The Motorola RKN4155 Computer Programming Software (CPS) Cable - The RDX and CP110 series radios have the capability to be programmed by using the CPS cable.
CPS allows you to program features like frequencies, PL/DPL codes, bandwidth, time-out timer, power select, battery type select, scan list, call tones, scramble, etc. Your CPS cable will help you read and modify these kinds of features in your radio.
Note! Before using the CPS, make sure you disconnect the power supply from the drop-in tray charger.
