Replacing the VFD Memory Module
The VFD must have a new program for the intended changes to take place.
1. Remove the VFD cover. Depending on the VFD model, it can be removed in one
of two ways:
• Insert a screwdriver into the notch at the bottom-center of the cover, OR
• Remove the screws securing the cover.
2. With power locked out, remove the old VFD memory module and return it using
these steps:
a) Place latch in Unlock position and pull out gently on the memory module.
b) Follow the instructions on page 2 to return the memory module to MiTek.
c) On the new memory module, push the tab as shown in Figure 3 to extend the
points out, and place the memory module into its slot.
3. Place the latch in Lock position.
