Insert the keyboard sheet between the keyboard cover and the cabinet as illustrated below.
• Do not spread the keyboard cover too far as it might tear the tabs.
• Replace the keyboard sheet with a new one if by chance it gets wet. Use of a wet keyboard
sheet may cause problems.
• Be sure to use only SHARP-supplied keyboard sheets. Thick or hard sheets can make key
operations difficult.
• Place the keyboard sheet evenly under the keyboard cover.
• If you require a new keyboard sheet, please contact your dealer.
• The keyboard cover will eventually wear out. If your keyboard cover is dirty or broken, replace the
cover with a new one. For details, contact your authorized SHARP dealer.
