IMX644 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.
• The included power cable has a three-conductor plug, so if the AC outlet is
grounded the IMX644 will be grounded appropriately.
• 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
(ports, etc.).
•Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any
gaps or openings on the device (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 apply oil, grease, or contact cleaner to the faders. Doing so may cause
problems with electrical contact or fader motion.
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.
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.
