Audio Problems
CAUTION: DO NOT TROUBLE SHOOT AUDIO PROBLEMS USING
HEADPHONES. ADDITIONALLY, ALWAYS BE AWARE OF THE VOLUME
LEVELS ON THE SP5 AND ON THE CONNECTED AUDIO SYSTEM OR MIXER.
NOTE: When diagnosing audio problems, set the SP5 to play its demo sequence rather then
intermittently pressing keys. This will prevent any unexpectedly loud volume changes.
