1. CANCELING DETECTION BY THE TRAP SWITCH
� Canceling detection by the TRAP switch
For video data transmission from the HDMI input to the plasma display, digital signals are used. Therefore, this unit adopts the HDCP (High-bandwidth Digital Content Protection) system for copyright protection. This unit is also provided with a detection switch (TRAP switch) that will prohibit the unit from being turned on again if the rear case of the unit is opened, in order to prevent the panel technology from being leaked out. Function: To deactivate the detection of the TRAP switch Purposes: 1. During production of this unit, adjusting with the rear cover opened is possible. 2. During servicing or repairing, diagnoses of the assemblies are possible while the power is on. Methods: For setting, use RS232C commands: TSN: Ignore the monitoring of the switch CTM: Clear the detection log of the switch TSY: Reactivate monitoring of the switch Notes:
� � � � The TRAP switch is located on the chassis (see Fig.2 below). Once rear case opening is detected, send the TSN and CTM commands. Because the TSN command is not stored in memory, monitoring of the switch can be reactivated by turning the unit off then back on. The same setting is possible using the Factory menu.
