18、ent for CD. Below is the procedures for this mode. Step 1: Enter into Doctor mode (For more information refer to section 8.1 on key operation to enter into this mode). Step 2 : When 14 key are pressed at the doctor mode, the following shall be displayed for 3 secs. The result shall correspond to the

19、 condition met as shown in the table below : 21 SA-PMX1E / SA-PMX1EB / SA-PMX1EG 8.1.8. TPS Inspection Purpose : Tape for TPS is put into Deck. TPS inspection starts with one key operation. This mode shall run a test program to check REV TPS for the Deck and ends by displaying the result and ejectin

20、g the Deck. Below is the procedures for this mode. Step 1: Enter into Doctor mode (For more information refer to section 8.1 on key operation to enter into this mode). Step 2 : Press button on remote control. Enter into TPS Test mode. (During this mode) Software will start checking for existence of

21、cassette in Deck. If the Deck does not contain any cassette, it shall end the test and displays EEROR. If the cassette is detected, test shall start by playing the DECK in reverse direction for 1 sec and perform REV TPS. If TPS signal is OK, the Deck shall be ejected. Below is information on the TPS

22、 under 3 examples. 1. If ERROR Flag is set ERROR shall be displayed. TPS check result shall not be shown in this case. 2. If Deck TPS check = OK 3.

23、1 : Enter into Doctor mode (For more information refer to section 8.1 on key operation to enter into this mode). Step 2 : Press PROGRAM button on remote control. Execute MP3 Disc Check (Refer Flowchart below) 23 SA-PMX1E / SA-PMX1EB / SA-PMX1EG Result display : Displayed if MP3 test OK Displayed if

24、MP3 test NG 8.1.10. CD Recording Purpose : This test is designed for CD to TAPE recording inspection. Below is the procedures for this mode. Step 1 : Enter into Doctor mode (For more information refer to section 8.1 on key operation to enter into this mode). Step 2 : Press 4 button on remote control

25、. It shall enter CD to TAPE Recording Test. Step 3 : Set shall be set to following condition automatically. VOLUME 50. BASS / TREBLE FLAT (0dB). Preset EQ OFF. H.BASS and surround off. Step 4 : Either set in CD or TAPE mode, CD shall PLAY and TAPE REC for 3 seconds. Step 5 : After 5 seconds, TAPE RE

26、C shall be stop and TAPE REW to starting point (count 0).During TAPE REW, CD drawer shall open Step 6 : Press 5 button on remote control. To start TAPE PLAYBACK to check the recorded signal. When key 5 pressed, TAPE PLAY shall start for 3 seconds to playback the recorded signal. Tape shall be ejecte
