Description of Responsibilities

Please back up your personal data before sending your device for repair. The repair process may result in the loss of your personal data. While BKHD will protect your privacy, we cannot take responsibility for any damage or loss of personal data during the repair process.

When the unit is sent for repair, it must be inspected by the BKHD service department. After confirming the malfunction, the service department will determine the appropriate repair plan. For products under free warranty, the BKHD customer service department may choose to provide you with the warranty service promised in this document by replacement, repair, or other methods. If the replacement method is chosen, the replaced defective parts belong to BKHD. Products that are found to have no problems upon inspection will be returned as is.

If the product does not meet the warranty conditions and a fee must be charged, the BKHD customer service department will charge the consumer a repair fee and state the reason for not meeting the warranty conditions on the invoice or receipt.
