Preparing the Music Stand

Preparing a Power Supply

Your Digital Piano uses an AC adaptor for power.

Note:
Though this Digital Piano supports battery operation, use of an AC adaptor is generally recommended.

Using the AC Adaptor
Make sure that you use only the AC adaptor specified for this Digital Piano. Use of a different type AC adaptor can cause smoking or malfunction.

Specified AC Adaptor: AD-A12150LW (JEITA Standard plug)

Important:

• Never connect the AC adaptor (JEITA Standard, with unified polarity plug) that comes with this Digital Piano to any other device besides this Digital Piano. Doing so creates the risk of malfunction.

• Be sure to turn off Digital Piano power before connecting or disconnecting the AC adaptor.

• The AC adaptor will become warm to the touch after very long use. This is normal and does not indicate malfunction.

• Note the important precautions below to avoid damage to the power cord.
  During Use

  • Never pull on the cord with excessive force.

  • Never repeatedly pull on the cord.

  • Never twist the cord at the base of the plug or connector.
    During Movement

  • Before moving the Digital Piano, be sure to unplug the AC adaptor from the power outlet.
    During Storage

  • Loop and bundle the power cord, but never wind it around the AC adaptor.

• Never insert metal, pencils, or any other objects into the product’s DC12V terminal. Doing so creates the risk of accident.

• Do not try to use the power cord that comes with the product with another device.

• Plug the AC adaptor into a power outlet that is close to the Digital Piano. This lets you immediately unplug from the power outlet should any problem occur.

• The AC adaptor is intended for indoor use only. Do not leave it in a location where it can become wet. Also, do not place a vase or any other container of liquid on the AC adaptor.

• Make sure that the AC adaptor does not become covered with a newspaper, tablecloth, curtain, or any other type of fabric.

• If you do not plan to use the Digital Piano for a long time, unplug the AC adaptor from the power outlet.

• The AC adaptor cannot be repaired. If your AC adaptor malfunctions or becomes damaged, you need to purchase a new one.

• AC Adaptor Usage Environment

  • Temperature: 0 to 40°C
  • Humidity: 10% to 90%RH
  • Output Polarity:

Using Batteries

Important:

• Be sure to turn off the power before loading the batteries.
• It is up to you to prepare six commercially available alkaline batteries.
• Note the precautions below while the Digital Piano is turned upside down to load batteries.
  • Take care to avoid injury due to pinching your fingers under the Digital Piano.
  • Do not allow the Digital Piano to tip over or otherwise be subjected to strong impact. The impact can damage the volume knob and keyboard keys.

1. Open the battery cover on the bottom of the Digital Piano.

2. Load six AA-size batteries into the battery compartment.
   Make sure the positive + and negative – ends of the batteries are facing as marked on the Digital Piano.

3. Insert the tabs of the battery cover into the holes along the side of the battery compartment, and close the cover.

Low Battery Indication
Low batteries are indicated by the 1 (Power) button lamp flashing. When this happens, replace the batteries.

Important:
Using the Digital Piano while batteries are very low can cause it to turn off suddenly. This can cause data stored in Digital Piano memory to be corrupted or lost.

Turning Power On or Off

1. Press the 1 (Power) button to turn on Digital Piano power.
   • The power lamp lights and the Digital Piano powers up. The power-up operation takes a few seconds.
   • Use 2 VOLUME to adjust volume.
2. To turn off the Digital Piano, hold down the 1 (Power) button until the power lamp goes out.

NOTE:

• Pressing the 1 (Power) button to turn off power actually puts the Digital Piano into a standby state. Minute amounts of current continue to flow within the Digital Piano in the standby state. If you do not plan to use the Digital Piano for a long time or if there is a lightning storm in your area, be sure to unplug the AC adaptor from the power outlet.
• Turning off power causes the Digital Piano settings to return to their initial defaults. The tuning setting, however, is retained.

Auto Power Off
This Digital Piano is designed to turn off automatically to avoid wasting power after no operation is performed for a preset amount of time. The Auto Power Off trigger time is about four hours when power is being supplied by the AC adaptor or six minutes under battery power.

• You can use the procedure below to enable or disable Auto Power Off.

To enable or disable Auto Power Off

1. While holding down 3 FUNCTIONS, press the B6 (Auto Power Off) keyboard key.
   • Each press of the B6 keyboard key causes a short beep to sound. A low beep sounds when Auto Power Off is disabled, and a high beep sounds when it is enabled.
2. After the setting is the way you want, release 3 FUNCTION.

Returning the Digital Piano to Its Factory Default Settings

Perform the procedure below when you want to return the Digital Piano’s stored data and settings to their initial factory defaults.

1. While holding down 3 FUNCTION, perform steps (1) and (2) below.
2. Press the E7 (Factory Reset) keyboard key.

  * This will cause a short beep to sound.
  * Performing step (2) below will initialize the Digital Piano and return it to its factory default settings. If you want to cancel initialization at this point, release 3 FUNCTION.
2.  **Press the G7 (Execute) keyboard key.**
  * This causes a short and then long beep to sound, indicating that the operation is complete and that initialization has started.
  * The initialization takes some time to complete.
  * After settings are returned to their initial factory defaults, Digital Piano power will turn off automatically.

2. Release 3 FUNCTION.

Connecting a Pedal

• Connecting the supplied pedal (SP-3) to the 6 DAMPER PEDAL jack makes it possible to use the pedal as a damper pedal.
• Pressing the damper pedal while playing will cause the notes you play to reverberate.

6 DAMPER PEDAL jack (Standard jack (6.3mm))

Using Headphones

Using headphones cuts off output from the built-in speakers, which means you can practice playing even late at night without disturbing others.

• Be sure to turn down the volume level before connecting headphones.

NOTE:

• Headphones do not come with the Digital Piano.
• Use commercially available headphones.

Important:

• Do not listen to very high volume output over headphones for long period. Doing so creates the risk of hearing damage.

4. Release 3 FUNCTION.

Fine Tuning a Pitch (Tuning)

• The tuning feature specifies the frequency of the A4 note. You can set a frequency within the range of 415.5 to 465.9 Hz. The initial default setting is 440.0 Hz.
• The setting you configure is retained even if you turn off the Digital Piano.

To change the tuning setting

1. While holding down 3 FUNCTION, perform steps (1) through (3) below.
   Note:

2. If a key operation during steps (1) through (3) would cause the setting to exceed its upper or lower maximum limit, a high and then low beep will sound to indicate that the setting cannot be changed further.

3. Press the TUNE– keyboard key (G5) or the TUNE+ keyboard key (A}5).

    * Pressing the TUNE– key (G5) will lower the current pitch setting by 0.1 Hz while pressing TUNE+ (A}5) will raise it by 0.1 Hz.
    * If you just want to fine-tune the current pitch setting, go directly to step (3) below.
  2. To input a pitch value, use the [0] (E4) through [9](C{5) keyboard keys to input an integer that specifies the frequency (Hz) of the A4 note.
    * For example, to specify a frequency of 442 Hz, press keyboard keys in the following sequence: [4] (A}4) 3 [4] (A}4) 3 [2] (F{4). Inputting the third and final digit will cause a short and then long beep to sound, indicating that the value you input was applied.
    * You can specify a value in the range of 416 through 465 Hz.
  3. To fine-tune by 0.1 Hz increments, press the TUNE–keyboard key (G5) to lower the pitch by 0.1 Hz or the TUNE+ keyboard key (A}5) to raise the pitch by 0.1 Hz.
    * Each press of the keyboard key causes a beep to sound. The beep becomes higher whenever a key operation causes the setting value to become an integer.
    * You can specify a value in the range of 415.5 through 465.9 Hz.
    * To return to the initial default setting, hold down the keyboard TUNE– (G5) and TUNE+ (A}5) keys at the same time until a long beep sounds.

2. Release 3 FUNCTION.

Changing the Beep Setting

You can use the 3 FUNCTION button operation below to toggle the beep tone between enabled and disabled.
