Handling and Maintenance

• Do not use the device in the vicinity of a TV, radio, stereo
equipment, mobile phone, or other electric devices. Oth-
erwise, the device, TV, or radio may generate noise.
• Do not expose the device to excessive dust or vibrations,
or extreme cold or heat (such as in direct sunlight, near a
heater, or in a car during the day) to prevent the possibility
of panel disfiguration, damage to the internal components
or unstable operation.
• Do not place vinyl, plastic or rubber objects on the device,
since this might discolor the panel of this device.
• When cleaning the device, use a dry and soft cloth. Do
not use paint thinners, solvents, cleaning fluids, or chemi-
cal-impregnated wiping cloths.
• Condensation can occur in the device due to rapid, dras-
tic 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 con-
densation 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 setting all equalizer controls and faders to their
maximum. Depending on the condition of the connected
devices, doing so may cause feedback and may damage
the speakers.
• Do not appl y oil, grease, or contact cleaner to the faders.
Doing so may cause problems with electrical contact or
fader motion.
• 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.
