Precautions —
Taking Care of Your PortaTone
Your new PortaTone is a fine musical instrument — and should be treated as such. Handle it with care and
common sense, and it will give you years of enjoyment.
Location ------------------------------------------------------------------
• Avoid exposure to direct sunlight or other sources of heat. Never leave it inside a car where it can get
very hot. Also avoid highly humid or dusty places.
Interference From Electromagnetic Fields------------------------
• Do not use your PortaTone close to television sets, radios or similar equipment since this may cause
interference noise in the other appliance.
Handling ----------------------------------------------------------------
• Protect your PortaTone from strong impact. Be careful not to drop it or place heavy objects on it.
Avoid applying excessive force to the controls and keys.
• Always unplug cables by gripping the plug firmly, and not by pulling on the cable.
Turn Power Off When Making Connections --------------------
• To avoid damage to the PortaTone or other equipment, turn off the power of all related equipment —
including the PortaTone — before connecting or disconnecting any cables.
When Not Using the PortaTone ------------------------------------
• After use, always turn off the POWER switch. When not using your PortaTone for long periods, be sure
to remove the batteries to avoid damage through battery leakage. When using the PortaTone with an AC
adaptor, unplug the adaptor from the electrical outlet, if the instrument is not to be used for a long period
of time, or during electrical storms.
Cleaning------------------------------------------------------------------
• Clean the exterior with a soft, dry cloth. To remove stubborn stains, use a slightly moistened cloth.
• Never use alcohol, thinner, or other chemical solvents, since they will damage the finish. Also, do not
leave vinyl chloride material on the PortaTone for a long time, since it may adhere to the exterior.
Service and Modification --------------------------------------------
• Your PortaTone contains no user-serviceable parts. Opening it or tampering with it in any way may
result in damage and even electrical shock. Refer all servicing to qualified Yamaha personnel.
• Yamaha is not responsible for damage caused by improper usage.
