Upon switching ON the amplifier using the power button (1), the green Power On LED (2) lights up. The VU-bar
shows the output level of the amplifier. If the internal temperature of the booster reaches a critical limit, due to poor
ventilation or overload, an overheat protection circuit switches OFF the power stage.
LBB1938 only:
The overheat indicator (4) lights up if the power stage is switched OFF by the overheat protection circuit. The
battery operation indicator (3) lights up if the mains power supply is failing and the back-up battery is in use.
