Functions of the mechanism under the service mode
With the three error modes stored in maximum in the internal memory of the mechanism in the body of this
system, it is posible under the service mode to call the contents of error according to the following steps when
any error has occurred.
Press the three buttons (UP button
)+(
button)+(Func button
). Then it is possible to select the follwing
and DOWN button to
service modes. After changing over to the service mode, press the UP button
change the mode. For executing the respective service modes, press the SEL button.
With the service mode 2 , it is possible to call the error codes of the mechanism.
NORMAL MODE
(UP button
) + (
button) + (
button) at the same time.
