NOTE

Connection is lost when there is no communication between the Display and the External Device after 9 seconds. A time-out error is displayed as the connection is lost, when the Display tries to reconnect. The time-out error is restored automatically.
To prevent the time-out error from being displayed, make the settings so that communication may be performed in a shorter cycle than the specified time-out for connection, using a watchdog timer, and etc.
