear or fray and expose the internal wiring. As a result, RSM’s that show failures will be replaced for up to 24 months after purchase.
Symptoms and Root Cause of the Cord Failures
The cord failure is shown in the image. The failure typically occurs at the RSM head or radio connector end or both, but can also occur in cable middle section.
Radio users who prefer to route the mic cord behind their back and stress the cable are more likely to experience the problem. Motorola recommends to dress the coil section so it
does not get caught on uniform accessories for optimal RSM service life.
Motorola Remote Speaker-Microphone Models Affected
Motorola is upgrading the cable jacket material in the near future. RSM’s with the new cable will include an “L” in the model suffix when shipped.
Below are the RSM’s identified in the Motorola Technical Notification (MTN):
APX 8000, APX 7000, APX 6000, APX 4000,
PMMN4062
PMMN4065
PMMN4069
PMMN4083
PMMN4099
MOTOTRBO PCR XPR 3000 and XPR 7000 Series RSM’s
PMMN4071
PMMN4073
PMMN4108
PMMN4024
PMMN4040
PMMN4025
PMMN4046
PMMN4050
Only mics that show the failure will be replaced under the MTN warranty extension. Reference MTN-0070-19-NA and original factory order number when requesting replacements. They can be obtained by calling Motorola at 1-800-422-4210; prompt 1.

Motorola Wireless Microphone FAQ’s and LED Status Indicators
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)

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.
MOTOTRBO XPR 7000 Series With Bluetooth Enabled
- RLN6562 – Operations Critical Wireless Remote Speaker Microphone with Battery and Belt clip and Dual Unit Charger (PMLN7120)

Wireless Mic for APX, XTL, and XPR Series Vehicle Mounted Radios
- RLN6551 – Long Range Wireless Mobile Accessory Kit, includes Wireless
Remote Speaker Microphone (RLN6544), Mobile Microphone Bluetooth Gateway (PMMN4097), Vehicular Charger (PMLN6716) - RLN6552 – Same as above without vehicular charger
