DME64N/DME24N Owner’s Manual 5
• 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 qualifi ed Yamaha service
personnel about replacing defective components.
