This document is posted to help you gain knowledge. Please leave a comment to let me know what you think about it! Share it to your friends and learn new things together.
WARNING: CHEMICAL CONTENT NOTICE!The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (whereapplicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possiblyother 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 REASONWHAT SO EVER!
Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyesto solder/flux vapor!
If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handlingfood.
LITHIUM BATTERY HANDLINGThis product uses a lithium battery for memory back-up.
WARNING: Lithium batteries are dangerous because they can be exploded by improper handling. Observe the followingprecautions 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 detbrugte batteri tilbage til leverandøren.
VARNINGExplosionsfara vid felaktigt batteribyte.Använd samma batterityp eller en ekvivalent typ som rekommenderas av apparattillverkaren.Kassera använt batteri enligt fabrikantens instruktion.
VAROITUSParisto 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 OFBATTERIES.
•Please refer to the diassembly procedure for the removal of Back-up Battery.•Leest u voor het verwijderen van de backup batterij deze beschrijving.

INITIALIZEThe Initialize feature lets you restore the initial factorydefault settings with a quick and simple operation.Before initializing the settings, make sure to first offloadany data that you want to save using the Bulk Dumpoperation. Otherwise, the Voice and Performance datayou have created will be lost permanently.
INITIALIZING THE DEFAULT SETTINGS
Press the [POWER] switch to turn off the power.
To initialize all the default settings, hold both the[MIDI] and [EDIT] buttons, then press the[POWER] switch to turn on the power.
The INITIALIZE ALL screen briefly appears.
PERFORMANCE A (or B) BANK: You can alsoinitialize only the Performance A bank (or Bbank) default settings. To do so, first turn thepower off, then hold both the [MIDI] and [PERF.A] (or [PERF. B]) buttons and turn the powerback on.
VOICE SETTINGS: Similarly, you can initializeonly the Voice parameter default settings. To doso, first turn the power off, then hold both the[MIDI] and [VOICE] buttons and turn the powerback on.

3.2.5 Pitch BendOnly the MSB of the Pitch Bend is received.
3.2.6 Channel ModeChannel Mode messages are received.
Channel Mode messages are received by the Receive channelwhile Omni Off is selected.
All Sounds Off —Reception is while Omni Off is selected only.While Omni Off is selected, reception only occurs on the sameReceive channel, and Key On sounds are quickly silenced.Different from All Notes Off, a dump is forcibly taken and sound issilenced even when a damper or Sostenuto causes the soundafter a Key Off to continue or reduce slowly.
All Notes Off —While Omni Off is selected, only those sounds that occur duringKey On in the Receive Channel are silenced. Nothing is donewhile Omni On is selected.
Reset All Controllers —While Omni Off is selected, only the Receive channel is reset toits initial value. Nothing is done while Omni On is selected.At reception, the status of the following items are reset to theirinitial values: Modulation Depth, Main Volume, Sustain, Soft, Sostenuto, andPitch Bend Depth. (Reverb Depth remains unchanged.)
Modulation Depth: Off Main Volume: MaxSustain: Off Soft: OffSostenuto: Off Pitch Bend Depth (Center)
4. SYSTEM REAL TIME MESSAGESWhen Start, Continue, or Stop is assigned to PS1/2 controller,System Realtime messages are transmitted.
The system is capable of sending and receiving the following typesof bulk dump messages:1. System Setup Bulk Dump2. Voice Bulk Dump3. Keyboard Mode Bulk Dump4. MIDI Filter Table Bulk Dump5. Program Change Transmit Table Bulk Dump6. Program Change Receive Table Bulk Dump
The following three types of bulk dumps are sent and received:1. All Bulk Dump
All six types of bulk dumps as listed above will be sent.2. Performance Bulk Dump
Types 2 and 3, listed above, will be sent, for Performance Playmode Performances A01 ~ A12 or B01 ~ 12.
3. Voice Bulk DumpTypes 2 and 3, listed above, will be sent, for Voice Play modeVoices 1 ~ 12 and currently stored panel settings.
The above six types of bulk dump messages can be receivedindependently.
For more information about bulk dump format, see page 85.You can assign the device number in Edit mode, System function;see page 51.When the device number is set to Off, bulk dump send andreceive operations cannot be executed.When MIDI Merge (Edit mode, System function) is set to On, theP-200 cannot send bulk dump messages.When the device numbers of the P-200 and the external deviceare not matched, the P-200 cannot receive bulk dump messages.Bulk dump messages cannot be sent and received at the same time.When the MIDI Filter bulk setting (Edit mode, MIDI Filter function)is set to On, bulk dump operations cannot be executed.
5.3 MIDI MERGEThe MIDI Merge function enables you to merge data received fromthe MIDI IN termimal with data generated by the P-200, andtransmits this merged data. This function works as follows:
1. Some features, such as Controller, might not operate as expectedbecause channel messages can also be transmitted on the samechannel as the MIDI channel that the P-200 uses for transmission.(For example, in the case of Controller, an external deviceconnected to MIDI OUT uses the value determined by the mostrecently used instrument, P-200 or an external device connectedto MIDI IN. The sounds from the P-200's tone generator mightsometimes cut off when receiving an All Notes Off message.)
2. A received Active Sensing message is never transmitted.3. When an interrupt of the received Active Sensing is detected, transmission
of Active Sensing through MIDI OUT is interrupted after 500msec.4. When the P-200 receives 32 or more bytes of System Exclusive
Messages, the MIDI messages transmitted by the P-200 mightcause an interruption. (When System Exclusive Messages from MIDI IN are received,the MIDI messages that the P-200 attempted to transmit areheld temporarily; however, if the data exceeds 31 bytes, the holdis released and after an EOX is forcibly transmitted, the P-200MIDI messages are transmitted. In this case the data bytes beingreceived are not transmitted until reception of the status byte ofnon-System Realtime Messages, and are discarded.)
5. When the MIDI Merge function is On, Bulk Dumps cannot be sentfrom the P-200.
6. After the P-200 receives one status byte of the System ExclusiveMessages, if the status of other channel messages, etc., arereceived before an EOX is received, the EOX is transmitted andother messages (for example, channel messages) are separatedfrom the System Exclusive Messages and are transmitted.
* When MIDI Merge is On, the MIDI Panic feature does not work.
5.4 MIDI PanicWith the P-200, pressing the [MIDI]+[REVERB]+[MODULATION]buttons suppresses MIDI transmission as an emergency method toshut down all sound.
MIDI transmissionThe following messages are transmitted : Modulation Depth Off, Sustain Pedal Off, All Sound Off, All NoteOff, Reset All Controllers, Pitch Bend Depth (Center) andChannel Pressure Off, for all channels.MIDI Panic transmission is not possible when the MIDI Mergefunction is On.MIDI Panic transmission is not possible during sending/receiving bulk data.
* The MIDI Panic feature is an emergency measure of last resort, sosound sometimes might not stop.
