PLEASE NOTE: MOTOROLA RADIUS RADIOS have been discontinued by Motorola but are 100% communication compatible with the new Motorola RM Series. We still have M-series accessories available.
Expand your two-way radio system without having to buy all new radios! If you own a Motorola Radius SP50 or another Motorola Radius model, these walkie-talkies are compatible with other Motorola models. This lets you add new radios to your system while keeping older radios in service for a more cost-effective solution to growing communication needs.
