Possible Cause and Solution
This is normal and indicates that the instrument
is receiving electrical power.
Check if any cable or headphone is connected to
the PHONES jack on the rear panel. When a set
of headphones is plugged into this jack, no sound
will be produced.
The batteries are low or dead. Replace all six
batteries with completely new ones, or use the
optional AC adaptor.
