Taken from ATUHM user manual:

[Section 91.2—Firmware Update]
If updated to Firmware Version 4.03, please note that the Emergency Release Switch (ERS) will eject the cockpit canopy and initiate a forced deactivation of ATUHM. This additional feature has been included for increased safety and precautionary measures.

Firmware prior to 4.03 does not include an automated deactivation feature once the ERS is initiated. Ryft Industries strongly suggests updating to Version 4.03 as soon as possible.
