After selecting this instrument from the connection list on your Bluetooth-equipped device, the pairing is completed.

Make sure to complete this operation while the instrument’s power lamp is flashing (within five minutes).

3. Play back audio data on the Bluetooth-equipped device to confirm that the instrument

can output the audio sound.

Disconnecting the current Bluetooth connection is done by turning off the Bluetooth function on the Bluetooth-equipped

device or disconnecting the instrument from the Bluetooth-equipped device.

When you turn on the instrument the next time, the last-connected Bluetooth-equipped device will be connected to this

instrument automatically, if the Bluetooth function of the Bluetooth-equipped device is set to on. To disable auto

connection of Bluetooth-equipped device to the instrument, delete the pairing information from the Bluetooth-equipped

device.

IMPORTANT

Even while playing audio playback from a Bluetooth-equipped device through the instrument, the instrument will

automatically turn off if it is not operated for 15 minutes, due to the Auto Power Off function. If desired, disable the Auto

Power Off function, see page 9.

• This instrument cannot transmit audio data to Bluetooth-equipped devices via Bluetooth.

• Bluetooth headphones or Bluetooth speakers cannot be connected or used with this instrument.

• Smart device apps such as Smart Pianist cannot be used via the Bluetooth Audio function described here.

NOTE

Flashes

Pairing

P-145BT, P-143BT Owner’s Manual

If you cannot pair or connect your Bluetooth-equipped device to the instrument:

• Check that the Bluetooth function of the Bluetooth-equipped device is activated and select this instrument again from

the connection list on your device.

• The device you are trying to connect to the instrument may be connected via Bluetooth to a device other than this

instrument. Disconnect from the currently connected device.

• If the instrument is already paired with multiple devices, it may automatically be connected to an unintended device. If

this occurs, disconnect the nearby device unintended for Bluetooth connection from the instrument, and then select this

instrument from the connection list on your device. Alternatively, begin the pairing process again.

• In case there is a device (microwave oven, wireless LAN device, etc.) that outputs signals in the 2.4 GHz frequency

band nearby, move this instrument away from the device that is emitting radio-frequency signals.

About Bluetooth

Bluetooth is a technology for wireless communication between devices within an area of about 10 meters (33 ft.)

employing the 2.4 GHz frequency band.

 Handling Bluetooth communications

• The 2.4 GHz band used by Bluetooth compatible devices is a radio band shared by many types of equipment.

While Bluetooth compatible devices use a technology minimizing the influence of other components using the

same radio band, such influence may reduce the speed or distance of communications and in some cases

interrupt communications.

• The speed of signal transfer and the distance at which communication is possible differs according to the distance

between the communicating devices, the presence of obstacles, radio wave conditions and the type of equipment.

• Yamaha does not guarantee all wireless connections between this unit and devices compatible with Bluetooth

function.

Troubleshooting

Problem Possible Cause and Solution

The instrument does not turn on.

The instrument has not been plugged in properly. Securely insert the female plug into

the jack on the instrument, and the male plug into a proper AC outlet (page 9).

The instrument is automatically turned off even if

no operation is done.

This is normal and due to the Auto Power Off function. Even if audio is being played

back from a smart device or another device connected to the instrument via USB cable

or Bluetooth, the instrument will automatically turn off if it is not operated. If you want to

prevent this from happening, disable the Auto Power Off function (page 9).

Noise is heard from the speakers or

headphones.

The noise may be due to interference caused by the use of a mobile phone in close

proximity to this instrument. Turn off the mobile phone, or move it further away from this

instrument.

When you use the instrument along with the application on your smart device, we

recommend that you set “Airplane Mode” to “ON” on your smart device in order to avoid

noise caused by communication.

The overall volume is low, or no sound is heard.

The Master Volume is set too low. Set it to an appropriate level using the [VOLUME]

slider (page 8).

Make sure a pair of headphones or conversion adaptor is not connected to the

[PHONES] jack (page 8).

The pedal has no effect.

The pedal cable/plug may not be properly connected. Turn off the power and make sure

to securely insert the pedal plug into the [SUSTAIN] jack or [PEDAL UNIT] jack (page 9,

17).

The footswitch (for sustain) seems to produce

the opposite effect. For example, pressing the

footswitch cuts off the sound and releasing it

sustains the sounds.

The polarity of the footswitch is reversed because the footswitch was pressed when the

power was turned on. Turn off the power and turn it on again to reset the function. Make

sure to not press the footswitch when turning the power on.

When connecting the computer or smart device

to the instrument’s [USB TO HOST] jack with a

USB cable and playing back audio data, no

sound comes out from the instrument or noise

occurs.

Depending on the model or OS of the computer and smart device, communication may

not be possible.

Backup and Initialization

The following backup parameters will automatically be maintained even if you turn off the power.

Backup parameters

Metronome Volume, Metronome Beat, Touch Sensitivity, Tuning, Auto Power Off, Operation Confirmation Sound on/

off, Bluetooth pairing information

To initialize the backup parameters:

While holding down the C7 key (highest key), turn the power on to initialize the backup data to the factory initial

settings.

NOTICE

• Tempo settings are not backed up.

NOTE

Highest key

• Never turn off the power while the initialization is being

executed.

• If this instrument somehow malfunctions or fails to operate properly, try

executing the initialization.

• Bluetooth pairing information (page 12) will not be lost even when the

initializing is executed.

Damper pedal (right pedal)

Notes will be sustained as long as this pedal is depressed, even if you release your fingers from the keys. It corresponds to the Damper

Resonance function. The deeper you depress the pedal, the longer the note is sustained (corresponding to the Half Pedal function).

Sostenuto pedal (center pedal)

If you play a note or chord on the keyboard and press the sostenuto pedal while

holding the note(s), the notes will sustain as long as the pedal is held. Since this

pedal does not affect notes played while it is depressed, you can achieve playing

styles such as a staccato melody while sustaining a chord.

Soft pedal (left pedal)

Keys played after depressing this pedal will be slightly softer and less resonant. The effect continues as long as the pedal is depressed.

Since this pedal does not affect the sound of keys that were already held down when it is depressed, depress the pedal just before

playing the note(s) that you would like to alter.

Half-pedal function

This function allows you to vary the sustain length

depending on how far the Damper 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 or

higher to decrease the sustain (murkiness).

Pedal Functions (For Pedal Unit LP-5A)

When you press the sostenuto pedal here while holding the

note(s), the notes will sustain as long as you hold the pedal.

• Right Pedal: Damper pedal for the right-hand range.
