Dangerous voltage inside the subwoofer enclosure, please do not open the chassis. 
Refer to qualified personnel for servicing.
Please remove the power plug if the system is unused for long period of time.
Please do not expose the system in rain or moisture environment.
Please do not place vase or utensil full of liquid on the speaker.

Troubleshooting

Not all speakers function:

Please first check if the speaker wires are connected securely; 

then check if the Line-in connectors are reversed; check also if the audio source is at fault.

One satellite speaker does not function when playing CD from computer:

This kind of phenomena is prone to happen on new computer systems that one satellite does not function when playing CD, 

but system works fine when playing WAV formatted files. This is mainly due to the fault connection of CD-ROM and sound 

card, that one channel of signal is shorted to the ground. Please refer to the manual of CD-ROM and sound card to adjust 

the wire connection.

 

System does not work at all

1. Please check if power is connected, and if the wall outlet is switched on.

2. Please check if the amplifier is still in STBY mode

3. Please check if the master volume is turned to minimum

4. Please check if the audio input cable is connected correctly

5. Please check if there is signal from audio source

Noise coming from speakers

Amplifier circuitry of this product generates little noise, while the background noise of some VCD/DVD player or computer 

sound card are too high. Please keep the system in active mode and remove the audio source, if no sound can be heard at 

1 meter away from the system, then there is no problem with this product.

Magnetic interference

This system is complete magnetically shielded, and can be placed near TV or monitor. But since magnet of the subwoofer 

driver is large, some magnetism leakage is inevitable when the system is too close to the monitor, and it is recommended to 

keep a 1 meter distance between the speaker system and monitor or TV set.

System can not switch to analog signal input with digital input ports plugged in

Some digital signal source like CD or VCD play will still output tangible digital signal even when the source is shut down. 

These tangible signals are used to mute the decoder; therefore the system can not switch to analog inputs (digital inputs 

have higher priority). Power off the source of digital signal or unplug the optical or coaxial inputs, then the system will switch 

to analog inputs.

System does not work with Dolby Digital (AC-3) signal

Digital inputs on this system do not support Dolby Digital (AC-3) formatted signals, so the system will not work when such 

signals are fed in.

When product can not memorize the settings from last power-off

Please turn on the system and adjust to the desired volume and EQ setting. Before powering off the system, MAKE SURE 

to send the system to STBY mode first by pressing the STBY button on wired controller or wireless remote controller; 

otherwise the current setting will be lost.
