TEST MODE

●How to enter the test mode

In order to enter the test mode, reset the unit while simultaneously pressing down [1] and [3] keys.

●How to clear the test mode

The test mode is cleared in case of any of the following e v ents: resetting, momentary power down, Acc OFF, P ower OFF and removal of the panel.

●Initial conditions of the test mode

• Source is STANDBY.

• Displays lights are all turned on.

• The volume is at -10dB (The display is 30).

• Loudness (LOUD) is OFF.

• CRSC is OFF, regardless of whether there are switching functions or not.

• SYSTEM Q is NATURAL (=FLAT).

• BEEP will sound anytime with a short push.

•Auxiliary (AUX) is ON.
