TEST MODE SPECIFICATIONS

(1) How to enter the test mode

TEST MODE

3. Press and hold the AUDIO key for 1 second to enter menu mode. 4. Press the FM/AM key to select "SECURITY". 5. Press and hold the Track Up/Down for 2 seconds. 6. Enter the code by pressing the Preset 1, 2, 3 and 4 keys. Example: To enter "3510", Press the Preset 1 key 4 times. Press the Preset 2 key 6 times. Press the Preset 3 key 2 times. Press the Preset 4 key once. 7. Press and hold the DISPLAY key for 3 seconds to display "APPROVED". 8. Quit the test mode (See (2) How to exit from the test mode.) (7) How to clear the simple security code (K type only) 1. While the code is requested, press and hold the DISP key and press and hold the VOL Up key for 3 seconds. ("----" disappears.) 2. Enter "KCAR" from the remote control unit. (Same operation as the '98 model) Press numeric key 5 twice then press the Track Up key. (This enters "K".) Press numeric key 2 three times then press the Track Up key. (This enters "A".) Press numeric key 2 once then press the Track Up key. (This enters "A".) Press numeric key 7 twice then press the Track Up key. (This enters "R".) 3. The security is canceled and the unit enters the TUNER mode. (8) Other The DNPP/SBF key of the remote control unit (RC510) functions as the menu mode ON/OFF key. The OPEN/CLOSE key of the remote control unit (RC510) functions as the audio adjustment mode ON/ OFF key. The menu is displayed by displaying only the required features. Message such as "CODE OFF" is not displayed when power is turned ON. The contrast can be adjusted only to 0/5/10 using the Up/Down keys.

While holding the FM and Preset 6 keys simultaneously, reset the unit. All indicators and display segments are ON at the start of test mode. (2) How to exit from the test mode Reset the unit. (Note) The test mode cannot be canceled by turning Acc OFF, power OFF or momentary power down. (3) Test mode specifications of the CD receiver Each press of the Track Up key jumps to the following tracks. No. 9 No. 15 No. 10 No. 11 No. 12 No. 13 No. 14No. 9 (return to beginning) Pressing the Track Down key jumps to the previous track to the track being played. (4) Audio The volume is -10 dB (displayed as 30). LOUD is OFF, and CRSC is also OFF whether the function is provided or not. With the Bass/Treble and Balance/Fader controls, pressing the Up/Down key switch the setting alternately to: Full Boost Full Cut Full Boost, Full Right Full LeftFull Right, or Full Front Full Rear Full Front. With the high-pass filter, pressing the Up key sets it to Through/100 Hz/200 Hz and pressing the Down key sets it to 200 Hz/100 Hz/Through. Other adjustments function in the same way as normal mode. (5) Backup current measurement When the unit is reset (backup turned on) while Acc is OFF or when Acc is turned OFF in test mode, the MUTE terminal goes on in 2 seconds, instead of 1.5 second. (The panel, CD, C and MD mechanisms are not activated at this time.) (6) Security code registration after E2PROM replacement servicing (E/M type only) 1. Enter the test mode. (See (1) How to enter the test mode.) 2. Press the SRC key to set All OFF.

CAUTION : For continued safety, replace safety critical components only with manufacturer's 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.
