Your PortaTone will give you years of playing pleasure if you follow the simple rules given below:
Taking Care of Your PortaTone
■ 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-320/420 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
● 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 surface).
■ 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 and song
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 installed.
■ Service and Modification
● The PSR-320/420 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.
● 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.
YAMAHA is not responsible for damage caused by improper handling or operation.

1 POWER Switch ............................ page 8
This section contains information about setting up your PSR-320/
420 and preparing to play. Be sure to go through this section
carefully before using your PSR-320/420.
Power Supply
Your PSR-320/420 will run either from batteries or an optional power adaptor. Follow the instructions below according to the power source you intend to
use.
■ Using An Optional AC Power Adaptor .............................................................
Plug the DC output cable from an optional Yamaha PA-5, PA-5B, or PA-
5C AC Power Adaptor into the DC IN jack on the rear panel of the PSR-
320/420, then plug the Power Adaptor (or the AC cable of the Power Adap-
tor) into a convenient wall AC power socket. The internal batteries are auto-
matically disconnected when an AC Power Adaptor is used.
DC IN 10-12V
PA-5,
PA-5B,
or
PA-5C
AC power socket
• Never interrupt the power
supply (e.g. remove the batteries or unplug the AC adaptor)
during any PSR-320/420 record
operation! Doing so can result
in a loss of data.
• Use ONLY a Yamaha PA-5, PA-
5B, or PA-5C AC Power Adaptor 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-320/420.
■ Using Batteries...............................................................................................................................................
For battery operation the PSR-320/420 requires six 1.5V SUM-1, “D”
size, R-20 or equivalent batteries.
When the batteries need to be replaced “Btry Low” will appear on the
display. Also the volume may be reduced, the sound may be distorted, and
other problems may occur . When this happens, turn the power off and either
replace the batteries or connect an AC adaptor.
Replace the batteries as follows:
ZOpen the battery compartment cover located on the instrument’s bottom
panel.
XInsert the six new batteries, being careful to follow the polarity markings
on the inside of the compartment.
CReplace the compartment cover, making sure that it locks firmly in place.
• When the batteries run down,
replace them with a complete
set of six new batteries.
NEVER mix old and new batteries.
• Do not use different kinds of
batteries (e.g. alkaline and
manganese) at the same time.
• To prevent possible damage
due to battery leakage, remove
the batteries from the instrument if it is not to be used for
an extended period of time.
■ The PHONES Jack...................................................................................................................................
A standard pair of stereo headphones can be plugged in here for private
practice or late-night playing. The internal stereo speaker system is automatically shut off when a pair of headphones is plugged into the PHONES
jack.
An optional Yamaha FC4 or FC5 footswitch can be plugged into the rear-
panel SUSTAIN jack for sustain control. The footswitch functions like the
damper pedal on a piano — press for sustain, release for normal sound.
Setting Up
• The PHONES jack can also be
used to deliver the output of the
PSR-320/420 to a keyboard
amplifier, stereo sound system,
mixing console or tape recorder.
• Be sure that you do not press the
pedal while turning the power on.
If you do, the ON/OFF status of
the footswitch will be reversed.
SUSTAIN
■ MIDI IN and OUT Connectors.............................................................................................
The MIDI IN connector receives MIDI data from an external MIDI de-
vice (such as a MIDI sequencer) which can be used to control the PSR-320/
420. The MIDI OUT connector transmits MIDI data generated by the PSR320/420 (e.g. note and velocity data produced by playing the keyboard).
More details on MIDI are provided on page 56.
MIDI
OUTIN
The Music Stand
The PSR-320/420 is supplied with a music stand that can be attached to the instrument by inserting it into the slot at the rear
of the control panel.
Once you’ve set up your PSR-320/420, try listening to the pre-programmed demonstration songs — they’ll give you a good idea of what
the PSR-320/420 can do! A total of 16 demo songs are provided —
songs 01 through 08 have been created to demonstrate several of the
instrument’s voices , while songs 09 through 16 demonstrate a range of
accompaniment styles.
Set an Initial Volume Level.......................................................................................................

Turn the [MASTER VOLUME] control up (clockwise) about a quarterturn from its minimum position. You can re-adjust the [MASTER VOL-UME] control for the most comfortable overall volume level after playback
begins.
Press the [DEMO] Button...........................................................................................................

Press the [DEMO] button to start demo playback. The PSR-320/420
SONG mode will automatically be selected and the number and name of the
