Appendix Installing an Optional Hard Disk By installing an optional hard disk drive to the TYROS, you can vastly expand the data storage capacity - letting you create a large library of your important data, without having to worry about a lack of memory space. The hard disk used must be a 2.5-inch IDE-compatible; however, not all such drives may be installable. • Before beginning installation, switch off the power to the TYROS and connected peripherals, and unplug them from the power outlet. Then remove all cables connecting the TYROS to other devices. (Leaving the power cord connected while working can result in electric shock. Leaving other cables connected can interfere with work.) • Be careful not to drop any screws inside the instrument during installation (this can be prevented by keeping the optional units and cover away from the instrument while attaching). If this does happen, be sure to remove the screw(s) from inside the unit before turning the power on. Loose screws inside the instrument can cause improper operation or serious damage. If you are unable to retrieve a dropped screw, consult your Yamaha dealer for advice. • Install the optional units carefully as described in the procedure below. Improper installation can cause shorts which may result in irreparable damage and pose a fire hazard. • Do not disassemble, modify, or apply excessive force to board areas and connectors on optional hard disk units. Bending or tampering with boards and connectors may lead to electric shock, fire, or equipment failures. • It is recommended that you wear gloves to protect your hands from metallic projections on optional units and other components. Touching leads or connectors with bare hands may cause finger cuts, and may also result in poor electrical contact or electrostatic damage. • Handle the optional hard disk unit with care. Dropping or subjecting them to any kind of shock may cause damage or result in a malfunction. • Be careful of static electricity. Static electricity discharge can damage the IC chips on the hard disk. Before you handle the optional hard disk, to reduce the possibility of static electricity, touch the metal parts other than the painted area or a ground wire on the devices that are grounded. • Do not touch the exposed metal parts in the circuit board. Touching these parts may result in a faulty contact. • Be careful not to misplace any of the screws since all of them are used. • Do not use any screws other than what are installed on the instrument. • Hard disk drives wider than 12.7 mm cannot be installed to the TYROS. • For information on the hard disk recommendations, ask your nearest Yamaha representative or an authorized distributor listed at the end of this owner's manual. Install a hard disk at your own risk. Yamaha will not be held responsible for any damage or injury resulting from improper installation or the use of a hard disk other than one of the types recommended by Yamaha. Before following the steps below, make sure you have an appropriate hard disk drive and a Phillips screwdriver. 1 Turn the TYROS' power off, and disconnect the AC power cord. Also, make sure to disconnect the keyboard from any other external devices. 2 Turn the TYROS face down on a blanket or some soft surface, giving you direct access to the bottom of the instrument. Never open! Cover 3 Remove the eight screws from the cover. Do not remove the other screws. Use this as a handle to remove the cover. 4 Remove the four screws from the hard disk cover inside. 162 TYROS Owner's Manual 160
