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. Use a soft cloth with a good quality furniture polish
to clean the hand-rubbed, black lacquer, painted top.
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 unit receiving an input signal from your source?
4. Have all controls on subwoofer (volume, crossover, phase, etc.)
been properly set?
5. If unit has been running at high levels, one of the protection
circuits may be engaged.
6. Has the built-in amplifier overheated?
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 will
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.
