VFD-modules, please adhere to governmental related laws or regulations.
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.
Avoid touching conductive electrical parts, because the VFD-module uses high voltage exceeding 30～100 volts.
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.
VFD-modules needs electrostatic free packaging and protection from electrostatic charges during handling and
usage.
During operation, VFD and VFD-modules generate heat. Please consider sufficient heat radiation dissipation using
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.
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,
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.
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.
Please use VFD-modules under the recommended specified environmental conditions. Salty, sulfur and dusty
Some VFDs contain a small amount of cadmium in the phosphor and lead in the solder. When discarding VFDs or
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
heat sink solutions.
we recommend using a sufficient power capability and quick starting of the power regulator.
unauthorized reconstructed VFD-modules.
Even when electric power is turned off, it may take more than one minute for the electrical current to discharge.
environments may damage the VFD-module even during storage.
