IMPORTANT NOTICE
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: 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 per form 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.
IMPORTANT: This presentation or sale of this manual to any individual or firm does not constitute authorization, certifica-
tion, recognition of any applicable technical capabilities, or establish a principal-agent relationship of any
form.
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, therefor, 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: Static discharges can destroy expensive components. Discharge any static electricity you body may have
accumulated by grounding yourself to the ground buss in the unit (heavy gauge black wires connect to this
buss).
IMPORTANT: Turn the unit OFF during disassembly and parts replacement. Recheck all work before you apply power to
the unit.
WARNING: CHEMICAL CONTENT NOTICE!

The solder used in the production of this product contains LEAD. In addition, other electrical / electronic and / or plastic (where
applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly
other entities) to cause cancer and / 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!
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.
LUTHIUM BATTERY HANDLING

This product uses a lithium battery for memory back-up.
WARNING: Lithium batteries are dangerous because they can be exploded by improper handling. Observe the follow-
ing precautions when handling or replacing lithium batteries.
● Leave lithium battery replacement to qualified service personnel.
● Always replace with batteries of the same type.
● When installing on the PC board by soldering, solder using the connection terminals provided on the battery cells.
Never solder directly to the cells. perform the soldering as quickly as possible.
● Never reverse the battery polarities when installing.
● Do not short the batteries.
● Do not attempt to recharge these batteries.
● Do not disassemble the batteries.
● Never heat batteries or throw them into fire.
ADVARSEL!
Lithiumbatteri—Eksplosionsfare ved fejlagtig håndtering. Udskiftning må kun ske med batteri af samme fabrikat og type. Levér
det brugte batteri tilbage til leverandoren.
VARNING
Explosionsfara vid felaktigt batteribyte. Använd samma batterityp eller en ekvivalent typ som rekommenderas av
apparattillverkaren. Kassera använt batteri enlight fabrikantens instruktion.
VAROITUS
Paristo voi räjähtää, jos se on virheellisesti asennettu. Vaihda paristo ainoastaan laitevalmistajan suosittelemaan tyyppiin. Hävitä
käytetty paristo valmistajan ohjeiden mukaisesti.
The following information complies with Dutch Official Gazette 1995. 45; ESSENTIALS OF ORDER ON THE COLLECTION OF
BATTERIES.
・Please refer to the diassembly procedure for the removal of Back-up Battery.
・Leest u voor het verwijderen van de backup batterij deze beschrijving.
WARNING
Components having special characteristics are marked and must be replaced with parts having specification equal to those originally
installed.

making the job invalid. Re-select the area.
Illegal Input This will appear in response to inappropriate operation or input. Check your input
method.
Illegal Track Number An unavailable or otherwise improper track number has been specified. Select a
different track.
Illegal Phrase Number An unavailable or otherwise improper phrase number has been specified. Select a
different phrase.
Illegal Measure An unavailable or otherwise improper measure number has been specified. Select a
different measure number.
Illegal Check Box This message will appear if no check boxes are checked in any of the corresponding
track jobs. At least one check box must be checked.
No F7 (End of Exc.) This message indicates that no “End of Exclusive” byte (F7) was included with a MIDI
exclusive data entry or edit. Be sure to include F7.
Preset Phrase This will appear when you attempt to edit a Preset Phrase. If you wish to edit a preset
phrase, you must first copy it to a User Phrase.
Preset Pattern This will appear when you attempt to record to a Preset Pattern. You cannot record to
Preset Patterns.
Pattern Length Mismatch A job has resulted in a pattern having more than the maximum of 256 measures.
Phrase Number Overflow All available user phrases (256 maximum) have been used up when recording,
executing a job, or editing.
● System
Backup Battery Low This will appear when the internal backup battery of the RM1x has run down. Replace the
battery to a new one.
Memory Full This will appear when internal memory is full and it is not possible to record, edit, execute
a job, receive MIDI, or load from floppy disk. Delete unneeded songs, patterns, or user
phrases, and try the operation once again.
Factory Set After the power is switched ON, a system diagnosis is run on the RM1x’s system. If the
diagnosis finds the RAM to be defective, this message will appear and the memory will be
reset to its original factory settings. Data for User Song, User Patterns, and User Phrases
will all be eliminated.
Memory Protect You have attempted to execute a recording, editing, or job function when the UTILITY
mode Memory Protect function is ON.
● MIDI
Exc. Adrs Error This appears when the received Exclusive data contains an address error.
Exc. Data Error This appears when the received Exclusive data contains a data size error.
MIDI Buffer Full This will appear when the MIDI reception buffer of the RM1x has filled up, and
processing is not possible. Try decreasing the amount of data or increasing the
interval time and transmit the data once again.

● Disk
Disk Full This will appear if the floppy disk is full and has no room to save the file. Either use a
new floppy disk, or delete unneeded files before trying the operation once again.
File Not Found When loading, this will appear if the specified file does not exist in the floppy disk.
Insert the disk once again, and try the operation again.
Bad Disk Format Now? The floppy disk is faulty. Press the [Yes +1] button to format the disk.
(Y/N)
No Disk This indicates that the floppy disk is not correctly inserted into the RM1x. Insert the
floppy disk correctly.
Unformat Format Now? This will appear if the floppy disk is not formatted. Press the [Yes +1] button to format
(Y/N) the disk.
Write Protected This will appear if the write-protect slider of the floppy disk is in the write prohibit
position. Remove the floppy disk, close the write-protect slider, and try the operation
once again.
Bad File This will appear when you attempt to load a defective file.
Illegal Format This will appear if the floppy disk is of a format which the RM1x is not able to handle.
Check the contents of the disk.
Disk Changed This will appear if you have exchanged disks when you should not have. Try the
operation once again from the beginning.
Can’t Change File Name When renaming, this will appear if the floppy disk already contains a file with a name
identical to the specified filename. Specify a different filename.
Illegal File When loading, this will appear if the specified file cannot be handled by the RM1x.
Check the contents of the file.
No Data When saving data to floppy disk, this will appear if the selected song or style contains
no data, and the save operation is invalid. Select a different song or style.
● Messages other than error messages

Can’t Undo. Ok? (Y/N) If executing a job would fill up the internal memory so that Undo will not be available,
this message will appear. If you are sure that you will not need to Undo this job,
press the [YES +1] button. To cancel without executing the job, press the [NO -1]
button, and delete unneeded songs, patterns, or user phrases before trying the
