Handling and Maintenance

• Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile phone or other electric
devices that may generate electrical and RF noise.
• Do not expose the device to excessive dust, vibration, extreme cold or heat (e.g. direct sunlight, near
a heater, in car during the day) in order to prevent the possibility of panel disfiguration, unstable opera-
tion or damage to the internal components.
• Do not place vinyl, plastic, or rubber objects on the device as this may discolour the panel.
• When cleaning the device use a soft dry cloth. Do not use paint thinners, solvents, cleaning fluids or
chemically impregnated wiping cloths.
• Condensation can occur in the device due to drastic changes in ambient temperature, when the
device is suddenly moved from one location to another where the environmental conditions a different.
Using the device while condensation is present can cause damage.
• Avoid setting all equalizer controls and faders to their maximum setting. Depending on the condition
of the connected devices, doing so may cause feedback and potentially damage the speakers.
• Do not apply oil, grease or contact cleaner to the faders. Doing so may cause problems with electri-
cal 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.

• Before connecting the computer to the mixer's USB 2.0 terminal, exit from any power-saving modes
of the computer (suspend/sleep/standby).
