— Cautions regarding the update (Important!) ———————————-

* Don’t use this system for any product other than the MC-909. Doing so may damage the data or system of the other product.

* We recommend that you save your user data before performing the update. If an unexpected accident causes the user data to be lost, you can restore the MC-909 to its previous condition by reloading the data you saved. Refer to the owner’s manual for the procedure.

* Never turn off the power of the MC-909 while the update is in progress. If the power is accidentally turned off during this process, the MC-909’s system will be destroyed, rendering the unit inoperable.
