"The RM Series is full-featured FM transceivers designed for flexible mobile and base station business communications in the UHF Land mobile frequency bands. The RM Series mobile radios can be programmed with 128 channels. The RM Series include a 16 segment, 8 character, alphanumeric display for channel display.
