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 later section in this manual for cleaning

instructions .
