8. WARRANTY
This display module is guaranteed for 1 year after a shipment from Newhaven Display.
9. OPERATING RECOMMENDATION
9-1.
Since VFDs are made of glass material.
Avoid applying excessive shock or vibration beyond the specification for the module.
Careful handing is essential.
9-2.
Applying lower voltage than the specified may cause non activation for selected pixels.
Conversely, higher voltage may cause may non-selected pixel to be activated.
If such a phenomenon is observed, check the voltage level of the power supply.
9-3.
Avoid plugging or unplugging the interface connection with the power on.
9-4. If the start up time of the supply voltage is slow, the controller may not be reset.
The supply voltage must be risen up to the specified voltage level within 30msec.
9-5.
Avoid using the module where excessive noise interference is expected. Noise affects the
interface signal and causes improper operation.
Keep the length of the interface cable less than 50cm (When the longer cable is required,
please contact Newhaven Display engineering).
9-6.
When power supply is turned off, the capacitor does not discharge immediately.
The high voltage applied to the VFD must not contact the controller IC.
(The shorting of the mounted components within 30 seconds after power off may cause
damage.)
9-7. The fuse is mounted on the module as circuit protection.
If the fuse blown, the problem shall be solved first and change the fuse.
9-8.
When fixed pattern is displayed for long time, you may see uneven luminance.
It is recommended to change the display patterns sometimes in order to keep best display
quality.
REMARKS
This specification is subject to change without prior notice in order to improve the design and quality.
