13 MZ-N1 Operation in Setting the T est Mode • When the test mode becomes active, f irst the display check mode is selected. • Other mode can be selected from the display check mode. • When the test mode is set, the LCD repeats the following dis- play .
14 MZ-N1 Configuration of T est Mode Manual Mode Mode to adjust or check the operation of the set by function. Normally , the adjustment in this mode is not executed. Ho wev er, the Manual mode is used to clear the memor y , power supply adjustment, and laser po wer check before performing automatic adjustments in the Ov erall Adjustment mode.
15 MZ-N1 Self-Diagnosis Result Displa y Mode This set uses the self-diagnostic function system in which if an error occurred during the recording or playing, the mechanism control block and the po wer supply contr ol block in the microcomputer detect it and record its cause as history in the non volatile memory .
16 MZ-N1 • Description of indication history Histor y code number Description 1 The first error N The last error N1 One error before the last. N2 T wo errors before the last. R_ T otal recording time Reset the Err or Display Code After servicing, reset the error display code.
17 MZ-N1 Jog and Ke y Check Mode This set can check if the set and remote commander function nor - mally . • Setting method of jog chec k mode 1. Set the test mode (see page 13). 2. Press the jog button to acti vate the jog check mode and display as below .
18 MZ-N1 Example1: When the > ke y on the set is pressed: Example2: When the N > key on the r emote commander is pressed: 4. When all the keys on the set and on the remote commander are considered as OK, the follo wing displays are shown for 4 sec- onds.
19 MZ-N1 SECTION 5 ELECTRICAL ADJUSTMENTS Outline • In this set, automatic adjustment of CD and MO can be per- formed by entering the test mode. Howe ver , before starting automatic adjustment, the memory clear , po wer supply adjustment, and laser po w er check must be performed in the manual mode.
20 MZ-N1 2. NV adjusted values modifying procedure 1) Select manual mode of the test mode, and set item number 336 (see page 14). 2) Adjust with the [VOLUME +] ke y (adjusted value up) or [VOL- UME - - ] ke y (adjusted value do wn) so that the adjusted value becomes 8.
21 MZ-N1 38) Select manual mode of the test mode, and set item number 873 (see page 14). 39) Adjust with the [VOLUME +] ke y (adjusted value up) or [VOL- UME - - ] ke y (adjusted value do wn) so that the adjusted value becomes BB. 40) Press the X key to write the adjusted value.
22 MZ-N1 25) Select manual mode of the test mode, and set item number 874 (see page 14). 26) Adjust with the [VOLUME +] k ey (adjusted value up) or [VOL- UME - - ] ke y (adjusted value do wn) so that the adjusted value becomes 05. 27) Press the X key to write the adjusted value.
23 MZ-N1 • Adjustment method of Vrec PWM Duty (L) (item number: 766) 1. Connect a digital v oltmeter to the AP611 (VREC) on the MAIN board, and adjust [VOLUME +] ke y (voltage up) or [VOLUME --] ke y (voltage down) so that the v oltage becomes 1.08 V .
24 MZ-N1 10. Press the N key , and set the laser MO write adjustment mode (item number 013). 11. Check that the laser power meter reading is 4.95 ± 0.50 mW . 12. Check that the voltage both ends (TP (+) and TP ( – )) of resis- tor R521 at this time is belo w 80 mV .
25 MZ-N1 Note: Adjust the CD first, when performing adjustment. • Electrical offset adjusting method Caution: The electrical of fset adjustment must be made with no disc loaded. 1. Make sur e that the power supply v oltage is 3 V . 2. Set the test mode (see page 13).
26 MZ-N1 Resume Clear Perform the Resume clear when all adjustments completed. • Resume c lear setting method 1. Select the manual mode of the test mode, and set item number 043 (see page 14). 2. Press the X key. 3. Pr ess the x / CHG key to return to the test mode (display check mode).
27 MZ-N1 Rewriting the P atch Data at Replacement of Main Boar d or Non volatile Memory (IC802) This set requires the patch data in the non volatile memory (IC802) to be re written using the application, when the MAIN board o r non volatile memory (IC802) was replaced.
28 MZ-N1 5. Confirm that the model and version indicated on the title bar coincide with the codes displayed in the De vice Name block and the V ersion block in the window .
MZ-N1 29 29 8. Click the [Usb Disconnect] button. 9. Confirm that the windo w becomes as shown belo w where the [Write + V erify] button and [Read] b utton are inactive. 10. Disconnect the USB cable from the personal computer and the USB cradle. 11. Remov e the set from the USB cradle.
