•
If multiple keys fail to work, a problem in the A52 Front Panel I/F board or
A60 CPU Module is suspected. Also, check the flat cable between the A52
Front Panel I/F board and A60 CPU Module.
• If only a specific key fails to work, check first if the key is subsided in the
panel.
•
If the rotary knob fails to work, check the A52 Front Panel I/F board
involving the RPG.
To Check the Touch Panel
Procedure
Using the LCD display panel, select or change the setting of a function in the
softkey menu and then, perform the same operation using the hardkeys.
• If the touch panel does not work correctly when the hardkeys function
normally, a failure seems to be in the touch screen controller assembly or
touch-panel LCD assembly. (The touch panel is not replaceable
independently of the LCD.)
• Check the cable between the touch screen controller and the serial
interface connector on the A60 CPU module.
• If no problem is found in the above checks, a failure in the A60 CPU Module
is suspected.
