CARE OF YOUR SUBWOOFER
Do not use any harsh detergents or chemicals to clean the
cabinet. Abrasives, detergents, or cleaning solutions will damage
the finish on the cabinet. We recommend using a damp cloth to
clean the front, back and sides.
During normal conditions, the subwoofer may be left on
continuously without any problems. If you plan to leave the unit
unused for an extended period of time, we recommend that you
turn off the unit by the master power switch on the rear panel.
TROUBLESHOOTING AND SERVICE
Before seeking service for your subwoofer, please re-check
all systems. Following is a simple troubleshooting guide to
assist you.
1. Verify that the unit is plugged in and power outlet used
is active.
2. Is the power switch on?
3. Is the unit receiving an input signal from your source?
4. Have all controls on the subwoofer (volume, crossover,
phase, etc.) been properly set?
5. If the unit has been running at high levels, one of the
protection circuits may be engaged. Has the built-in
amplifier overheated?
6. Has the power button been depressed on the remote?
If the protection circuitry is active, the unit may cycle on and off
until operating parameters return to normal. Under more serious
conditions, the unit may shut off completely. Normal operation
should return upon cooling, but you may be required to turn the
power off and then on again to reset the unit.
The following conditions require service by a qualified technician:
1. The power cord has become damaged
2. The unit does not appear to operate normally or exhibits a
marked change in performance
3. The unit has been exposed to water
4. Some part of the cabinet or circuitry is physically damaged
