Adjusting procedure
» Connect a DC voltmeter to TP4 on the PC I/F unit.
Move the cursor to "Ë+Badj.3.3V" and use "VOL" (+)
and (–) keys to adjust the voltage to 3.30 ± 0.01 V.
» After adjustment to 3.3 V, move the cursor to the
"Ë+Badj.1.8V" line and press the "ENTER" key on
the remote controller. Adjustment will be made
automatically.
If "ERR" appears, adjust the voltage at pin (6) of
CN9 on the PC I/F unit to 1.90 ± 0.01 V.
Adjusting procedure
1.Set the colour system to PAL.
2.Select the PAL source.
» Split colour bar signal (100% white, colour 100%
modulation)
» With the video output open, make sure the voltage
is 2.0Vp-p (between sync level and 100% white
level).
» If the voltage is not as specified, readjust the signal
generator.
Provide the above RF signal to ANT and adjust
"TUNER A DAC ADJ" so that the tuner output is
1.0 ± 0.02 Vp-p at TP1101.
