SAFETY INSTRUCTIONS
Please read all the instructions herein. Please retain this manual safely for future reference.
Please heed all safety warnings. Please install in accordance with the manufacturer's instructions.
Please adjust the volume control to a comfortable level to avoid damaging your hearing and the system.
WARNING:
TO REDUCE THE RISK OF ELECTRIC SHOCK:
Do not expose this apparatus to rain or moisture.
Do not use the speakers near water, and do not immerse them in any liquid or pour any liquid on them.
Do not block the openings in the speaker cabinets, never push objects into speaker vents or slots because
of fire or electric shock hazards, and provide sufficient space around the speakers for proper ventilation.
Do not install near any heat sources such as radiators, heaters, stoves, or other apparatus (including
amplifiers) that produce heat.
Do not defeat the safety purpose of the polarized plug. A polarized plug has two blades with one wider than
the other. The wider blade is provided for your safety. If the provided plug does not fit into your outlet, consult
an electrician for replacement of the obsolete outlet. Protect the power cord from being walked on or pinched
particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
Unplug this apparatus when unused for long periods of time.
Place the speakers in a stable location so that it will not fall causing damage to the speakers or bodily harm.
Unplug the speakers from the computer and from the electrical outlet before cleaning them with a damp cloth.
For added protection during lightning storms, unplug the speakers from the electrical outlet and turn off the
computer.
Servicing is required when the apparatus has been damaged in any way, such as the power-supply cord or
plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been
exposed to rain or moisture, does not operate normally, or has been dropped. Refer all servicing to qualified
service personnel only.

Edifier One Year Limited Warranty
Edifier warrants to the end user that all of its computer speaker systems are free from defects in materials and
workmanship in the course of normal and reasonable use for a term of one year from the date of purchase.
This warranty is the exclusive and only warranty in effect relative to Edifier multimedia speaker systems and any
other warranties, either expressed or implied, are invalid. Neither Edifier nor any authorized Edifier reseller is
responsible for any incidental or consequential damages incurred in the use of the speakers. (This limitation of
incidental or consequential damage is not applicable where prohibited.)
Edifier's obligation under this warranty does not apply to any defect, malfunction or failure as a result of misuse,
abuse, improper installation, use with faulty or improper equipment, or the use of the speaker systems with any
equipment for which they were not intended.
The terms of this warranty apply only to speaker systems when such speakers are returned to the respective
authorized Edifier reseller where they were purchased.

Troubleshooting Guide
System does not function at all:
Check if the AC power adapter is plugged into a power outlet, which has been
switched on. (AC power adapter is optional in some world markets).
Check if all speaker cable connections are correct.
Check if your external sound source equipment is working correctly.
Sound from only one driver:
1. Check if all speaker cable connections are correct.
2. Try an alternate sound source such as a CD player or an MP3 player, in case the
original sound source is at fault.
3. Check if the computer soundcard is installed correctly.
When playing an audio CD from a computer, only one driver has sound:
This generally occurs with a new computer when only one driver works when playing
an audio CD, but both speakers function correctly when running a WAV file or playing
a game. The reason for this is that the CD-ROM does not match the soundcard, or
one channel of the signal maybe shorted to a ground wire. Please refer to your
computer's operational manual to adjust the CD-ROM connections.
Music is distorted at maximum volume when the system is powered by the USB
port of the computer:
This tends to happen as the USB port is unable to supply sufficient power for the
speaker system. Please adjust the volume to a reasonable level, or please use a centerpositive AC adapter with 5V D.C. output.
Excessive noise from Speakers:
Edifier's speakers feature a very low noise circuit design. Your external sound source
equipment may have a poor signal-to-noise ratio. Unplug the input audio cable, and
check if the noise is from the CD/DVD player or the computer soundcard, etc.
Magnetically Shielded Speakers:
Subwoofers and satellites speakers of Edifier's product
can place the speakers near a TV or monitor. Allow a 0.2-1 distance between the
speakers and monitor to avoid possible magnetic field interference.
