Yamaha 1009MWTO-F0 - Manual (Page 5)

DME64N/DME24N Owner’s Manual 5
• 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.).
• 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.
NOTICE
To avoid the possibility of damage to the product, data or other property, follow the notices below.
 Handling and Maintenance
• 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.
• 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.
• 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.
• 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.
