Battery Disconnection



The DATC will store the panel settings in volatile memory. Therefore, in the event of battery disconnection, or interruption of the supply, the information is lost. After reconnection, historical fault codes are available, and the panel will be set to OFF. An average automatic setting will be recovered when the DATC is next switched ON.

If the battery is disconnected, the panel settings will be lost. The customers non standards settings should be recorded and re-inputed before the vehicle is returned to the customer.
