WARNING
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or damage to the device or other property. These
precautions include, but are not limited to, the following:
Power supply/Power cord Connections
•Remove the electric plug from the outlet when the devices is not
to be used for extend periods of time, or during electrical storms.
•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.
When removing the electric plug from the device or an outlet,
always hold the plug itself and not the cord. Pulling by the cord
can damage it.
For the SPEAKERS jacks, Use only the included speakers and speaker
cables. Use of other types of speakers and cables may result in damage
to the device(s), or even fire.
Location Handling Precautions
When transporting or moving the device, always use two or more
people. Attempting to lift the device by yourself may damage your
back, result in other injury, or cause damage to the device itself.
Before moving the device, remove all connected cables.
When setting up the device, make sure that the AC outlet you are using
is easily accessible. If some trouble or malfunction occurs,
immediately turn off the power switch and disconnect the plug from
the outlet.
Do not use the device in a confined, poorly ventilated location. Make
sure that there is adequate space between the mixer and surrounding
walls or other devices: at least 1’ ft. at the side, 1’ ft. behind and 1’
ft. above. If the mixer is to be used installed into the speaker cabinet,
make sure to allow adequate space between the speaker and the
surrounding walls or other devices: at least 1’ ft. at the sides, 1’
ft. behind and 1’ ft. above. Inadequate ventilation can result in
overheating, possibly causing damage to the device(s), or even fire.
Do not use the speaker’s handles for suspended installation. Doing so
could result in damage or personal injury.
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 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 or damage to
the internal components.
Do not place the device in an unstable position where it might
accidentally fall over.
Do not block the vents. This mixer has ventilation holes at the top to
prevent the internal temperature from becoming too high. In
particular, do not place the device on its side or upside down.
Inadequate ventilation can result in overheating, possibly causing
damage to the device(s), or even fire.
Do not use the device in the vicinity of a TV, radio, stereo equipment,
mobile phone, or other electric devices. Doing so may result in noise,
both in the device itself and in the TV or radio next to it.
When turning on the AC power in your audio system, always turn on the
device LAST, to avoid speaker damage. When turning the power off, the
device should be turned off FIRST for the same reason.
Do not insert your fingers or hands in any gaps or openings on the device
(vents, ports, etc.).
Avoid inserting or dropping foreign objects (paper, plastic, metal, etc.) into
any gaps or openings on the device (vents, 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 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 immediately.
Do not operate the device if the sound is distorting. Prolonged use in this
condition could cause overheating and result in fire.
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.
Protective Circuit (poly switch)
All full-range loudspeakers are fitted with a self-resetting poly switch that
protects the high-frequency driver from damage caused by excessive power.
If a loudspeaker cabinet loses high-frequency output, immediately remove
power from the unit and wait for two to three minutes. This should be long
enough to allow the poly switch to reset. Reapply power and check the
performance of the high frequency driver before continuing, with the power
reduced to a level that does not cause the poly switch to interrupt the signal.
Interference From Cell Phone
Using a cell phone near the speaker system can induce noise. If this occurs,
move the cell phone further away from the speaker system. Air blowing out
of the bass reflex ports is normal, and often occurs when the speaker is
handing program material with heavy bass content.
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 service personnel about
replacing defective parts.
The manufacturer will not be responsible for damage caused by
improper use or modification to the device.
