SERVICE ADJUSTMENTS
BEFORE ADJUSTMENTS
1. Ensure that the 120 V AC power is supplied correctly.
2. Warm run the unit and measuring tools sufficiently (at least 30 minutes).
3. Perform all adjustments based on the initial values. There is no problem if the result of an adjustment performed by observing the screen is
different from the initial value.
4. Never attempt to turn on potentiometers or other controls that are not explicitly mentioned in the adjustment procedures.
NOTE: When using the BT-YA701P (NTSC/PAL Video Input Card) in an adjustment, be sure to check the output waveforms from the
video input card in advance.
SETTINGS REQUIRED FOR ADJUSTMENTS
For the functions other than those that should be set before each adjustment, reset them to the initial values
according to the table on page 10 before proceeding to the adjustment.
Correct adjustments will not be possible unless the values of the functions are reset to the initial values.
