Chassis Unit Replacement Procedure

It is a standard design feature for the switch board to be unfastened within the chassis.
If the switch board appears loose or sinks when pressed, this is not a factory defect. The design requires the board to be pushed out and secured using the screw on the back once the unit is installed in the hilt.
