Refer to "Window command group", Page 24. There is no independed display memories for each "Window". There are 2 types of "Window", Base-Window and User-Window . 6.3.1 Base-Window This has the whole display screen and if User-Window is not defined, all display operation is processed under this Base-Window. When some User-Window is defined, the display operation to the out of display screen of User-Window should be processed under Base-Window. When Base-Window is selected even if some User-Window is defined, all of display operation is processed under Base-Window. Therefore, the current display pattern of User-Window is overwritten.

[VFD tubes are made of glass] * Because the edges of the VFD glass-envelop are not smooth, it is necessary to handle carefully to avoid injuries to your hands * Please avoid breaking the VFD glass-envelop to prevent injury from sharp glass particles. * The tip of the exhaust pipe is fragile so avoid shock from impact. It is recommended to allow sufficient open space surrounding the exhaust pipe to avoid possible damage. * Please design the PCB for the VFD-module within 0.3 mm warping tolerance to avoid any forces that may damage * the display due to PCB distortion causing a breakdown of the electrical circuit leading to VFD failure. [High voltage] * Avoid touching conductive electrical parts, because the VFD-module uses high voltage exceeding 30100 volts. * Even when electric power is turned off, it may take more than one minute for the electrical current to discharge. [Cable connection] Do not unplug the power and/or data cables of VFD-modules during operating condition because unrecoverable * damage may result. Sending input signals to the VFD-module during a power off condition sometimes causes I/O port damage. * * It is recommended to use a 30 cm or shorter signal cable to prevent functional failures. [Electrostatic charge] VFD-modules needs electrostatic free packaging and protection from electrostatic charges during handling and * usage. [Structure] * During operation, VFD and VFD-modules generate heat. Please consider sufficient heat radiation dissipation using heat sink solutions. We prefer to use UL grade materials or components in conjunction with VFD-modules. * * Wrap and twist motion causes stress and may break VFDs & VFD modules. Please adhere to allowances within 0.3mm at the point of attachment. [Power] * Apply regulated power to the VFD-module within specified voltages to protect from failures. Because some VFD-modules may consume in rush current equal to twice the typical current at power-on timing, * we recommend using a sufficient power capability and quick starting of the power regulator. * VFD-module needs a specified voltage at the point of connection. Please use an adequate power cable to avoid a decrease in voltage. We also recommend inserting a power fuse for extra protection. [Operating consideration] Illuminating phosphor will decrease in brightness during extended operation. If a fixed pattern illuminates for an * extended period,( several hours), the phosphor efficiency will decrease compared to the non operating phosphor causing a non uniform brightness among pixels. Please consider programming the display patterns to use all phosphor segments evenly. Scrolling may be a consideration for a period of time to refresh the phosphor condition and improve even illumination to the pixels. * We recommend using a signal cable 30cm or less to avoid some possible disturbances to the signal. [Storage and operating environment] Please use VFD-modules under the recommended specified environmental conditions. Salty, sulfur and dusty * environments may damage the VFD-module even during storage. [Discard] * Some VFDs contain a small amount of cadmium in the phosphor and lead in the solder. When discarding VFDs or VFD-modules, please adhere to governmental related laws or regulations. [Others] * Although the VFD-module is designed to be protected from electrical noise, please plan your circuitry to exclude as much noise as possible. * Do not reconstruct or repair the VFD-module without our authorization. We cannot assure the quality or reliability of unauthorized reconstructed VFD-modules. Notice: We do not authorize the use of any patents that may be inherent in these specifications. Neither whole nor partial copying of these specifications are permitted without our approval. If necessary , please ask for assistance from our sales consultant.
