Important notes:
1. Because of the working conditions of VFD, there is a DC high voltage of about 38V, so don't touch the VFD pins when it is working.
2. Because of the characteristics of VFD, long working brightness will be attenuated, so it will become uneven, is a normal phenomenon.
3. Because the clock module is selected parts, if there is no clock module installed, then the relevant clock function instructions are invalid.
4. When there is no clock function, no signal input and button operation, will enter standby state and display standby characters, in the external port closed setting , after 1 minutes it will close the filament power supply and VFD high voltage. Enter deep standby status. Auto wakeup when there is a signal input or press button operation.
