 SENSOR UNIT – INTRODUCTION

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 environments­ 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.

 REMOVING AND ATTACHING THE

 

SENSOR UNIT

A

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.

 CAREANDMAINTENANCEOFSENSOR UNIT

Always replace the protective CCD/filter cover when the sensor unit is not mounted on a camera.

Do not touch the exposed CCD/filter with your fingers.

Keep all foreign objects away from the camera open- ing when attaching or removing a sensor unit.

Store the sensor unit away from moisture and exces- sive heat.

Protect the sensor unit from impact.

N o t e

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.
