2. Note for servicing and handling
When the main unit power is repeatedly turned OFF/ON rapidly (for about 1sec), the IC (OA982) on the MCU PWB may malfunction to cause an error
(E1-00 Communication error), which does not boot the machine. In case of this error, the blank display is kept for several tens seconds and then "E1-
00" is displayed on the panel display.
(E1-00 Communication error), which does not boot the machine. In case of this error, the blank display is kept for several tens seconds and then "E1-
00" is displayed on the panel display.
<Countermeasure>
Turn off the power and keep it for more than 10sec. Then turn on the power.
When the machine is booted.: There is no problem in the MCU PWB.
When the machine is not booted.: The MCU PWB trouble
