Need to reset a VeriFone 3750 v501 to its original default state. The program password has been changed and I cannot access to update


Turn off and unplug the Verifone 3750. Wait for five seconds or so and then plug it back in. This will automatically reset the Verifone 3750 and it will reboot and restart.

Reset the shift. Resetting the shift is another reset option available for Omni. Press "Shift," then "#," followed by "1" to reset and change the shift.

Press "Shift," then "#," then "2" to stop a change and keep the shift on the current settings.

The keypad needs to be replaced as the green "Enter" key contact wears out due to repeated use. Common problem with these units. I can replace these cheaply.

Verifone Omni 3750, set up problem


Your processor should be able to essentially blow out the memory on the terminal. From their a dummy program can be loaded to finish wiping out any residual memory. Lastly, you will need to do a completely new core load with your actual file build. The process takes much longer than normal due to the multiple core loads but it is effective. If your processor is not familiar with this or is unable, I would be more than happy to take over your services but am unable to solicit on this site. So, feel free to email me with any questions you may have at CJepson@federal-financial.com. Hope this helps.
