Precautions - Yamaha CBX-K1 Owner's Manual

Precautions

Your CBX-K1 will give you years of reliable service if you
follow the simple precautions below:
LOCATION
Keep the instrument 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
damage the instrument.
USE THE CORRECT POWER ADAPTOR
Use only the recommended PA-1B or PA-3 Power Adaptor
for supplying power. Use of another adaptor may cause
serious damage to the instrument or the adaptor itself. Also
avoid using a multiple-plug adaptor; plug the adaptor
directly into a wall outlet.
MAKE SURE POWER IS OFF WHEN MAKING
OR REMOVING CONNECTIONS
To prevent damage to the instrument and other connected
equipment, always turn off the power prior to connecting or
disconnecting cables. Also, turn the power off when the
instrument is not in use, and disconnect the power adaptor
during electric storms.
NO MEMORY BACKUP
The CBX-K1 has no internal memory backup. As a result,
all settings are returned to the factory default when turning
the power off.
HANDLE THE INSTRUMENT WITH CARE
Although the instrument has been constructed to withstand
the rigors of normal use for optimum sturdiness and
reliability, avoid subjecting it to strong physical shocks
(such as dropping or hitting it). Since the CBX-K1 is a
precision-made electronic device, also avoid applying
excessive force to the various controls. When moving the
instrument, first unplug the power adaptor and all other
cables to prevent damage to cords and jacks. Always
unplug cables by gripping the plug firmly, not by pulling
on the cable.
CLEAN WITH A SOFT, DRY CLOTH
Never use solvents such as benzine or thinner to clean the
instrument, since these will damage the cabinet finish or
dull the keys. Wipe clean with a soft, dry cloth. If neces-
sary, use a soft, clean, slightly moistened cloth — making
sure to wipe the instrument off again with a dry cloth. Do
not leave vinyl on the panel as this may stick to and
discolor the surface.

ELECTROMAGNETIC INTERFERENCE
Avoid using the unit near televisions, radios or other
equipment generating electromagnetic fields. Proximity to
such equipment may cause the unit to malfunction, and may
generate interference noise in the other appliance as well.
DO NOT OPEN THE CASE OR TRY REPAIRING
THE INSTRUMENT YOURSELF
The instrument contains no user-serviceable parts. Never
open the case or tamper with the internal circuitry in any
way, since doing so may result in damage to the instrument.
Refer all servicing to qualified Yamaha service personnel.
MIDI CABLES
When connecting the instrument to other MIDI equipment,
be sure to use only high-quality cables made especially for
MIDI data transmission. Also, avoid using cables longer
than 15 meters, since long cables can result in data errors.
Yamaha is not responsible for damage caused by
improper handling or operation.
