How to exit from the test modeOnly reset the unit.(Note) The test mode cannot be terminated by ACC OFF, powerOFF, momentary power down or panel detached

47、.3. Initial status in the test mode Sources : ALL OFF Display : All segments are lit. Volume : -10 dB (displayed as “30“) Loudness : OFF CRSC : OFF regardless of the presence of switchingfunction. SYSTEM Q : Flat4. Special display in Tuner modeWhen any of the following messages is displayed in Tuner

48、 mode,the F/E may be abnormal. “TNE2P NG“ : The EEPROM is set to the default (unstablevalues) because the F/E was shipped without passing throughthe adjustment process, etc. “TNCON NG“ : Communication with the F/E is not possible.5. Forced switching of K3IEach press of the Preset 6 key in Tuner mode

49、 should switch K3Ifrom AUTO Forced Wide Forced Middle Forced Nar-row AUTO.The initial status is AUTO and the display shows these modesas follows. AUTO : FMA Forced Wide : FMW Forced Middle : FMM Forced Narrow : FMN6. Audio-related specifications A short press of the Q key initiates the audio adjustment mode. Continuous holding of a remote control key is inhibited. Bass, Middle and Treble are adjusted in 3 steps of Min / Flat /Max with the Track Up/Down keys. Balance is adjusted in 3 steps of Left Max / CENTER / R
