Customers keep complaining that they do not see machines, cannot start machines or just keep being told to wait. What do I do?

This is due to poor cellular service. Check with your Greenwald sales rep for a solution.

Setup is not working. What do I do?

Confirm you have the correct kit for the machine, use model lookup if necessary. Make sure profiles are setup correctly.

Machine models do not match what was supposed to have been setup for the location. What do I do?

Double check the setup in GMS corresponds to make sure machine type is correct for the location. Machines may have been changed in between setup and install.

Devices will not accept programming. What do I do?

This is due to poor cellular service. Program Greenwald pay device in your shop or in an area that has better cell service.

I am getting an “07 error”. What does that mean?

This is a serial communication error. Make sure dip switch #3 is turned ON, then cycle power to the machine to establish communication.
