In an overload condition, the LR-100 will go into a protective state to protect the unit and power supply from excessive current and heat. This condition will occur if the speaker termi- nals are shorted to each other or if they are shorted to the chassis for over 15 seconds. In this condition, the LR-100 will no longer function normally. If the LR-100 stops functioning nor- mally, do the following:

1.Turn the unit off and unplug it from power. If you are operating the LR-100 with an external +12VDC source such as a battery, disconnect the power source from the unit.

2.Remove the short to the speaker terminals.

3.Wait 30 seconds or longer.

4.Plug the unit back in and turn the power on.

The LR-100 should now function normally. If the unit is still not functioning normally, contact Listen Support (see page 21).
