Overview

The model AK-HBU931P is a build-up unit which is designed for use with the AK-HC931P multi-format camera. When installed in the multi-format camera, it enables a large lens to be mounted, thus yielding the same range of operations as that afforded by a larger camera.

Operating precautions

≥Be absolutely sure to supply the build-up unit’s power from the multi-format camera.

≥Handle the viewfinder carefully.

Dropping the viewfinder or subjecting it to strong impact may cause malfunctioning and/or accidents.

≥Operate the unit within a temperature range of 32oF to 104oF (0oC to + 40oC). Operation in locations below 32oF or above 104oF may adversely affect the internal parts.

≥Be absolutely sure to turn off the power before connecting or disconnecting the cables.

≥Do not use the unit outdoors.

≥Install the unit at a distance of at least 3.3 ft (1 meter) from the monitor.

≥Maintenance

Disconnect the optical fiber cable plug, and wipe the unitr with a dry cloth. To remove stubborn dirt, soak a cloth in diluted kitchen detergent and wring it out well, and then wipe the unit gently.

Caution

≥Avoid using benzine, paint thinners or other volatile substances.

≥If a chemically treated cloth is to be used, read the precautions for its use carefully.
