TEST MODE

1. How to enter the test mode
Reset the unit while holding preset 1 key and preset 3 key. Track jump takes place to the following track when the Track up key is pressed. No. 9 No. 15 No. 10 No. 11 No. 12 No. 13 No. 14 No. 9 (The cycle restarts from here.) When the Track down key is pressed, track returns back by one track during playback.
2. How to exit from the test mode
RESET POWER OFF ACC OFF Bu OFF Panel detach

7. Audio system

The product enters the audio adjustment mode when the Q key is pressed momentarily. Continuous advance operation from remote control is prohibited. The Bass/Middle/Treble is adjusted to either one of the 3 steps of MIN/Center/MAX with Track up/down key. Balance is adjusted to either one of the 3 steps of Left MAX/Center/Right MAX with Track up/down key. Fader is adjusted to either one of the 3 steps of Rear MAX/Center/Front MAX with Track up/down key. HPF (high-pass filer) is adjusted to either Through or 220 Hz with Track up/down key. LPF (low-pass filer) is adjusted to either Through or 120 Hz with Track up/down key. Bass f/Bass Q/Bass EXT/Middle f/Middle Q/Trable f do not appear on the audio adjustment.
3. Initial status in test mode
Sources Display Volume LOUD CRSC SYSTEM Q BEEP DEMO : ALL OFF : All segments are lit. : -10 dB (displayed as 30) : OFF : OFF regardless of the presence of switching function. : Flat : ON : OFF
4. Special display during Tuner mode
If the following display appears during the TUNER mode, the front end is defective. "TNE2P NG": EEPROM remains in the initial value (don't care) because the product is shipped without passing the F/E adjustment process. "TNCON NG": Communication with the F/E is not possible.

8. MENU system

The product enters the MENU mode when the CLK key is pressed momentarily. The product enters the MENU mode when the DNPP/ SBF key of the remote control is pressed. Continuous advance operation from remote control is prohibited. The calendar adjustment, calendar display switching and calendar memo are deleted from the advance operation. (FL model) Red is set by the preset 1, blue by 2, green by 3 and white by 4 in the color adjustment mode. (VCLD model) Contrast can be adjusted in 3 steps of 0/5/10. Initial value is 5. (VCLD/VCLD model) Brightness can be adjusted in 3 steps of 0/5/10. Initial value is 10. (Normal FL model)

CAUTION:For continued safety, replace safety critical components only with manufacturers recommended parts (refer to, parts list). Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be carried out (exposed parts are acceptably insulated from the supply circuit) before the appliance is returned to the customer.
DC voltages are as measured with a high impedance voltmeter. Values may vary slightly due to variations between individual instruments or/and units.
