Turning the Power On
1	Connect the power cord.
First insert the plug of the power cable into the [AC IN] jack on your instrument, then plug the other end of the cable into the proper AC outlet on the wall. For an illustration of the location of the [AC IN] jack, see gPanel Controls and Terminalsh (page 8). In some areas a plug adaptor may be provided to match the pin configuration of the AC wall outlets in your area.


(Figure)
The shape of the plug differs depending on the locale.


WARNING
- Make sure your instrument is rated for the AC voltage supplied in the area in which it is to be used (voltage rating appears on the name plate on the bottom panel). In some areas, a voltage selector may be provided on the bottom panel of the main keyboard unit near the [AC IN] jack. Make sure that the voltage selector is set for the voltage in your area. Connecting the unit to the wrong AC supply can cause serious damage to the internal circuitry and may even pose a shock hazard!
- Use only the AC power cord supplied with your instrument. If the supplied cord is lost or damaged and needs to be replaced, contact your Yamaha dealer. The use of an inappropriate replacement can pose a fire and shock hazard!
- The type of AC power cord provided with your instrument may be different depending on the country in which it is purchased.
Do NOT modify the plug provided with your instrument. If the plug does not fit the outlet, have a proper outlet installed by a qualified electrician.

2	Press the [POWER] power switch to turn the power on.

[POWER]


Power indicator
If you close the key cover without turning the power off, the power indicator remains lit, indicating that the power is still on.

When you're ready to turn off the power, press the power switch again. The power indicator turns off.

CAUTION
Even when the instrument is turned off, electricity is still flowing to the instrument at the minimum level. When you are not using the instrument for a long time or during electrical storms, make sure you unplug the AC power plug from the wall AC outlet.





Using Headphones
Since this instrument is equipped with two [PHONES] jacks, you can connect two sets of standard stereo headphones. If you are using only one set of headphones, insert a plug into either jack, which automatically shuts off the speakers.


(Figure)
Bottom surface
Standard stereo phone plug


CAUTION
Do not use headphones at a high volume for an extended period of time;
doing so may cause hearing loss.

Using the headphone hanger
You can hang the headphones on the instrument. Install the headphone hanger using included two screws as shown in the illustration.

NOTICE
Do not hang anything other than the headphones on the hanger. Doing so may damage this instrument or the hanger.






Playing the Piano

Setting the Volume
When you start playing, use the [MASTER VOLUME] knob to adjust the volume of the entire keyboard sound.


(Figure)
Level decreases.
Level increases.


CAUTION
Do not use this instrument at a high volume level for a long period of time, or your hearing may be damaged.





Using the Pedals
Damper Pedal (Right)
Pressing this pedal will sustain notes longer. Releasing this pedal immediately stops (damps) any sustained notes. A ghalf-pedalh function of this pedal creates partial sustain effects, depending on how far down you press the pedal.


(Figure)
When you press the damper pedal here, this note and the notes you play before you release the pedal sustain longer.


NOTE
If the damper pedal doesn't work, make sure that the pedal cord is properly plugged into the main unit (page 30).

Half-pedal function
This function allows you to vary the sustain length depending on how far the pedal is pressed. 
The farther down you press the pedal, the more the sound sustains. For example, if you press the damper pedal and all notes you are playing sound a bit murky and loud with too much sustain, you can release the pedal half way to decrease the sustain (murkiness)


Sostenuto Pedal (Center)
Pressing this pedal while holding the notes will sustain the pressed notes (as if the Damper Pedal had been pressed), but all subsequently played notes will not be sustained. This makes it possible to sustain a chord, for example, while the other notes are played gstaccato.h


(Figure)
When you press the sostenuto pedal here while holding the note, the note will sustain as long as you hold the pedal.


NOTE
While the sostenuto pedal is held, the organ and strings Voices sound continuously without decay after the notes have been released.


Soft Pedal (Left)
Pressing this pedal will reduce the volume and slightly change the timbre of the notes. 
The notes played before this pedal is pressed are not affected.





Using the Damper Resonance
When playing an actual grand piano, the strings resonate sympathetically, whether the damper pedal is pressed or not. The Damper Resonance function recreates that effect.

To turn on the Damper Resonance: 
While holding [PIANO/VOICE], press the G#2 key.

To turn off the Damper Resonance:
While holding [PIANO/VOICE], press the G2 key.

Default setting: On

Maintenance

To keep your ARIUS in optimum condition, we recommend that you periodically follow the maintenance points below.

Instrument and Bench Maintenance
- When cleaning the instrument, use a soft, dry or slightly damp cloth.

NOTICE
Do not use paint thinners, solvents, cleaning fluids, or chemical-impregnated wiping cloths.

Gently remove dust and dirt with a soft cloth. Do not wipe too hard since small particles of dirt can scratch the instrument's finish.
To keep the surface polished, apply commercially available piano polisher to a soft cloth and wipe the instrument's surface with it. Then, polish it with a separate cloth. Before using any piano polisher, make sure to read the instructions for proper usage.

- Tighten the screws of the instrument and bench periodically.

Pedal Cleaning
As with an acoustic piano, pedals may become tarnished over years of use. When this occurs, polish the pedal with a compound designed for piano pedals. Before using the compound, make sure to read the instructions for proper usage.

Tuning
Unlike an acoustic piano, this instrument does not need to be tuned by an expert (although the pitch can be user-adjusted to match other instruments). This is because the pitch of digital instruments is always maintained perfectly. However, if you feel there is something abnormal concerning the keyboard touch, contact your Yamaha dealer.

When transporting
You can load this instrument onto a truck, either fully assembled or disassembled. When doing so, do not lean the instrument (especially the keyboard unit) against a wall, and make sure to lay it horizontally in the truck. When transporting by truck, do not subject the instrument to excessive vibration or shock. If you transport the instrument fully assembled, make sure to check all the
screws then tighten them as necessary.

Using the MIDI terminals

What's MIDI ?
MIDI is an acronym that stands for Musical Instrument Digital Interface, a technology that allows electronic musical instruments to communicate with each other, by sending and receiving performance information.
Connecting MIDI-compatible musical instruments via MIDI cables enables you transfer the performance and setting data -MIDI data- between multiple musical instruments. Using MIDI, you can also achieve more advanced performances than using just a single musical instrument.

(Figure)

NOTE
MIDI data that can be handled varies depending on the instrument. For details, see the MIDI Implementation Chart in the gMIDI Reference.h

NOTE
You need a dedicated MIDI cable (optional) to make a MIDI connection. You can purchase MIDI cables at musical instrument stores.





What You Can Do With MIDI
Controlling another keyboard, and vice versa
When making the connections shown below, you can play one of the keyboards and control the tone generator of the other instrument.

To set the Receive Channel:
While holding down [DEMO/SONG] and [PIANO/VOICE] simultaneously, press one of the C4-F5 keys.

NOTE
Default settings:
- Transmit Channel
Voice 1: Ch1
- Receive Channel
All (Ch1 - Ch16; all channels)

About the value
- When the Transmit Channel is set to off, no MIDI data is transmitted even if you play the keyboard.
- When the Receive Channel is set to all, this instrument receives MIDI data over all channels, such as with multi-channel SMF data.
- When the Receive Channel is set to 1+2, this instrument receives MIDI data over channels 1 and 2, such as with Piano Song data.

Transmit Channel in Dual
While the Voice 1 Part is transmitted over the specified Channel, the Voice 2 Part is transmitted over the next highest Channel.
