TROUBLESHOOTING Problem When the PortaTone is turned on or off, a popping sound is temporarily produced. There is no sound even when the keyboard is played or when a song is being played back. The selected voice does not sound properly, or is too low in volume. There is no sound when playing the keyboard. Playing keys in the right hand section of the keyboard does not produce any sound. The sound of the voices or rhythms seems unusual or strange. The accompaniment does not play back even when pressing the START/STOP button. There is no sound on either the PortaTone or the connected MIDI device. The accompaniment does not sound properly. The Reverb/Chorus/DSP/Harmony cannot be heard properly. When playing back one of the Pianist styles (#91 - #100), the rhythm cannot be heard. Not all of the voices seem to sound, or the sound seems to be cut off. Possible Cause and Solution This is normal and indicates that the PortaTone is receiving electrical power. Check that nothing is connected to the PHONES/AUX OUT jack on the rear panel. When a set of headphones is plugged into this jack, no sound is output. Make sure that the following settings are appropriate: Main Voice Volume (#01, page 31), Dual Voice Volume (#11, page 35), and Split Voice Volume (#21, page 37). When setting the Split Point, the keyboard is used only to change the value and does not produce any sound. When using the Dictionary type (Chord Guide, page 62), the keys in the right hand section are used only for entering the chord root and type. The battery power is too low. Replace the batteries. (See page 8.) The External Clock (page 98) has been set to "on,". Change the External Clock setting to "off". • If Local Control (Function #84, page 97) is set to "off," the PortaTone voices will not sound even when playing the keyboard. • If Keyboard Out (Function #82, page 97) is set to "off," the connected MIDI device will not sound when playing the PortaTone keyboard. • Make sure that the Accompaniment Volume (page 55) is set to an appropriate level. • Make sure that the Accompaniment Split Point (#51, page 59) is set to an appropriate value. • Make sure that the Send Level parameter for the effect (and the intended voice: Main, Dual, of Split) is set to an appropriate value. (See pages 31, 35, 37) • Make sure that the corresponding effect is turned on. (See pages 40, 41, 42, 43) • For the Harmony effect, make sure that Harmony Volume (#39, page 44) is set to an appropriate value. This is normal. The Pianist styles have no drums or bass - only piano accompaniment. The accompaniment of the style can only be heard when accompaniment is set to ON and keys are played in the auto accompaniment section of the keyboard. The PortaTone is polyphonic up to a maximum of 32 notes. If the Dual voice or Split voice mode is being used and a style or song is playing back at the same time, some notes/sounds may be omitted (or "stolen") from the accompaniment or song.

TROUBLESHOOTING
Problem
Possible Cause and Solution
When the PortaTone is turned on or off, a
popping sound is temporarily produced.
This is normal and indicates that the PortaTone is receiving
electrical power.
There is no sound even when the keyboard is
played or when a song is being played back.
Check that nothing is connected to the PHONES/AUX OUT jack on
the rear panel.
When a set of headphones is plugged into this
jack, no sound is output.
Make sure that the following settings are appropriate: Main Voice
Volume (#01, page 31), Dual Voice Volume (#11, page 35), and
Split Voice Volume (#21, page 37).
The selected voice does not sound properly, or
is too low in volume.
There is no sound when playing the keyboard.
When setting the Split Point, the keyboard is used only to change
the value and does not produce any sound.
Playing keys in the right hand section of the
keyboard does not produce any sound.
When using the Dictionary type (Chord Guide, page 62), the keys
in the right hand section are used only for entering the chord root
and type.
The sound of the voices or rhythms seems
unusual or strange.
The battery power is too low.
Replace the batteries.
(See page 8.)
The accompaniment does not play back even
when pressing the START/STOP button.
The External Clock (page 98) has been set to “on,“. Change the
External Clock setting to “off”.
There is no sound on either the PortaTone or
the connected MIDI device.
• If Local Control (Function #84, page 97) is set to “off,” the
PortaTone voices will not sound even when playing the keyboard.
• If Keyboard Out (Function #82, page 97) is set to “off,” the
connected MIDI device will not sound when playing the PortaTone
keyboard.
• Make sure that the Accompaniment Volume (page 55) is set to
an appropriate level.
• Make sure that the Accompaniment Split Point (#51, page 59) is
set to an appropriate value.
The accompaniment does not sound properly.
• Make sure that the Send Level parameter for the effect (and the
intended voice: Main, Dual, of Split) is set to an appropriate value.
(See pages 31, 35, 37)
• Make sure that the corresponding effect is turned on.
(See pages
40, 41, 42, 43)
• For the Harmony effect, make sure that Harmony Volume (#39,
page 44) is set to an appropriate value.
The Reverb/Chorus/DSP/Harmony cannot be
heard properly.
When playing back one of the Pianist styles
(#91 - #100), the rhythm cannot be heard.
This is normal.
