INSTALLATION
The Head offset learning procedure MUST be performed before the 4025TR
will use the KeyKode information it receives. The head offset for each film
type and transfer speed MUST be initialized for each combination used.
The automatic alignment procedure in the 4025TR calculates the exact
offset between the head and the gate, and is normally required only during
installation. Following this procedure should provide a quick, and error free
method of calibrating the 4025TR.
The Setup menu is used to perform manual adjustments or to invoke the
head offset learning procedure. Press the SETUP key to access the Setup
menu. Using the # & $ keys drop down the CONFIG menu. Use the %
& & keys to highlight the KK HEAD OFFSET menu item and press the
SELECT key to show the HEAD OFFSET SUMMARY. The current head
offset numbers and the approximate number of film frames from the head
to the gate are shown for each film type and transfer rate.
The head offset learning is protected from normal user access by the
Engineering Mode DIP switch. With Engineering mode Off, you may look at
the head offset summary page, but cannot proceed to any of the calibration
steps described below. To enable Engineering mode, turn DIP switch #8 on
the 631 module (right hand card inside the 4025TR) to the Closed (On)
position.
Press the % & & keys one or more times to select the head offset you wish
to calibrate. The programmed offset for that film type and transfer rate will
be highlighted. Press the SHIFT + SELECT keys to calibrate the selected
head offset, or press the SELECT key to return to the FILM drop down
menu.
