Power down the unit and with your right hand hold down the 1 5 9 and enter keys down. While those keys are pressed down with your left hand turn on unit it should take you to that nos loader menu. Once in the nos loader menu choose back to NOS password is 1947. Once in the NOS menu choose number 6 Service Menu

More than likely the password is your Merchant ID # if not more than likely is you would have to purchase a new one, mainly because most of the machines have been updated by frimware or baud rate which may prevent normal usage to credit card companies.

System Password not working.

Hi cbeyer286,

First off.. please make sure you post your questions to the proper forum for your model terminal - your question will receive an answer much more quickly. :)

These machines aren't like a laptop where you can reload the OS onto them if they get messed up. The base software is loaded on ROM internally, so you can always wipe the terminal and start from scratch. Companies (like yours) can then build application specific files to load into them.

Here is the standard way of accessing the programming-level menu which will allow you to wipe the memory and enter the proper download parameters for the file you want to load.

  1. Press the F2 and F4 keys at the same time.
  2. You will see a prompt for "system password"
  3. Press: 1,alpha, alpha, 6, 6, 8, 3, 1, Enter
This will bring you to the system menu. From here you can scroll down to System Menu Screen #2 where you can Clear RAM and flash the RAM files. From there your company can treat the terminal as a blank slate ready to program.

Good Luck!

Verifone omni 3750 ethernet problems...

chances are you would need to RAM FILES, FLASH FILES, DEFRAG FILES....this is like resetting and crashing the terminal, starting all over again.

Try this, press F2 & F4 together you should be on GO VARIABLES, enter password 1 alpha alpha 66831 use the down arrow locate RAM FILES, CLEAR ALL GROUPS, CONFIRM, FLASH FILES, CLEAR ALL GROUPS, CONFIRM, then DEFRAG, ALL GROUPS, CONFIRM

Plug in your DSL or cable line (the one you are using) locate the DOWNLOAD, do a FULL
this should pickup your new IP address and make sure you are on COMM SERVER not on DIAL
(dial is only for analog phone line)

We found that it was neither the thermal paper roll nor the thermal component. The cover did not close tight enough and that caused the print-put to be light or missing printed areas.
