Solution

Securely insert the female plug into the socket on the P-250, and the male plug into a proper AC outlet. (page 16) This is normal. Turn off the mobile phone, or use it further away from the P-250. Using a mobile phone in close proximity to the P-250 may produce interference. Raise the [MASTER VOLUME] level. Disconnect the headphone plug.
A click or pop is heard when the power is turned on or off. Noise is heard from the P-250 speakers. The overall volume is too low, or there is no sound at all.
Set Speaker to Normal or ON. (page 79) Turn the Local Control function on. Set the InternalTG to on. Assign any function other than Expression to the pedal. Raise the Master EQ gain level. Raise the Part EQ gain level. Move the [SONG BALANCE] slider toward KEYBOARD to increase the keyboard volume. Set Speaker to Normal. (page 79)
The keyboard volume is lower than the song playback volume. The speakers do not turn off when a pair of headphones is connected. The buttons do not respond.
The volume level for the keyboard performance is set too low. The speaker setting is on.
While you are using a function, some buttons not used for the function are disabled. With the voices in the ORGAN1, ORGAN2, STRINGS, CHOIR, or SYNTH.PAD group, or part of the XG group, the sound continues sustaining while you hold down the sostenuto pedal. The setting range for the transposition and octave setting is C-2 - G8. (With the normal setting, the units 88 keys cover the range of A-1 - C7.) If the lowest key is set to a note lower than C-2, it will produce a sound one octave higher. If the highest key is set to a note higher than G8, it will produce a sound one octave lower. Depending on the timing of the tempo changes, the changed tempo may not be recorded. In this case, the recording will be played back at the original tempo. Make tempo changes when the recording track is selected and the red track indicator is ashing. The same trick applies to editing the tempo after recording.
If a song is recording or playing, stop recording or playback. Otherwise, press the [EXIT] button to return to the main screen. Then, perform the desired operation. This is normal.

See next page for details about Open Plug-in Technology.
4 TOOLS for P-250 Installation Guide
You can start the File Utility software as either a stand-alone software or a plug-in application in the Open Plug-in Technology compatible application. Refer to the owner's manual of the client application (sequencer, etc.) for details on using the File Utility as a plug-in software.
About Open Plug-in Technology
Open Plug-in Technology (OPT) is a newly developed software format that allows control over MIDI devices from a music software sequencer. For example, this allows you to start up and operate various parts of your music system, such as plug-in board editors, and mixing control editors - directly from an OPT-compatible sequencer, without having to use each separately. This also makes it unnecessary to set MIDI drivers for each application, streamlining your music production system and making all operations more convenient and seamless. About the OPT Levels The client application and its compatibility with OPT can be divided into three levels, as shown below. Level 1 OPT Panels provides basic support for opening and displaying OPT control panels that can transmit data via the clients external MIDI ports. Typically this will allow basic hardware editor control panels to operate properly. Level 2 OPT Processors provides support for real-time MIDI processors and panel automation. Typically this will allow both real-time and offline MIDI effects (e.g. Arpeggiators, transposers etc.) to operate properly and supply automation to OPT panels. Level 3 OPT Views provides support for edit views and MIDI processors/panels that require direct access to client sequencer storage structures. Typically this will allow sophisticated MIDI edit views to be supported (e.g. List editors, Auto Accompaniment, Data Checkers etc.).
