SB168-ES 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, etc.).
• Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into any
gaps or openings on the device (vents, 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 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. When you unplug the power cord from
the AC outlet, the internal head amp settings are retained. However, if the backup
battery fully discharges, these settings will be lost. Imminent battery depletion is
indicated by the panel LEDs, as described on page 21. In this case, immediately
save the data to a compatible digital mixer, then have qualified Yamaha service
personnel replace the backup battery.
Always turn the power off when the device is not in use.
The performance of components with moving contacts, such as switches, and connectors, deteriorates over time. Consult qualified Yamaha service personnel about replacing
defective components.
