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 at appropriate levels.
When using a mobile phone, noise is produced.
Using a mobile phone in close proximity to the AK140 may
produce interference. To prevent this, turn off the mobile phone
or use it further away from the AK140.
The auto accompaniment does not play back an even Sync after 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 to play a key in the left–hand range of
the keyboard.
