PHO
OWNER’S MANUAL

CONGRATULATIONS
Congratulations on becoming the owner of a Yamaha PF10 Electronic Piano. The PF10
is a compact, lightweight electronic piano which utilizes Yamaha’s advanced FM sound
source technology to produce beautiful natural-sounding music. Its keyboard contains
76 keys and covers a broad six-octave range, and there are 10 voice selectors-PIANO 1,
PIANO 2, PIANO 3, ELECTRIC PIANO 1, ELECTRIC PIANO 2, ELECTRIC PIANO
3, HARPSICHORD 1, HARPSICHORD 2, VIBRAPHONE, and CLAV-to allow a wide
variety of musical expression. Further, a new touch-type system is used with electric
organ type keys which not only provides key response that is close to that of an acoustic
piano, but easier for beginners to play.
The PF10 also features a built-in amplifier system with dual speakers to produce a rich,
full sound that emanates from the entire instrument rather than just from a single tiny
speaker as in comparable models. Taking full advantage of its dual speaker system, the
PF10 produces a beautiful stereo chorus effect that creates a vibrant multi-instrument
sound.
Please be sure to read this manual thoroughly in order to get maximum enjoyment
from your Yamaha PF10 Electronic Piano.

LOCATION CONNECTION
Avoid placing your electronic piano in direct sunlight or
close to a source of heat. It is also important to avoid
locations in which the instrument is likely to be subjected
to vibration, excessive dust, cold or moisture.
HANDLING
Avoid applying excessive force to the instruments’s knobs
and switches.
POWER CORD
Always grip the power plug directly when unplugging.
Removing the power plug from the wail socket by pulling
on the power cord can result in damage to or shorting of
the power cord.
Be sure to unplug your electronic piano if you will not be
using it for an extended period of time.
RELOCATION
When moving the electronic piano once it has been set up,
be sure to disconnect all cords that connect to other equip-
ment. This will helo prevent accidental damage to or short-
ing of interconnection cables.
Carefully follow the “CONNECTION” instructions given
in this manual when setting up your electronic piano.
Connection errors can lead to serious damage to the instru-
ment, amplifier, and speakers.
CLEANING
Do not use solvents such as benzine or thinner to clean
your electronic piano as these may cause discoloration or
staining of the instrument's exterior. Use a soft, dry cloth.
SAVE THIS MANUAL
After studying this manual thoroughly, it should be stored
in a safe place for future reference.
LIGHTNING
In the event of an electrical storm, the instrument’s power
cord should be unplugged to eliminate the possibility of
serious damage.
OTHER APPLIANCES
Use your electronic piano where its digital circuitry cannot
be influenced by electromagnetic radiation from appliances
such as televisions, radios, etc.

FEATURES AND FUNCTIONS/CONNECTION
Since the Pf10 features a built-in amplifier and speakers, you can begin playing the instrument as soon as you plug in the power
cord and turn on the power switch. In order to become familiar with the operation of the Pf10, follow the procedures outlined
below.

TONE SELECT
SS |
| E E 00000 |
UHAN,
1. Power Cord
Insert the PF10 power plug into the most convenient AC
wall outlet.
2. Power Switch
Push the Power switch located on the far right of the
control panel to the ON position. The power indicator will
light and the PF10 is ready to play.
@ When turning the power off, first turn the VOLUME
control all the down by sliding it to the left position.
Then turn the Power switch off.
@ Check whether the A/B selection switch in the TONE
SELECT panel is in the A position (out). If it is in the B
position (in) press the switch to set it in the A position.
® Depress the TONE SELECT PIANO | switch.
@ Gradually turn the VOLUME control while pressing one
of the PF10's keys and you should hear the correspond-
ing note from the built-in speaker.
e Note loudness can be changed by applying different
amounts of pressure to the key.
3. Connection to an External Speaker System
In order to use headphones or an external speaker system
rather than the built-in speaker system, connect the head-
phones or amp/speaker to the appropriate jack (or jacks) in
the rear panel.
STEREO CHORUS
Power Indicator

Speaker
Keyboard Range
The keyboard range is from EO to G6 (76 keys, 6 octaves),
The maximum number of notes that can be produced
simultaneously is 16.
@ PHONES (phone and mini)
Tow headphones jacks are provided: one stereo phone jack
and a stereo mini jack. Use of stereo headphones allows you
to enjoy a rich stereo listening effect, while other mini
headphones can be plugged into the mini jack for con-
venient private listening to the keyboard.
e When headphones are connected the PF10's enclosed
speakers will be automatically shut off so that no sound
comes out.
B OUTPUT | and OUTPUT Il
Either of these jacks can be used to provide the PF10
output signal to an external power amplifier, integrated
amp/speaker (such as any standard musical instrument
amplifier) or mixer. A speaker with no built-in amplifier
cannot be connected directly to these jacks. A power
amplifier and speaker system or an integrated amp/speaker
must be used.
@ When connecting the PF10 to an external stereo system,
connect the plug to the stereo amp’s AUX terminal.

Although the PF10’s chorus effect is heard if a single
amp-speaker is connected, the full stereo effect can only
be obtained if the OUTPUT 1 and Il jacks are fed to two
independent amp/speaker systems, or two channels of a
mixer that will be assigned to the left and right stereo
program busses.
Output Level = —10 dBm (line level)
Impedance = 600 ohms
© KEY HOLD (FOOT SW.)
An FC-5 foot pedal (supplied) is connected to this jack.
When the foot pedal is depressed, an effect is obtained
similar to that obtained when the sustain pedal of an
acoustic piano is used. If you depress the foot pedal while
pressing a key, the note will be sustained even when you
release the key. The same is true with chords. Since the
sustain effect will be held as long as the foot pedal is
depressed, the sound is cut off when the pedal is released.
@ The above effect is not obtained if the SUSTAIN pedal
is being used as Sustain has priority over KEY HOLD,
@ If you want to obtain this effect for another sound,
release the pedal, press the desired key(s) and depress
the pedal again.
If you depress the KEY HOLD pedal while pressing 16
keys simultaneously, all sixteen notes will be sustained,
so you must release the pedal if you want to produce
other sounds.If, however, you are depressing the foot
peda! to hold only four keys, for example, you can
play 12 other sounds simultaneously.
= External Speaker and Component Connection
O SUSTAIN (FOOT SW.)
Connect the other FC-5 foot pedal to this jack. This foot
pedal permits convenient foot control of the SUSTAIN
on/off function.
e Sustain Effect
By depressing the SUSTAIN foot pedal you obtain the
same effect as that obtained by using the sustain foot
pedal on an acoustic piano—the sound graduaily de-
creases even after you release the key. When you release
the foot pedal, the sound being sustained is immediately
cancelled.
@ The sustain effect is not obtained if the FC-5 foot pedal
is not connected to this jack.
@ LINE INPUT (External Input Jack)
This jack is used to connect an external source such as a
rhythm machine, cassette deck, or other keyboard to play
through the PF10. Thus you can mix the sounds produced
by the PF10 with these other sources to expand the range
of your musical enjoyment.
e Since the volume of the external component cannot be
controlled by the PF10's volume control, adjustments
must be made on the external component.
e Only one LINE INPUT jack is provided. To connect a
stereo source, plug in either the L or R output line.
The monaural signal will be heard simultaneously from
both of the PF10's built-in speakers.

O PITCH (Pitch Control)
Turning this control clockwise raises the instrument's
overall pitch, while turning it counterclockwise lowers the
overall pitch. Standard pitch of 440 Hz (A3) is obtained
when the control is set slightly to the left of its center
position. Control range is from 436 to 447 Hz.
@ VOLUME
Adjusts the overall volume of the PF10's sound.
@ When using an external amplifier and speaker system,
setting the external amplifier volume control so that the
most comfortable overall volume is obtained when the
PF10's VOLUME control is set to about “8” results in
the best sound quality.
© STEREO CHORUS
This switch turns the PF10’s vibrant stereo chorus effect
ON or OFF.
e The chorus effect is not produced on sounds coming
through the PF10 from external components.
O TONE SELECT
These switches determine the basic PF10 sound. There are
10 basic selections: PLANO 1, 2 and 3, HARPSICHORD 1
and 2, ELECTRIC PIANO 1, 2 and 3, VIBRAPHONE
and CLAV. When the A/B selection switch is in the A
position (L) the sounds written on the upper line are
obtained for each TONE SELECT switch. When in the B
position (=), the sounds written on the lower line are
obtained. Choose the sound you want using the A/B
selection switch and the appropriate TONE SELECT
switch.
e lf all the TONE SELECT switches are off, PIANO 1 is
automatically selected.
@ To change the sound, wait until the present sound
completely disappears before pressing the next TONE
SELECT switch to avoid erroneous sound selection.
@ if two or more TONE SELECT switches are pressed at
the same time, the switch on the right is selected auto-
matically.

@ KEY TRANSPOSE
While the keyboard has exceptional range thanks to its 76
keys and six octave range, even further versatility is pro-
vided by the KEY TRANSPOSE function, which allows
you to adjust the sounds of the keys another half-octave
up and down. Thus you can have a full octave more of
sound, and all sounds are adjusted accordingly.
e For normal operation, the KEY TRANSPOSE lever is
set in the “C” position.
fa do mi
When the KEY TRANSPOSE lever is placed in the ''C'' position,
this key produces the sound “do”,
When the lever is in the ''E'' position, this key produces the
sound ''mi''.
When the lever is in the “A” position, this key produces the
sound ''la''.
