To use this adaptor, insert it into the slot on the e-WriterPro. When placing IC into this adaptor, keep the IC pin1 to align with pin1 of this adaptor (marked on the PCB).
The adapter is a consumable. The suggested programming times is 5,000 times. When the adaptor has programmed over 5,000 times, the e-WriterPro will display a warning message. It is recommended to replace a new adaptor to ensure successful programming.
