Information - Motorola RDU4100 Radio

The Motorola RDU4100 radio has been replaced with the Motorola CP100d-UA radio.

  • CP100d radios are not programmed to work out of the box on default RDX frequencies.
  • The CP100d can be programmed to match RDX frequencies, or any custom frequencies, by using CPS2.0 Lite, which is free Motorola programming software designed to work with all CP100d analog only radios.
  • CPS2.0 Lite can be downloaded along with default RDX frequency programming templates.
  • We can program CP100d radios to RDX default frequencies. A $10 tech fee will be charged for each programmed radio.
  • CP100d analog only models can be upgraded to analog/digital operation for a fee.
