11TEST MODE / ADJUSTMENT How to enter the text modeWhile pressing on 1 and 3 keys, press the RESET key. Starting on the test modeMajor initial positions• When booted with everything off, the test mode starts up.• The valueof the volume is –40dB (indication is 15).• FL lamps all light up.• The diversity is off.• Position: All.• EQ: Flat• COMPRESSOR: OFF• SPE/ANA: PEAK HOLD All display lamps lighting upSince there are many segments on the display section,bridging with other segments can be confirmed. By track up/down keys, grids and segments can be lighted up individu-ally. Opening/Closing Time of the Panel MechanismWhen each time the Angle/Retune button is pressed, timeis displayed after going into the tuner mode. From the maxi-mum angle to return, it takes about 1.2S. CD Mechanism Panel Disk DetectionSensor behavior for detecting whether there is CD disk ornot can be checked. When the sensor is closed off after adisk is inserted, it beeps four times. FM S-Meter Adjustment (Stop Adjustment and others)Method:SG Output: Set to 35dBμ 98.1MHz. (with no modulation)During the above text mode, when Preset 1 and Preset 6.are pressed at the same time, the adjustment begins. Whenadjustments is completed normally, OK is displayed and therewill be one beep of 2kHz. In this case the stop adjustmentvalues will be between 15~25dBμ.When the S-meter value is outside of the standard systemcontrol values, NG is displayed and the initial value of thesystem control is written in the E2PROM. AM Stop AdjustmentMethod:SG Output: Set to 35dBμ 999kHz. (with no modulation)During the above text mode, when Preset 1 and Preset 6.are pressed at the same time, the adjustment begins. Whenadjustments is completed normally, OK is displayed and therewill be one beep of 2kHz. In this case the stop adjustmentvalues will be between 30~43dBμ .When the S-meter value is outside of the standard systemcontrol values, NG is displayed and the initial value of thesystem control is written in the E2PROM. Panel Mechanism AdjustmentThe mechanism detects the open/close position of the paneland writes it to the E2PROM.[ How to enter the test mode ]After entering the above-mentioned test mode, switch overto the tuner mode. Then, press on the TI knob for some timeand the unit will go into panel mechanism test mode, whichis indicated by STAND-BY display.Method:Each time Open/Close key (*key) of the remote controlleris pressed, full-open and full-close positions are registered.(There will be OPEN ENTRY/ CLOSE ENTRY display andthree beeps are sound.)Releasing:When TI key is pressed, the unit goes back to the previoustest mode. Pressing the reset key will take the unit to theinitial condition. DOLBY AdjustmentUsing the extension cord (W05-0755-00), separate themechanism from the unit. Play the TCC-130 and adjust thetest round value to 300mV with the VR1, 2 on the X30 Board.(Refer to the PC BOARD.) Balance with FWD and REV. Releasing the Security CodeThe unit will go into release mode when Preset 6 is pressedwhile Preset 1 is being pressed. The character “C” is dis-played at the right end of the character display. At this point,input KCAR by using 1, 2, 3, and 4 key of the remote control-ler. Confirm with PLAY/PAUSE key and the security code willbe released. Specifications for the Amplifier Control TerminalThe bass boost function of the amplifier can be remotecontrol from the unit. This is a one-way communication, us-ing one control line. The control is made with pulse widths ofthe three kinds of communication data. Five cycle pulses aregenerated from the unit side and when there are three con-secutive successes, communication is established. The pulsewidths are as shown below and the cycle is 200ms.HI: 100msLOW: 70msOFF: 40ms11DPX-5010
