Taking Care Of Your Portatone - Yamaha PortaTone PSR-1700 Owner's 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.
• The power cord should be unplugged from the
AC outlet if the instrument is not to be used for
an extended period of time.
• Unplug the instrument during electric storms.
• Avoid plugging the instrument 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 and possibly damage.
Turn Power OFF When Making
Connections
• To avoid damage to the instrument and other
devices to which it is connected (a sound system,
for example), turn the power switches of all re-
lated devices OFF prior to connecting or discon-
necting audio and 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 re-
sult 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 surface).
Electrical Interference
• This instrument contains digital circuitry and
may cause interference if placed too close to ra-
dio or television receivers. If this occurs, move
the instrument further away from the affected
equipment.
Service and Modification
• The PSR-1700/PSR-2700 contains no user serv-
iceable parts. Opening it or tampering with it in
anyway can lead to irreparable damage and pos-
sibly electric shock. Refer all servicing to quali-
fied YAMAHA personnel.
Data Backup
• Internal data (e.g. Song Memory data) is retained
in memory even if the power switch is turned off
as long as backup batteries are installed (page 5)
or the AC plug is connected. The internal
memory can, however, be corrupted by incorrect
operation. Be sure to save important data to
floppy disk frequently so you have a backup to
revert to if the data in memory is accidentally
damaged. Also note that magnetic fields can
damage data on floppy disks, so it is advisable to
make a second backup copy of disks that contain
particularly important data. Always keep backup
disks in a safe place away from stray magnetic
fields (e.g. those produced by speakers, appli-
ances containing motors, etc.). More important
precautions for floppy disk use are given in the
"Floppy Disk" section beginning on page 56.
YAMAHA is not responsible for damage caused by improper handling or operation.
