19 MZ-B100 SECTION 5 ELECTRICAL ADJUSTMENTS [Outline] • In this set, automatic adjustment of CD and MO can be per- formed by entering the test mode. (See page 12) However , before starting automatic adjustment, the memory clear , power adjustment and temperature adjustment must be performed in the manual mode.
20 MZ-B100 • Adjustment method of VC PWM Duty (L) (mode number: 762) 1. Select the manual mode of the test mode, and set the mode number 762. (See page 13) 2. Connect a digital voltmeter to the AP913 (VC) on the MAIN board, and adjust [EASY SEARCH +] key (voltage up) or [EASY SEARCH - -] key (voltage down) so that the voltage becomes 2.
21 MZ-B100 • Adjustment method of VC PWM Duty (H) (mode number: 765) 1. Select the manual mode of the test mode, and set the mode number 765. (See page 13) 2. Connect a digital voltmeter to the AP913 (VC) on the MAIN board, and adjust [EASY SEARCH +] key (voltage up) or [EASY SEARCH - -] key (voltage down) so that the voltage becomes 2.
22 MZ-B100 [T emperature Correction] • Adjustment Method of temperature correction 1. Select the manual mode of test mode, and set the mode num- ber 014. (See page 13) 2. Measure the ambient temperature. 3. Adjust with [EASY SEARCH +] , [EASY SEARCH - -] key so that the adjusted value (hexadecimal value) becomes the am- bient temperature.
23 MZ-B100 14. When both CD and MO overall adjustments are OK, set the mode No. 043 (Resume) and clear the clock data. r Press the X key , historical data clear Note: In step 10, set the clock data to 99Y11M11D11H11M00S, and in step 14, do not set the clock.
