"Invalid Preset" message on the DM300M-DM475
The message Invalid Preset appears when turning the franking machine on or when loading a preset.
This message appears when the franking machine cannot load the Normal Preset. This is the franking machine's default settings.
The message can relate to a scale issue. It also might occur after a Royal Mail rate change. An example is that Royal Mail no longer use a postal class which you use in a preset..
- Select Quit Presets. You return to the Home screen.
- Remove the scale from the top of the franking machine.
- Replace the scale. Ensure you fit it properly and it is level.
- Press Normal Preset.
If the scale weighs correctly but the error reoccurs the problem may be that one of the settings in the Normal Preset is no longer available. Select a new class and re-save the Normal Preset.
