In this unit, about 10 seconds after power is supplied to the battery terminal using the regulated power supply (8.4 Vdc), the power is shut off 
so that the unit cannot operate.
These following method is available to prevent this.

Note the following when replacing the board.

When you replace to the repairing board, the written destination data of repairing board also might be changed to original setting.
Start the Adjust Manual in the Adjust Station and execute the “DESTINATION DATA WRITE”.

The set is shipped with a unique ID (USB Serial No.) written in it.
This ID has not been written in a new board for service, and therefore it must be entered after the board replacement.
Start the Adjust Manual in the Adjust Station and execute the “USB SERIAL No. INPUT”.

The unit is shipped after an ID (PRODUCT ID) unique to each model has been written.
This ID is not written to a new replacement board. Enter a unique ID after the board has been replaced.
