15ENGLISH• This unit is equipped with a high-speed protection circuit. The purpose of this circuit is to protect the speakers undercircumstances such as when the output of the power amplifier is inadvertently short-circuited and a large current flows, whenthe temperature surrounding the unit becomes unusually high, or when the unit is used at high output over a long periodwhich results in an extreme temperature rise.When the protection circuit is activated, the speaker output is cut off and the power supply indicator LED flashes. Shouldthis occur, please follow these steps: be sure to switch off the power of this unit, check whether there are any faults withthe wiring of the speaker cables or input cables, and wait for the unit to cool down if it is very hot. Improve the ventilationcondition around the unit and switch the power back on.If the protection circuit is activated again even though there are no problems with the wiring or the ventilation around theunit, switch off the power and contact a DENON service center.Protector circuit• The protector circuit may be activated if the set is played for long periods of time at high volumes when speakers with animpedance lower than the specified impedance (for example speakers with an impedance of lower than 4 Ω/ohms) areconnected. If the protector circuit is activated, the speaker output is cut off. Turn off the set’s power, wait for the set to cooldown, improve the ventilation around the set, then turn the power back on.Note on speaker impedance
