DME8i-C/DME8o-C/DME4io-C Owner’s Manual

• 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.
• Do not insert your fingers or hands in any gaps or openings on the device.
• 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. 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 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 backup battery charge
becomes low, the [ERROR] indicator on the front panel blinks (For details, refer
to “Error Messages” on page 42).
In this case, 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 (CobraNet, 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.
The rubber feet included in this package can be attached to the bottom of this device to prevent slippage when it is to be used on a slipper y surface.
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.
