M7CL Owner’s Manual
• When turning on the AC power in your audio system, always turn on the power
amplifier LAST, to avoid speaker damage. When turning the power off, the power
amplifier should be turned off FIRST for the same reason.
• 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 insert your fingers or hands in any gaps or openings on the device
(vents).
•Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any
gaps or openings on the device (vents) 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.
• Do not apply oil, grease, or contact cleaner to the faders. Doing so may cause
problems with electrical contact or fader motion.
• 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 is running
low, the LCD display indicates “Low Battery!” when you starting up the system,
(In this case, the Battery field indicates “LOW” or “NO” in the SETUP screen.)
immediately save the data to a USB 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.
• Library data.
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.
Handling caution Backup battery
XLR-type connectors are wired as follows (IEC60268 standard): pin 1: ground, pin 2: hot (+), and pin 3: cold (-).
Yamaha cannot be held responsible for damage caused by improper use or modifications to the device, or data that is lost or destroyed.
