5) Troubleshooting
Should your speakers not work properly, check the following:
No sound from speakers or quiet/strange sound:
Make certain you observed proper polarity for both speaker inputs. Check the connections at the back of the receiver, and then at the speaker.
Verify that the amplifier is powered on and the volume is turned up.
Check that the correct transformer tap is selected for your application. If you are using a stereo amplifier or a receiver, use the 4-ohm tap.
Mute feature or protection mode is activated. Check for short circuits in speaker wiring.
One speaker is playing while the other is not playing or plays quietly:
Check the balance control on the receiver. Make sure it is centered.
Loose connection at either the receiver or the speaker. Double check connections.
Bad speaker cable. Replace the suspect speaker cable.
Amplifier/Receiver cuts on and off:
This could be caused by a short circuit between the positive and negative leads. Check the connections at the back of the receiver,
and then at the speaker; make sure that no strands of wire from one connector are touching the other connector
.

Caring For Your Speakers
The two most common ways that loudspeakers are permanently damaged:
1)
Not enough power at higher volumes.
2)
Too much power at higher volumes.
Contrary to conventional wisdom, far more speakers are damaged as a result of under-powering, than by overpowering. When an amplifier runs out of
power, it still tries to reproduce the musical signal by “clipping” the waveform. At high volume levels this clipping sends extreme amounts of distortion
energy to the speaker, eventually destroying it. If the sound from your speakers starts to sound distorted, turn down the volume.
Having plenty of reserve power will help your speakers reproduce dynamic contrasts and quick transients of music much more effectively, but use good
judgment; too much power will also permanently damage a speaker. Again, if you hear distortion or audible distress, turn the volume down.
The CS90B speakers are designed to withstand outdoor environments, including incidental exposure to water. They are not designed to be washed using
a pressure washer or hose nozzle. If debris accumulates on the housing of the speaker, use a damp sponge or cloth to remove it. This product is not suit-
able for washdown duty or locations requiring explosion-proof electrical hardware.
