10.2.2 Safety Protection Reagent
The top priority is to protect the tissue samples in the current running program and to
prevent the tissue samples from being damaged due to environmental changes. In the
event of failure or device failure, the system will proceed according to the following
process:

If a fault occurs, local and remote alarms will be issued.

The alarm information reminds the user to remove the samples. If the samples
are not removed after 5 minutes, the system will fill the dehydration cylinder
with the safety reagent to ensure the safety of the samples.

If the safety reagent filling process cannot be completed, it may be due to
insufficient safety reagents, blocked flow channels or system leakage. At this
point, the dehydration cylinder lid can be opened to check the liquid level of
the reagent in the cylinder. If the liquid level is insufficient, the dehydration
cylinder shall be turned off to empty the reagent. Add safety reagents to the
appropriate amount of liquid.

In case of power failure, the dehydration cylinder lid shall be opened to
remove tissues through manual unlocking mechanism. If power recovered, the
system will reheat according to previous settings, and extract appropriate
safety reagents to fill the dehydration cylinder to ensure the samples safety.

10.2.3 Electronic Lock
The electronic lock is controlled by software. If the opening and closing function fails,
manual operation can be performed in the following manners:

Open the active carbon door under the marble platform. You can see the manual knob of
the electronic lock. Rotate the manual knob clockwise for approximately 150 turns until
it can no longer be rotated. The electronic lock can be unlocked.

After closing the dehydration cylinder lid, rotate the manual knob counterclockwise for
approximately 150 turns until it can no longer be rotated. The electronic lock can be
locked.
