If a bypass mode is being used at the par-
ticular system (as a rule, this is the emer-
gency mode), the brightness / contrast
values for this mode must be adapted to
the “Normal mode”.
This is done in the SSW under:
=> Adjustment => Video amplifier => By-
pass
- Insert the TV dynamic test.
In the “Normal mode”, measure the lumi-
nous intensity values in the 2L and 5R
fields using the Mavo monitor and make
a note of the values.
- In the “Bypass mode”, use the slider for
Maximum background to set the value in
the 5R field and the slider for Maximum
contrast to set the value in the 2L field to
the values that were noted.
- If necessary, repeat both adjustments.
