PROBLEM
POSSIBLE CAUSE AND SOLUTION
The speakers produce a pop sound whenever the power is turned
ON or OFF.
This is normal and is no cause for alarm.
There is no sound when the keyboard is played.
Make sure the master volume is set to an appropriate level. Check
if headphones are plugged into the PHONES/OUTPUT jack. The
R1/R2/L voice volume (Mixer) settings could be set too low. Make
sure the voice volumes are set at appropriate levels.
When using a mobile phone, noise is produced.
Using a mobile phone in close proximity to the AK280 may
produce interference. To prevent this, turn off the mobile phone
or use it further away from the AK280.
The auto accompaniment does not play back even when Sync is
in standby and a key is pressed.
You may be trying to start accompaniment by playing a key in the
right hand range of the keyboard. To start the accompaniment
with Sync Start, make sure you play a key in the left–hand range
of the keyboard.
Certain notes sound like they have a wrong pitch.
Make sure that the tuning value is set to 0. Press and hold the [+/
YES] and [–/NO] buttons simutaneously, then turn the power on
to set INSTRUMENT to default.
The Harmony function does not operate.
Please make sure the Harmony function is on. Harmony cannot
be turned on when a drum kit is selected for the
voice R1.
Note:
If you notice any abnormality that cannot be handled, please contact a provider or repair man, and have the AK280 inspected by
qualified service personnel.
