Precautions
Warnings
1. Connect this unit’s power cord only to an AC
outlet of the type stated in this Owner’s Man-
ual or as marked on the unit. Failure to do so is
a fire and electrical shock hazard.
2. Do not allow water to enter this unit or allow
the unit to become wet. Fire or electrical shock
may result.
3. Do not place heavy objects, including this unit,
on top of the power cord. A damaged power
cord is a fire and electrical shock hazard. In
particular, be careful not to place heavy objects
on a power cord covered by a carpet.
4. Do not place a container with liquid or small
metal objects on top of this unit. Liquid or
metal objects inside this unit are a fire and elec-
trical shock hazard.
5. Do not remove the unit’s cover. You could
receive an electrical shock. If you think internal
inspection, maintenance, or repair is necessary,
contact your dealer.
6. Do not modify the unit. Doing so is a fire and
electrical shock hazard.
7. If lightning begins to occur, turn off the power
switch of the unit as soon as possible, and
unplug the power cable plug from the electrical
outlet.
If there is a possibility of lightning, do not
touch the power cable plug if it is still con-
nected. Doing so may be an electrical shock
hazard.
8. If the power cord is damaged (i.e., cut or a bare
wire is exposed), ask your dealer for a replace-
ment. Using the unit with a damaged power
cord is a fire and electrical shock hazard.
9. If you notice any abnormality, such as smoke,
odor, or noise, or if a foreign object or liquid
gets inside the unit, turn it off immediately.
Remove the power cord from the AC outlet.
Consult your dealer for repair. Using the unit
in this condition is a fire and electrical shock
hazard.
10. Should this unit be dropped or the cabinet be
damaged, turn the power switch off, remove
the power plug from the AC outlet, and contact
your dealer. If you continue using the unit
without heeding this instruction, fire or electri-
cal shock may result.
Cautions
1. Keep this unit away from the following loca-
tions:
Locations exposed to oil splashes or steam,
such as near cooking stoves, humidifiers, etc.
Unstable surfaces, such as a wobbly table or
slope.
Locations exposed to excessive heat, such as
inside a car with all the windows closed, or
places that receive direct sunlight.
Locations subject to excessive humidity or
dust accumulation.
2. Do not place the power cord close to a heater. It
may melt, causing fire or electrical shock.
3. Hold the power cord plug when disconnecting
it from an AC outlet. Never pull the cord. A
damaged power cord is a potential fire and
electrical shock hazard.
Do not touch the power plug with wet hands.
Doing so is a potential electrical shock hazard.
4. Use extreme caution when using a speaker
stand and speaker bracket.
5. To relocate the unit, turn the power switch off,
remove the power plug from the AC outlet,
and remove all connecting cables. Damaged
cables may cause fire or electrical shock.
6. Turn off all musical instruments, audio equip-
ment, and speakers when connecting to this
unit. Use the correct connecting cables and con-
nect as specified.
Always lower the volume control to minimum
before turning on the power to this unit. A sud-
den blast of sound may damage your hearing.
7. Do not output distorted sounds for long peri-
ods of time, as this will cause the speaker to
heat up, leading to a fire hazard.
8. If you know you will not use this unit for a
long period of time, such as when going on
vacation, remove the power plug from the AC
outlet. Leaving it connected is a potential fire
hazard.
9. To prevent electrical shock when cleaning the
unit, remove the power plug from the AC out-
let.
10. The inside of the unit should be cleaned peri-
odically. Dust accumulation inside the unit
may cause malfunction and is a potential fire
hazard. Consult your dealer for information
about cleaning.
Backup battery
The unit contains a long-life lithium battery which maintains the contents of the buffer and user
memory locations even when the unit is off. With normal use, the battery should last approximately 5
years. If the battery voltage falls below a certain level, a “***WARNING*** LOW BATTERY” message
will appear on the screen when the power is turned on. If this occurs, have the battery replaced by at
a qualified Yamaha service center. Do not attempt to replace the battery yourself!
