MZ-R909 SECTION 5 ELECTRICAL ADJUSTMENTS
In this set, automatic adjustment of CD and MO can be performed by entering the test mode (see page 12). However, before starting automatic adjustment, the memory clear, power supply adjustment, and laser power check must be performed in the manual mode. A key having no particular description in the text, indicates a set key. For the LCD display, the LCD on the remote commander is shown, but the contents of LCD display on the set are same. Setting method of NV reset 1. Select the manual mode of the test mode, and set item number 021 NV Reset (see page 13).

021 ResNV CC

2. Press the X key.
Precautions for Adjustment
1. Adjustment must be done in the test mode only. After adjusting, release the test mode. 2. Use the following tools and measuring instruments. Test CD disc TDYS-1 (Part No. : 4-963-646-01) SONY MO disc available on the market Digital voltmeter Laser power meter LPM-8001 (Part No. : J-2501-046-A) Thermometer (using the Temperature Correction) 3.
