1.5 Using the OCP controls

1.5.1 Button lights

When the OCP is powered its buttons are illuminated. The normal colour of a button is dim
green. The light shines brighter when a button is selected. You can set the illumination levels in
the OCP set-up menu.

1.5.2 Non-standard indication

When a value for one of the video parameters is changed by the user its status will become
'non-standard'. The button for its function group will lit up bright yellow when it is selected and
dim orange when it is not. A changed value is indicated by a *-symbol in the text-display.
All changes are relative to the user's reference settings which are the last stored or recalled
settings. By recalling (full or partial) or storing a scene file all non-standard indications are reset.
You can find more information about file handling in the section 'Using files' of this guide.

Note Note
Analogue values are being regarded as changed when they vary more than 10% of their
reference value.
☞ ☞
Note Note
Functions that are blocked or disabled by another function or that are not part of the current
function set (simple, basic or full) will not be indicated 'non-standard' even if they are changed.

buttons. These type of buttons only operate as long as they are held down. The FILES button
operates both selective and momentary.
