PRECAUTIONS

PLEASE READ CAREFULLY BEFORE PROCEEDING

* Please keep this manual in a safe place for future reference.

WARNING

Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from

electrical shock, short-circuiting, damages, ﬁre or other hazards. These precautions include, but are not limited

to, the following:

• Only use the voltage speciﬁed as correct for the device. The required

voltage is printed on the name plate of the device.

• Use only the speciﬁed power cord.

• Do not place the power cord near heat sources such as heaters or

radiators, and do not excessively bend or otherwise damage the cord,

place heavy objects on it, or place it in a position where anyone could walk

on, trip over, or roll anything over it.

• Be sure to connect to an appropriate outlet with a protective grounding

connection. Improper grounding can result in electrical shock.

• Do not open the device or attempt to disassemble the internal parts or

modify them in any way. The device contains no user-serviceable parts. If

it should appear to be malfunctioning, discontinue use immediately and

have it inspected by qualiﬁed Yamaha service personnel.

• Do not expose the device to rain, use it near water or in damp or wet

conditions, or place containers on it containing liquids which might spill

into any openings.

• Never insert or remove an electric plug with wet hands.

• If the power cord or plug becomes frayed or damaged, or if there is a

sudden loss of sound during use of the device, or if any unusual smells or

smoke should appear to be caused by it, immediately turn off the power

switch, disconnect the electric plug from the outlet, and have the device

inspected by qualiﬁed Yamaha service personnel.

• If this device should be dropped or damaged, immediately turn off the

power switch, disconnect the electric plug from the outlet, and have the

device inspected by qualiﬁed Yamaha service personnel.

CAUTION

Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or

damage to the device or other property. These precautions include, but are not limited to, the following:

•Remove the electric plug from the outlet when the device is not to be used

for extended periods of time, or during electrical storms.

•When removing the electric plug from the device or an outlet, always hold

the plug itself and not the cord. Pulling by the cord can damage it.

• Before moving the device, remove all connected cables.

• When setting up the device, make sure that the AC outlet you are using is

easily accessible. If some trouble or malfunction occurs, immediately turn

off the power switch and disconnect the plug from the outlet. Even when

the power switch is turned off, electricity is still ﬂowing to the product at

the minimum level. When you are not using the product for a long time,

make sure to unplug the power cord from the wall AC outlet.

•Avoid setting all equalizer controls and faders to their maximum.

Depending on the condition of the connected devices, doing so may cause

feedback and may damage the speakers.

• Do not expose the device to excessive dust or vibrations, or extreme cold

or heat (such as in direct sunlight, near a heater, or in a car during the day)

to prevent the possibility of panel disﬁguration or damage to the internal

components.

•Do not place the device in an unstable position where it might accidentally

fall over.

• Do not block the vents. This device has ventilation holes at the front and

rear to prevent the internal temperature from rising too high. In particular,

do not place the device on its side or upside down, or place it in any

poorly-ventilated location, such as a bookcase or closet.

• Do not use the device in the vicinity of a TV, radio, stereo equipment,

mobile phone, or other electric devices. Otherwise, the device, TV, or radio

may generate noise.

• Before connecting the device to other devices, turn off the power for all

devices. Before turning the power on or off for all devices, set all volume

levels to minimum.

• Be sure to connect to a properly grounded power source. A ground screw

terminal is provided on the rear panel for safely grounding the device and

preventing electrical shock.

• Remove the power plug from the AC outlet when cleaning the device.

• Do not insert your ﬁngers or hand in any gaps or openings on the device

(vents, ports, etc.).

• Condensation can occur in the device due to rapid, drastic changes in

ambient temperature—when the device is moved from one location to

another, or air conditioning is turned on or off, for example. Using the

device while condensation is present can cause damage. If there is reason

to believe that condensation might have occurred, leave the device for

several hours without turning on the power until the condensation has

completely dried out.

•Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.)

into any gaps or openings on the device (vents, ports, etc.) If this

happens, turn off the power immediately and unplug the power cord from

the AC outlet. Then have the device inspected by qualiﬁed Yamaha service

personnel.

•Do not use the device or headphones for a long period of time at a high or

uncomfortable volume level, since this can cause permanent hearing loss.

If you experience any hearing loss or ringing in the ears, consult a

physician.

• Do not rest your weight on the device or place heavy objects on it, and

avoid use excessive force on the buttons, switches or connectors.

This device has a built-in backup battery that maintains data in internal

memory even when the device’s power is switched off. The backup battery

will eventually become depleted, however, and when that happens the

contents of the internal memory will be lost.* To prevent loss of data be sure

to replace the backup battery before it becomes fully depleted. When the

remaining capacity of the backup battery becomes so low that it needs to be

replaced a “Low Battery” or “No Battery” message will appear on the display

during operation or when the device is powered on. If either of these

messages appears do not turn off the power and immediately transfer any

data you want to save to a computer or other external storage device, then

have qualiﬁed Yamaha service personnel replace the backup battery. The

average life of the internal backup battery is approximately 5 years,

depending on operating conditions.

* Data items maintained in the internal memory by the backup battery are as

follows:

• Current scene parameters and number.

• Device parameters (SLOT, HA, UTILITY, Master Mute/Level, etc.).

• Event log.

Data items other than those described above are stored in memory that does

not require backup power, and will be retained even if the backup battery

fails.

Do not turn the [POWER] switch on and off repeatedly and rapidly. Be sure to wait six seconds or more between turning the power to the unit off and then on.

Always turn the power off when the device is not in use.

The performance of components with moving contacts, such as switches, volume controls, and connectors, deteriorates over time. Consult qualiﬁed Yamaha service

personnel about replacing defective components.
