At the bottom, there is a button labeled 'Reset to factory settings' that, when pressed, will reset the roaster's settings to their original default state as configured at the factory.
Resetting to factory setting
2 Factory Reset: At the bottom of the "About this Roaster” screen, there is a 'Reset to factory settings' button. When you select this button, you will be prompted to confirm your action.
1 Confirmation Prompt: A new window will appear, asking, "Are you sure you want to reset this roaster to factory settings?" It warns that this action is not reversible and that resetting to factory settings will delete all local roaster history, roast profiles, roast logs, and the roaster will be unregistered from the associated account.
2 Confirm or Cancel: If you decide to proceed, you can select 'Confirm reset to factory settings'. If you choose not to proceed, you can select 'Cancel' to return to the previous screen without making any changes.
Once the user confirms to reset the roaster to the factory setting the roaster will purge all local data and unregister the roaster. The user will be navigated to the initial screen of the roaster unboxing experience. The user can follow the unboxing instructions on the screen and re-register the roaster.
Important Notes:
Resetting the roaster to factory setting is not reversible and cannot be undone.
Before performing a factory reset, it is recommended to back up any important data associated with your roaster as this process will erase all data from the device.
Ensure that the factory reset is necessary, as it will require you to reconfigure the roaster and potentially reinstall software updates.
Maintenance and cleaning
This screen is divided into three main sections: Cleaning, Self help, and Maintenance
Cleaning:
Machine Lockout Warning: A notification states that the machine will be locked out if the number of completed roasts reaches the maintenance limit. This serves as a reminder to perform regular maintenance to prevent automatic lockout.
Cleaning Instructions: Instructions are provided to empty the Chaff Can, Water Reservoir, and clean the Pre-filter, which are part of the routine cleaning procedure.
Roast Counter: A progress bar indicates the number of roasts completed since the last cleaning. In this case, it shows '0 / 6 Roasts', suggesting that no roasts have been done since the counter was last reset or since the last cleaning.
Start Cleaning Button: A button labeled 'Start cleaning' is present, which begins the cleaning cycle once pressed.
Self Help:
This section includes the following controls.
Empty Hopper: To empty all beans from the hopper.
Empty Drum: To empty the roasting drum of any remaining beans.
Empty Cooler: To clear out the bean cooler.
The 'Self Help' section is intended to assist users in performing maintenance tasks independently, without navigating through multiple menus.
