Four pack of Motorola RMM2050 radios with programming video primer made by All Charged Up on packing slip included with radios. Each of our radios comes complete with a single-unit charger, 15 hour lithium ion battery pack, swivel belt holster, 1-year warranty, free shipping, and guaranteed support from our team of radio experts. Radios work right out of the box with the default RMM2050 programming, but the programming video gives instructions for how to optionally customize your frequency and privacy code to get rid of any possible cross-talk and ensure private and secure communication. For questions, give us a call or shoot us an email.
