Precautions

Keep the unit away from locations where it is likely to be exposed to high tem-
peratures or humidity — such as near radiators, stoves, etc. Also avoid loca-
tions which are subject to excessive dust accumulation or vibration which could
cause mechanical damage.
Strong physical shocks to the unit can cause damage. Handle it with care.
This product contains no user-serviceable parts. Refer all maintenance to qual-
ified Yamaha service personnel. Opening the case and/or tampering with the
internal circuitry will void the warranty.
Always turn the power OFF prior to connecting or disconnecting cables.
Always plug and unplug cables by gripping the connector, not the cord.
Never use solvents such as benzine or thinner to clean the unit. Wipe clean with
a soft, dry cloth.
Always use the supplied AC Adaptor to power your RY30 or, if the original
adaptor is lost or broken, a replacement or equivalent type obtained from your
Yamaha dealer. Also, make sure that the adaptor you have is appropriate for the
AC mains supply voltage in the area where you intend to use the RY30 (the
correct INPUT voltage is marked on the adaptor).
Since the RY30 contains digital circuitry, it may cause interference and noise if
placed too close to TV sets, radios or similar equipment. If such a problem does
occur, move the RY30 further away from the affected equipment.
When connecting to RY30 to MIDI equipment, be sure to use high-quality
cables made especially for MIDI data transmission. Also avoid cables longer
than about 15 meters, as longer cables can pick up electrical noise that can
causes data errors.
