This manual has been provided for the use of authorized Yamaha Retailers and their service personnel. It has been assumed that
basic service procedures inherent to the industry, and more specifically Yamaha Products, are already known and understood by the
users, and have therefore not been restated.

WARNING:

IMPORTANT:

The data provided is believed to be accurate and applicable to the unit(s) indicated on the cover. The research engineering, and
service departments of Yamaha are continually striving to improve Yamaha products. Modifications are, therefore, inevitable
and changes in specification are subject to change without notice or obligation to retrofit. Should any discrepancy appear to
exist, please contact the distributor's Service Division.

WARNING:

IMPORTANT:

WARNING: This product contains chemicals known to the State of California to cause cancer, or birth defects or other

reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON
WHAT SO EVER!

IMPORTANT NOTICE

Failure to follow appropriate service and safety procedures when servicing this product may result in per­sonal injury, destruction of expensive components and failure of the product to perform as specified. For
these reasons, we advise all Yamaha product owners that all service required should be performed by an
authorized Yamaha Retailer or the appointed service representative.

This presentation or sale of this manual to any individual or firm does not constitute authorization certifi­cation, recognition of any applicable technical capabilities, or establish a principal-agent relationship of
any form.

Static discharges can destroy expensive components. Discharge any static electricity your body may have
accumulated by grounding yourself to the ground bus in the unit (heavy gauge black wires connect to
this bus.)

Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to
the unit.

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose
eyes to solder/ flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands before
handling food.

WARNING

Components having special characteristics are marked and must be replaced with parts having specification equal to those
originally installed.

SAVING DATA

Saving and backing up your data

The panel settings and some other types of data are not retained in memory when you turn off the power to the
instrument. Save data you want to keep to the Registration Memory.
Saved data may be lost due to malfunction or incorrect operation.

Be sure to

erform it

Backing up the USB storage device/external media

Be sure to

erform it

Save important data to a USB storage device/or other external device such as a computer.

To protect against data loss through media damage, we recommend that you save your important data onto two
USB storage devices/external media.

■ TEST PROGRAM

* If you execute the test No.49 (Factory Set), then the user's preset data may be lost.

Therefore, back up the user's data in advance.

A. PREPARATION

1) PA-301 or PA-300B (AC adaptor) is used.

2) Measuring instruments: frequency counter, level meter (with JIS-C filter)

Note: Connect a stereo plug to the [PHONES/OUTPUT] jack at 33 Ω.

3) Jigs: Foot switch (FC-4 or FC-5), USB cable, USB flash memory, USB-MIDI driver (*1)

PC (Install a USB-MIDI driver (*1) in PC and finish the THROUGH setup.)

*1 Obtain the USB-MIDI driver from CD-ROM(X9448A00) for PSR-S550/PSR-S550B or Yamaha official website.

(URL>>http://www.yamahapkclub.com)

B. HOW TO ENTER THE TEST PROGRAM

While pressing the C2#, F2 and G2# keys, turn the [STANDBY/ON] switch on.

keys simultaneously, the first pressed key has priority to make a sound.)

Check that the correct signal is produced. (441.0 Hz ± 0.2 Hz)

-- Volume Decrescence Check

Connect the level meter(with a JIS-C filter) to the [PHONES/OUTPUT] jack. (33Ω load)

Set the [MASTER VOLUME] at minimum and check the output level.

PHONES L : less than -70.0 dBu PHONES R : -70.0 dBu (dBu=dBm)

Connect the level meter (with a JIS-C filter) to the [PHONES/OUTPUT] jack. (33Ω load)

Set the [MASTER VOLUME] at maximum and check the output level (1 kHz sine

wave, PAN=R).

PHONES L : less than -45.0 dBu PHONES R : -5.5 dBu ± 2 dB

Connect the level meter (with a JIS-C filter) to the [PHONES/OUTPUT] jack. (33Ω load)

Set the [MASTER VOLUME] at maximum and check the output level (1 kHz sine

wave, PAN=L).

PHONES L : -5.5 dBu ± 2 dB PHONES R : less than -45.0 dBu

Press the switches on the LCD as instructed. A pre-assigned note is output when the

switch is pressed. A rotary encoder is clockwise set up to UP and is counterclockwise

set to DOWN. (See P.36 "Table 1".)

The check result appears on the LCD when all the switches are pressed as instructed.
