Procedure
Observe ESD precautions when working inside your KX3. Wear an ESD wrist strap or touch an
unpainted, metal ground frequently while working.
Separating the KX3 Case Halves
Open the KX3 just as you would to install or remove batteries (see Internal Batteries in your Owner’s
Manual for details about how to do this).
If batteries are installed, remove them.
Disconnect the flex cable and the battery cable as shown in Figure 1. The owner’s manual cautions against
disconnecting the flex cable. That is because the connectors on the flex cable are not designed for heavy use. It is
necessary to disconnect the ribbon cable in this case. Gently work the connectors loose holding the stiff section
attached to each connector. Do not pull on the ribbon cable itself.

Set the bottom cover assembly aside in a safe place.
