Taking Care Of Your Portatone - Yamaha PSR-520 Product Manual

Taking Care of Your PortaTone

Your PortaTone will give you years of playing pleasure if you follow the simple rules given below:
Location
Do not expose the instrument to the following
conditions to avoid deformation, discoloration, or
more serious damage.
Direct sunlight (e.g. near a window).
High temperatures (e.g. near a heat source, out-
side, or in a car during the daytime).
Excessive humidity.
Excessive dust.
Strong vibration.
Power Supply
Turn the power switch OFF when the instrument
is not in use.
An AC adaptor, if used (the PSR-520 runs from
either batteries or an optional AC adaptor),
should be unplugged from the AC outlet if the
instrument is not to be used for an extended pe-
riod of time.
Unplug the AC adaptor during electric storms.
Avoid plugging the AC adaptor into the same AC
outlet as appliances with high power consump-
tion, such as electric heaters or ovens. Also avoid
using multi-plug adaptors since these can result
in reduced sound quality, operation errors, and
possibly damage.
Turn Power OFF When Making
Connections
To avoid damage to the instrument and other
devices to which it is connected, turn the power
switches of all related devices OFF prior to con-
necting or disconnecting MIDI cables.
Handling and Transport
Never apply excessive force to the controls, con-
nectors or other parts of the instrument.
Always unplug cables by gripping the plug
firmly, not by pulling on the cable.
Disconnect all cables before moving the instru-
ment.
Physical shocks caused by dropping, bumping,
or placing heavy objects on the instrument can
result in scratches and more serious damage.
Cleaning
Clean the cabinet and panel with a dry soft cloth.
A slightly damp cloth may be used to remove
stubborn grime and dirt.
Never use cleaners such as alcohol or thinner.
Avoid placing vinyl objects on top of the instru-
ment (vinyl can stick to and discolor the sur-
face).
Electrical Interference
This instrument contains digital circuitry and
may cause interference if placed too close to
radio or television receivers. If this occurs, move
the instrument further away from the affected
equipment.
Data Backup
Internal data (registration memory, user song and
user pad data) will be retained in memory even if
the power switch is turned OFF as long as an AC
power adaptor is connected or batteries are in-
stalled.
Service and Modification
The PSR-520 contains no user serviceable parts.
Opening it or tampering with it in anyway can
lead to irreparable damage and possibly electric
shock. Refer all servicing to qualified YAMAHA
personnel.
YAMAHA is not responsible for damage caused by improper handling or operation.
