The Disassembly of a Motorola Radius CP200

Save

The Motorola Radius CP200 is a handheld radio often used in the construction and maintenance industries. It allows users within 100 feet of each other to communicate with each other clearly, even through wood, stone or concrete walls and floors. If your Motorola Radius CP200 stops working, you can take it apart to repair it yourself. However, you can easily damage the radio if you are not careful and Motorola will not honor any warranty on the unit once you disassemble it.

Battery Compartment

  • Turn the Motorola CP200 off using the knob at the top of the radio. Failing to turn the unit off before removing the battery can cause a short. Turn the radio over and slide the battery lock to the side. Remove the battery case. Push the battery off the unit with your thumbs. Remove the two Phillips screws that are exposed when you remove the battery. These screws hold the two pieces of the Motorola CP200 case together.

Antenna

  • The Motorola Radius CP200 antenna receives and sends radio signals in the 403–512MHz range. Because the antenna is attached to both sides of the radio case, you cannot open it if you do not remove the antenna. Turn the antenna counterclockwise to unscrew it from the unit.

Accessing the Circuit Board

  • A disconnected wire or blown fuse on the circuit board is a common source of problems. The circuit board of the Motorola Radius CP200 is protected by the plastic outer case and internal metal casing. To access the circuit board, pull the two pieces of the Motorola CP200 case apart to expose the metal casing. Remove the four Phillips screws securing the metal casing and pull it out of the unit to expose the circuit board.

Accessing the Speaker and Microphone

  • Remove the four screws securing the circuit board to the rest of the unit. Pull it away from the body of the radio to expose the speaker and microphone attached to the other side. The wires for these components are soldered to the circuit board but you must be careful to avoid inadvertently disconnecting them. You must use a soldering iron to reconnect any broken wires.
