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.
Overview
≥ 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.
Operating precautions
≥ 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.
