Before Requesting A/S Service
It is required for users to back up important data regularly from storage device (to other separate media). Depending on the situation, it will be necessary to delete the
data from the internal storage device (component). It might be needed to delete all the data from the product for A/S. So it is required for users to back up important
data by themselves before requesting A/S. For all the A/S products, it is regarded that the user already backed up the data so there is no additional back-up process.
Therefore, it is important to note that we are not responsible for any data lost during A/S.
