PRECAUTIONS
■ AVOID EXCESSIVE HEAT,
HUMIDITY, DUST AND VIBRATION
Keep the unit away from locations where it is
likely to be exposed to high temperatures (such
as direct sunlight) or humidity. Also avoid
locations which are subject to excessive dust
accumulation or vibration which could cause
mechanical damage.
■ DO NOT OPEN THE CASE OR
ATTEMPT REPAIRS OR
MODIFICATIONS YOURSELF
This product contains no user-serviceable parts.
Refer all maintenance to qualified Yamaha
service personnel. Opening the case and/or
tampering in any way with the internal circuitry
will void the warranty.
■ MAKE SURE POWER IS OFF
BEFORE MAKING OR REMOVING
CONNECTIONS
Always turn the power off prior to connecting
or disconnecting cables.
■ HANDLE ALL CONNECTIONS
CAREFULLY
Always be careful to connect and disconnect all
cables and cords by gripping the connector
itself, not by pulling on the cord.
■ CLEAN WITH A SOFT, DRY CLOTH
Never use solvents such as benzine or thinner to
clean the unit, since these will damage the
finish. Wipe clean with a soft, dry cloth. If
necessary, use a soft, clean cloth slightly mois-
tened with a diluted, mild detergent — making
sure to wipe the case off again with a dry cloth.
■ ELECTRICAL INTERFERENCE
Since the GW50 contains digital circuitry, it
may cause interference and noise if placed too
close to TV sets, radios or similar equipment. If
such a problem occurs, move the GW50 further
away from the affected equipment.
■ MIDI CABLES
When connecting the GW50 to other MIDI
equipment, be sure to use only high-quality
cables made especially for MIDI data transmis-
sion. Also avoid cables longer than 15 meters,
since long cables can result in data errors.
