Table 5-22 Focus check commands
Visual check on the laser,when Focus control ON, if the
laserlight is visible.
Once the check is completed,switch the focus control OFF
before executing next command.
To check the waveform of FOCUS- and FOCUS+,
connect a 10W / 0.25W resistor between FOCUS- and
FOCUS+ to serve as dummy load without connecting the
loader.

Play DVD Test Disc.
Measure outputs of diodes A, B, C, D, E, F.
Table 5-24
At outputs of diodes A, B, C, D the following waveform can be
measured: Refer to Figure Output of diodes A, B, C, D
Figure 5-34 Output of diodes A,B,C,D
Check the HF output, RFO, at testland F219 and observe the
waveform, refer to Figure RFO.
