Tyros3
REPLACING THE INTERNAL HARD DISK
If the factory-installed hard disk crashes or when you want to replace it with another one (for example, one you have used on the Tyros/
Tyros2), you can remove the current one and install the new one by following the procedure below. The hard disk used must be a 2.5-inch
P-ATA (parallel ATA) compatible; however, not all such drives may be installable.
WARNING
• Before beginning, switch off the power to the Tyros3 and connected peripherals, and unplug them from the power outlet.
Then remove all cables connecting the Tyros3 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. 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 hard disk units carefully as described in the procedure below. Improper installation can cause shorts which
may result in irreparable damage and pose a fi re hazard.
• Do not disassemble, modify, or apply excessive force to board areas and connectors on hard disk units. Bending or
tampering with boards and connectors may lead to electric shock, fi re, or equipment failures.
CAUTION
• Before removing the installed hard disk unit, make sure to backup any necessary data on the disk to computer by using
the USB Storage Mode. This will prevent loss of important data and enable you to use the data on the new hard disk. (If
you need to backup the recorded audio fi les, save the hidden folder "HDR.ROOT" to the computer.)
• It is recommended that you wear gloves to protect your hands from metallic projections on hard disk units and other
components. Touching leads or connectors with bare hands may cause fi nger cuts, and may also result in poor electrical
contact or electrostatic damage.
• Handle the 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 or the instrument.
Before you handle the 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.
NOTE
• Hard disk drives thicker than 12.7 mm cannot be installed to the Tyros3.
• S-ATA compatible hard disks cannot be used.
Before following the steps below, make sure you have an ap-
propriate hard disk drive and a Phillips screwdriver.
