General sensor unit care
•
Time & Date settings on the sensor unit (which are included with files and batch labels) are updated automatically through a
FireWire/Phocus connection. These settings are retained for about two consecutive weeks by a small rechargeable cell that is auto-
matically recharged by the main battery or FireWire with regular use. If problems occur, charge the cell by leaving the sensor unit
turned ON for around 12 hours.
•
Do not touch the exposed CCD/filter with your fingers.
•
Always replace the protective CCD/filter cover when the sensor unit is not mounted on a camera.
•
Never attempt to remove the glass filter from the front of the CCD–you will probably ruin the CCD if you do so. If dust manages to
get between the IR filter and CCD, it can only be removed at the Hasselblad factory. Contact your Hasselblad dealer for assistance.
•
Store the sensor unit away from moisture and excessive heat.
•
When cleaning the filter, take at least as much care as you would with any optic. See under
Appendix
for cleaning instructions.
Approval / (OK) button
F
This button steps through the three approval levels,
thereby assigning an approval status to the image
currently displayed (or selected) in the preview screen.
(part of the Instant Approval Architecture system). Also acts as a con-
firmation button (OK button) for various menu operations, such as de-
leting images; indicated by a label beside the button on the preview
screen.
Busy-light
G
Flashes to indicate that the sensor unit is performing an operation
(such as saving a new capture). Although a new capture cannot be
made while the light is flashing, focusing, aperture and shutter speed
settings can all be changed.
Red signifies a problem (an explanatory message will be displayed).
Safety catch
H
Used when removing the sensor unit.
CCD and IR filter
I
The sensor is positioned behind a permanently mounted IR filter.
Always be very careful not to touch or scratch the surface of the filter
when it is exposed.
Replace the protective cover whenever the sensor
unit is not mounted on a camera.
