At end of line, the next behavior of a display area depends on the current cursor position, character size and display mode. Display area behaviors for some magnified character sizes are as follows: Regular size (1×1) characters (Over-write mode) Right Most Column Lower Most Row Current Cursor Position The next cursor position is here. 1×2 Magnified characters (Over-write mode) Right Most Column Current Cursor Position Lower Most Row The next cursor position is here. - 15 - CU24063-Y100 1×2 Magnified characters (Over-write mode) Right Most Column The next cursor position is here.

This command is valid for characters written after this command execution; it does not affect characters that are already displayed. Note: This individual character brightness is a relative value of allover display brightness. If the display brightness level and the individual matrix brightness level are 200% (2,000 cd/m2) and Level 5 (57%) respectively, the individual character brightness is 2,000 2 2 cd/m × 57% = 1,140 cd/m . In order to set allover the display brightness, please refer to the command “13.3.35 Brightness level setting”.

[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 30～100 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.
