A-02/Deadman's Switch

General Knowledge

The A-02 (also known as the "Deadman's Swtich") shows up when the IBTS Temp is over 160°C and the Bullet has not received a physical input for over 2 minutes. If the Bullet still hasn't received a physical input for a while after A-02 showed up, the Power Settings will be set to P0 to avoid overheating and damage. The purpose is to ensure that the Bullet remains attended when it's hot.

Solution

Though pressing any physical button will clear the A-02, we recommend pressing F1 to avoid making accidental changes, i.e. accidentally going to Cooling Mode by pressing PRS.

Note

Making settings changes through RoasTime will not prevent the A-02 from showing up; the Bullet has to receive a physical input.
