(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 installa- tion. (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 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. • Be careful of static electricity. Static electricity discharge can damage the IC chips on the DIMM. Before you handle the optional DIMM, to reduce the possibility of static electricity, touch unpainted metal parts or a ground wire on the devices that are grounded. • Handle the optical units with care. Dropping or subjecting them to any kind of shock may cause damage or result in a malfunction. • 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. • Do not use any screws other than what are installed on the instrument. Use of incorrect screws can cause damage.
