• For any outage, the fully-charged controller could keep working for sending alarm
for 24h. For initial start of freezer or after a long time of outage, you should fi rstly
charge the battery fully, and keep the freezer under operation for continuous 12h.
• When the sensor fails, the system will enter into a self-protecting operation status,
the refrigerating system will automatically run for 8min by default, and then cease
for 9min, which will become a cycle operation until the fault is eliminated.
• For the function above mentioned, some differences might appear on different
models, so please subject to the machine you have bought.
