Troubleshooting
If you experience problems, refer to the relevant item
and take the appropriate measures.
Power supply
Power does not turn on
• Is the power cable connected to an outlet? For more
information, see “Connections” on page 37.
• Is the POWER switch turned on?
• Turn on the rear panel POWER switch. See
“Turning the power on/off” on page 40.
LCD screen
Display is blank or incorrect
The power is turned on, but nothing is shown in
the LCD screen. However, the OASYS functions
normally when you play the keyboard or perform
other operations.
• Are the LCD screen’s color, contrast, and backlight
brightness adjusted correctly?
1. Press the GLOBAL switch, and then press the
EXIT switch twice.
2. Hold down the ENTER switch, and press numeric
key 6.
3. Press the UTILITY RESET CONTROLS switch.
The display will be reset to the standard settings.
4. Press the EXIT switch.
The power is turned on, but the LCD screen does
not display normally, or an error message is
displayed. There is no sound when you play the
keyboard, and the OASYS does not function
normally.
It is possible that the system has been damaged. Use
the included restore CD to restore the OASYS to its
factory state.
Problems using the touch-screen
Can’t operate the LCD screen correctly
On the Basic Setup tab of the Global P0 page, use the
Touch Panel Calibration page menu command to
adjust the touch panel response.
Note: If you are unable to select commands from the
page menu, do the following:
1. Press the GLOBAL switch.
2. Press the EXIT switch twice.
3. Hold down the ENTER switch and press 3 on the
numeric keypad.
The Touch Panel Calibration page will appear. Follow
the on-screen instructions to re-calibrate the touch
panel.
Can’t switch modes or pages
If you’re doing any of the following, you may not be
able to change modes or switch to a different page:
• Recording or playing back a song or pattern
• Sampling
• Playing a CD
• Playing a WAVE file
In Combination, or Sequencer modes, can’t edit
the value of Timbre/Track parameters such as MIDI
Channel or Status
Some parameters can’t be edited while notes are
playing, either locally or from MIDI. If the damper
pedal is held down, or if its calibration is incorrect,
notes may be sustaining even if they aren’t audible.
• Are you using a damper pedal with a polarity that
does not match the Damper Polarity setting (Global
P2: Controller/Scale)? For more information, see
“Damper Polarity,” on page 659 of the Parameter
Guide.
• In some cases, this problem can be solved be
executing the page menu command Half Damper
Calibration (Global P0: Basic Setup). For more
information, see “Half Damper Calibration,” on
page 683 of the Parameter Guide.
No beep sounds when you touch the LCD screen
Check the Beep Enable check box (Global P0: Basic
Setup). For more information, see “Sounding a beep
when you press the LCD screen” on page 148.
