PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep these precautions in a safe place for future reference.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from electrical shock,
short-circuiting, damages, fire or other hazards. These precautions include, but are not limited to, the following:
• Do not open the instrument or attempt to disassemble the internal parts or modify
them in any way. The instrument contains no user-serviceable parts. If it should
appear to be malfunctioning, discontinue use immediately and have it inspected by
qualified Yamaha service personnel.
• Do not expose the instrument to rain, use it near water or in damp or wet conditions,
or place containers on it containing liquids which might spill into any openings.
• If the AC adaptor cord or plug becomes frayed or damaged, or if there is a sudden
loss of sound during use of the instrument, or if any unusual smells or smoke
should appear to be caused by it, immediately turn off the power switch, disconnect
the adaptor plug from the outlet, and have the instrument inspected by qualified
Yamaha service personnel.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the
instrument or other property. These precautions include, but are not limited to, the following:
• Do not place the AC adaptor cord near heat sources such as heaters or radiators,
and do not excessively bend or otherwise damage the cord, place heavy objects on
it, or place it in a position where anyone could walk on, trip over, or roll anything
over it.
• When removing the electric plug from the instrument or an outlet, always hold the
plug itself and not the cord.
• Do not connect the instrument to an electrical outlet using a multiple-connector.
Doing so can result in lower sound quality, or possibly cause overheating in the
outlet.
• Unplug the AC power adaptor when not using the instrument, or during electrical
storms.
• Always make sure all batteries are inserted in conformity with the +/- polarity
markings. Failure to do so might result in overheating, fire, or battery fluid leakage.
• Always replace all batteries at the same time. Do not use new batteries together
with old ones. Also, do not mix battery types, such as alkaline batteries with
manganese batteries, or batteries from different makers, or different types of batteries
from the same maker, since this can cause overheating, fire, or battery fluid leakage.
• Do not dispose of batteries in fire.
• Do not attempt to recharge batteries that are not intended to be charged.
• When the batteries run out, or if the instrument is not to be used for a long time,
remove the batteries from the instrument to prevent possible leakage of the battery
fluid.
• Keep batteries away from children.
• If the batteries do leak, avoid contact with the leaked fluid. If the battery fluid should
come in contact with your eyes, mouth, or skin, wash immediately with water and
consult a doctor. Battery fluid is corrosive and may possibly cause loss of sight or
chemical burns.
• Before connecting the instrument to other electronic components, turn off the power
for all components. Before turning the power on or off for all components, set all
volume levels to minimum. Also, be sure to set the volumes of all components at
their minimum levels and gradually raise the volume controls while playing the
instrument to set the desired listening level.
• Use the specified adaptor (PA-3B, PA-3, PA-4, PA-40 or an equivalent
recommended by Yamaha) only. Using the wrong adaptor can result in damage
to the instrument or overheating.
• Before cleaning the instrument, always remove the electric plug from the outlet.
Never insert or remove an electric plug with wet hands.
• Check the electric plug periodically and remove any dirt or dust which may
have accumulated on it.
• Do not expose the instrument to excessive dust or vibrations, or extreme cold or
heat (such as in direct sunlight, near a heater, or in a car during the day) to prevent
the possibility of panel disfiguration or damage to the internal components.
• Do not use the instrument near other electrical products such as televisions, radios,
or speakers, since this might cause interference which can affect proper operation
of the other products.
• Do not place the instrument in an unstable position where it might accidentally fall
over.
• Before moving the instrument, remove all connected adaptor and other cables.
• When cleaning the instrument, use a soft, dry cloth. Do not use paint thinners,
solvents, cleaning fluids, or chemical-impregnated wiping cloths. Also, do not
place vinyl, plastic or rubber objects on the instrument, since this might discolor
the panel or keyboard.
• Do not rest your weight on, or place heavy objects on the instrument, and do not
use excessive force on the buttons, switches or connectors.
• Use only the stand/rack specified for the instrument. When attaching the stand or
rack, use the provided screws only. Failure to do so could cause damage to the
internal components or result in the instrument falling over.
• Do not operate the instrument for a long period of time at a high or uncomfortable
volume level, since this can cause permanent hearing loss. If you experience any
hearing loss or ringing in the ears, consult a physician.
Yamaha cannot be held responsible for damage caused by improper use or modifications
to the instrument, or data that is lost or destroyed.
Always turn the power off when the instrument is not in use.
Make sure to discard used batteries according to local regulations.

Getting Started
Power Requirements
Although the PSR-74 will run either from an optional AC
adaptor or batteries, Yamaha recommends use of an AC
adaptor whenever possible. An AC adaptor is more
environmentally friendly than batteries and does not
deplete resources.
Using an AC Power Adaptor
To connect your PSR-74 to a wall socket, you will need the
optionally available Yamaha PA-3/3B/4/40 Power Adaptor.
Use of other AC adaptors could result in damage to the
instrument, so be sure to ask for the right kind. Connect
one end of the adaptor to the DC IN 10-12V jack on the
rear panel of your PSR-74, and the other end to a suitable
electrical outlet.

● When the Batteries Run Down
When the batteries run low and the battery voltage drops
below a certain level, the PortaTone may not sound or
function properly. As soon as this happens, replace them
with a complete set of six new batteries.
CAUTION
Never mix old and new batteries or different types of batteries
(e.g., alkaline and manganese).
CAUTION
To prevent possible damage from battery leakage, remove tg£
batteriT from the instrument if it is not to be used for a long time.
● Auto Power OFF
The PSR-74 features an Auto Power OFF function that
automatically turns the power OFF if the instrument is not
used for approximately 30 minutes. This functions
whether batteries or the AC power adaptor is used.
WARNING
Use ONLY the Yamaha PA-3/3B/4/40 AC Power Adaptor (or other
adaptor specifically recommended by Yamaha) to power your
instrument from the AC mains. The use of other adaptors may
result in irreparable damage to both the adaptor and the PSR-74.
CAUTION
Unplug the AC Power Adaptor when not using the PSR-74, or
during electrical storms.
Using Batteries
● Inserting Batteries
Turn the instrument upside-down and remove the battery
compartment lid. Insert six 1.5-volt size “D” batteries as
shown in the illustration, making sure that the positive and
negative terminals are properly aligned. Replace the lid.
Accessory Jacks
Using Headphones
For private practicing and playing without disturbing
others, connect a set of stereo headphones to the rear
panel PHONES/OUTPUT jack. Sound from the built-in
speaker system is automatically cut off when you insert a
headphone plug into this jack.
