*This unit is equipped with a protection circuit. A brief interval (a few seconds) after power up is required before the unit will operate normally. You should also turn down the volume level to protect the unit from any sudden peak in volume. Even with the volume all the way down, you may still hear some sound when the power is switched on, but this is normal, and does not indicate a malfunction.
