CHT-R User’s Manual
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.
Has the built-in amplifier overheated?
6. Has the power button been depressed on the remote?
7. Is the remote non-responsive? We recommend replacing the batteries in 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 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.
Thank You for Purchasing a Velodyne!
