Hasselblad H4D200MS , B, A C

 SENSOR UNIT – INTRODUCTIO N

The captured image is temporarily stored internally on a CF

card in the sensor unit or onto a computer hard disk when

tethered using Phocus. True to the modular design, the sen-

sor unit can be removed and attached to a large format /

view camera (see later section in this manual) for both teth-

ered and untethered use.

When attaching and removing the sensor unit, pay particu-

lar attention to the sensor area. The sensor itself is covered

and protected by a glass IR ﬁlter but take great care when

handling.

If you scratch or mark the ﬁlter in any way, it will show up on

every shot. Replacements are expensive so treat the glass

surface with at least as much care as you would a lens. The

sensor itself is not accessible for any kind of cleaning or

maintenance by a user. Do not attempt any such action as

you will almost certainly damage it irreparably. When stor-

ing separated from the camera, always ensure you use a pro-

tective cover.

As is the case with all electronic devices pay extra care when

working in damp en vironments and avoid damp conditions

for storage.

With untethered use, the management of captures is

handled by the sensor unit. In tethered use, captures are

handled and stored by the computer and can be visually

checked in Phocus immediately.

Settings are made entering the sensor unit menu using the

buttons on the unit. Grip scroll wheels can also be used, if

selected as a function option. Some sensor unit information

is also visible on the grip display, the viewﬁnder display and,

when tethered, Phocus.

Remember to check settings before each shoot. It is easy to

forget small adjustments you might have made the time be-

fore. You might want to consider using the proﬁle function

to make a one-button-press resetting of important func-

tions for your particular regular situations.

 CARE AND MAINTENANCE OF SENSOR

UNIT

• Always replace the protective CCD/lter cover when

the sensor unit is not mounted on a camera.

• Do not touch the exposed CCD/lter with your ngers.

• Keep all foreign objects away from the camera ope n-

ing when attaching or removing a sensor unit.

• Store the sensor unit away f rom moisture and exces-

sive heat.

• Protect the sensor unit from impact.

Note

Time & Date settings on the sensor unit (which are in-

cluded with ﬁles and folder labels) are updated auto-

matically through a FireWire/Phocus connection. These

settings are retained for about two consecutive weeks

by a small rechargeable cell that is automatically re-

charged 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.

 REMOVING AND ATTACHING THE

SENSOR UNIT

1. Remove a FireWire cable if connected.

2. While pushing the safety catch towards the rear of the

camera A, rotate the sensor unit release button to the

right B, and while maintaining that position press the

centre of the button ﬁrmly inwards towards the camera

body C to ﬁnally release the magazine.

3. Clean the outside surface of IR ﬁlter by using clean

compressed air (see warning above ﬁrst). If this is not

enough, then use one of the procedures outlined below.

5. Reattach the sensor unit to the camera immediately

after cleaning to check results.

6. If you still see spots on your shots after you have cleaned

the outside of the infrared ﬁlter, then you may have dust

either on the inside of the IR ﬁlter or on the CCD itself.
