Introduction The BA69W liquid-crystal display is a tailor-made operator display for modern cash-register applications with an embedded scale solution. The BA69W has a 5.7" screen for black/white presentation and is designed with STN technology. The flat screen provides standard VGA compatibility in the 1/4-format of a standard screen. As a result, graphic user interfaces are presented with a high information content that is easily viewed for both customers and operators.
What does VGA/4 mean? VGA/4 means that 1/4 of a full screen is utilized for every display. The illustration shows the arrangement of the VGA quadrants (320x240 picture elements) for the operator and customer displays to the standard for a VGA screen with a resolution of 640x480 picture elements.
About the manual References in the Manual are indicated by this symbol. This symbol is used for cautions and warnings. Cleaning the BA69W During cleaning, be absolutely sure that the cash-register system is shut off, that the power cable has been disconnected, and that no moisture is allowed into the interior of the display. Clean your BA69W at regular intervals with a cleaner which is suitable for plastic surfaces. This cleaner may be ordered from Wincor Nixdorf-Plus.
Recycling the BA69W Environmental protection does not begin when it comes time to dispose of a device; it begins with the manufacturer. The LC-Display BA69W is manufactured without the use of CFCs und CCHS and is produced mainly from reusable components and materials. The processed plastics can, for the most part, be recycled. Even the precious metals can be recovered, thus saving energy und costly raw materials. At this time, there are still some parts that are not reusable.
Before assembling Unpacking and checking the packing list Unpack the parts and check to be sure that the packing list agrees with the specifications on the bill of delivery. If you determine that there is shipping damage or discrepancies between the packing list and the bill of delivery, please inform your contract affiliate or the sales office of Wincor Nixdorf immediately.
