LOUD is OFF, and CRSC is also OFF whether the func-tion is provided or not. With the Bass/Treble and Balance/Fader controls,pressing the Up/Down key switch the setting alter-nately to:Full Boost Full Cut Full Boost, Full Right Full Left Full Right, or Full Front Full Rear Full Front. With the high-pass filter, pressing the Up key sets itto Through/100 Hz/200 Hz and pressing the Down keysets it to 200 Hz/100 Hz/Through. Other adjustments function in the same way as nor-mal mode.(5) Backup current measurementWhen the unit is reset (backup turned on) while Acc isOFF or when Acc is turned OFF in test mode, the MUTEterminal goes on in 2 seconds, instead of 1.5 second.(The panel, CD, C and MD mechanisms are not acti-vated at this time.)(6) Security code registration after E2PROM replacementservicing (E/M type only)1. Enter the test mode. (See (1) How to enter the testmode.)2. Press the SRC key to set All OFF.3. Press and hold the AUDIO key for 1 second to entermenu 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 4keys.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 todisplay “APPROVED“.8. Quit the test mode (See (2) How to exit from the testmode.)(7) How to clear the simple security code (K type only)1. While the code is requested, press and hold the DISPkey and press and hold the VOL Up key for 3 sec-onds.(“.“disappears.)2. Enter “KCAR” from the remote control unit. (Sameoperation as the '98 model) Press numeric key 5 twice then press the Track Upkey. (This enters “K“.) Press numeric key 2 three times then press the TrackUp key. (This enters “A“.) Press numeric key 2 once then press the Track Upkey. (This enters “A“.) Press numeric key 7 twice then press the Track Upkey. (This enters “A“.)3. The security is canceled and the unit enters theTUNER mode.(8) Other The DNPP/SBF key of the remote control unit (RC-510) functions as the menu mode ON/OFF key. The OPEN/CLOSE key of the remote control unit (RC-510) functions as the audio adjustment mode ON/OFF key. The menu is displayed by displaying only the requiredfeatures. Message such as “CODE OFF“ is not displayed whenpower is turned ON. The contrast can be adjusted only to 0/5/10 using theUp/Down keys.KDC-5016,515S9ATTENTIONAssembly of FPC(Flexible PC board) onto Roller assyTurn Roller assy by 4 times.Hook the end of Roller assy to the tongue.Insert the FPC into the slit of Roller assy then release the end of Roller assy and the tongue.tongueTurn 4 times.End of Roller
