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.

Info

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