11 JIG FOR CHECKING BD (MD) BO ARD W A VEFORM The special jig (J-2501-149-A) is useful for checking the waveform of the BD (MD) board. The names of terminals and the checking items to be performed are shown as follows.
12 IOP DA T A RECORDING AND DISPLA Y WHEN OPTICAL PICK-UP AND NON-V OLA TILE MEMOR Y (IC171 OF BD (MD) BO ARD) ARE REPLA CED The IOP value labeled on the optical pick-up can be recorded in the non-volatile memory . By recording the value, it will eliminate the need to look at the value on the label of the optical pick-up.
13 • 0.9 mW power Specified value : 0.84 to 0.92 mW • 7.0 mW power Specified value : 6.8 to 7.2 mW lop (at 7mW) • Labeled on the optical pickup Iop value ± 10mA • T raverse waveform Specified.
14 RETR Y CA USE DISPLA Y MODE • In this test mode, the causes for retry of the unit during recording can be displayed on the fluorescent indicator tube. During playback, the “track mode” for obtaining track information will be set. This is useful for locating the faulty part of the unit.
