ADJUSTMENT
3-2. Adjust Mode
Press ADJUST to enter Adjust Mode.
To exit Adjust Mode press ADJUST twice (one press will request confirmation that you wish

3-3. Saving adjustments
Pressing WRITING will exit Adjust Mode and save any adjustments made to non-volatile
memory.
3-4. Adjustment parameters
All parameters except ‘Layout’ can be adjusted using the ▲ ▼ ◄ ► buttons.
‘Layout’ position is adjusted using the ٨ ٧ < > buttons.
3-5. Internal Test Pattern
Test Patterns can be accessed by pressing TEST.P in Adjust Mode.
Continuously pressing TEST.P button will cycle through the available patterns or individual
patterns can be selected by entering the relevant two digit number.
3-6. White Balance adjustment
There are three independent memories for white balance adjustments, press WB in NORMAL
mode to select the desired memory (WB1, WB2, WB3) before making adjustments.
There are two stages for white balance adjustment to allow adjustment of low-level and
high-level portions of the image.
For low-level adjustment 10-20% IRE signal is required and this should be provided by the
main source to be used (i.e. if video is the main source a video test pattern generator should be
used and if computer is the main source test pattern software should be used).
BRIGHTNESS will control the overall brightness of the image (not available for DIGITAL
input) and CUTOFF followed by ADJ.R, ADJ.G and ADJ.B can be used to adjust the relative
intensities of red, green and blue.
For high-level adjustment 70-80-90% IRE signal is required.
CONTRAST will control the overall level of the image (not available for DIGITAL input) and
DRIVE followed by ADJ.R, ADJ.G and ADJ.B can be used to adjust the relative intensities of
red, green and blue.
3-7. Gain and Off-Set
The above adjustments act on the digital signal (after the A/D converter) and assume a signal
level of 0.7V p-p.
It is also possible to adjust the analogue signal (before the A/D converter) but these
adjustments should be kept to the default values in most cases.
OFFSET followed by ADJ.R, ADJ.G and ADJ.B can be used for the low-level adjustment and
GAIN followed by ADJ.R, ADJ.G and ADJ.B for the high-level adjustment.
