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 not compatible with the WAVE PTT TLK 100 LTE network radio or the SLN 1000 CBRS device yet. There is a “B” version due out in December that will include them. The RM250 “A” version is available now and can be ordered online.
