Troubleshooting - Yamaha CNR-35 3 CNR-55 Owner's Manual

Troubleshooting

A cracking noise is sometimes
heard.
Interference from radio, TV, or
other sources occurs.
12
The sound of the CNR-35/55
causes surrounding objects to
resonate.
The sound is too soft, despite
the volume being set to the
maximum.
Chord/bass accompaniment
doesn't sound at all while play-
back of the rhythm patterns even
though playing the chords in the
Auto Accompaniment Section of
the keyboard (C1 - F#2).
Please note that the appearance of any of the following
phenomena does not indicate a mechanical failure of the
CNR-35/55.
Problem Possible Cause and Solution
Noise may be produced when either an electrical ap-
pliance is turned on or off, or an electric power tool
(such as drill) is used in the proximity of the CNR-
35/55. If this occurs, plug the CNR-35/55 into an
electrical outlet located as far as possible from the
device that seems to be the source of the problem.
This is caused by the proximity of a high-power
broadcasting station or amateur ham radio setup.
Because the CNR-35/55 is capable of producing
powerful bass sounds, resonance may be caused in
surrounding objects, such as cabinets or glass win-
dows. To avoid this, relocate the objects or lower the
CNR-35/55's volume.
Check all of the volume controls, making sure that
they are set to suitable levels: the ACCOMP./
RHYTHM VOL. control (When using rhythm / ac-
companiment) and the Expression Pedal as well as
the MASTER VOLUME control.
Check that the CNR-35/55 is not in "Automatic Ac-
companiment Off" condition. (See page 10)
If the instrument is in that condition, simply turn the
POWER off then turn it on again.
