NOTE
When powering on the GR4000－320E (AC), setting all its power switches to ON should be done
within 8 seconds. If you cannot do it within 8 seconds, there is the possibility that the BCU
signals a temporal abnormality related to the status of power sources. However, the system gets
back to normal after all the switches are set to ON.
