Maintenance of rechargeable batteries: In order to prolong the battery life, please avoid idling the product. It is better to run the product more than 24 hours
monthly to recharge.
Battery Maintenance
A. If you are not using the freezer for long periods of time, you should plug in the unit once a month and turn on the power. Let the battery recharge for at
least 24 hours before turning back off and unplugging.
B. If the power supply is interrupted, you should switch the unit off. Failure to do so can cause the battery to lose power and possibly have permanent
damage.
C. The life of the battery is about 2 to 3 years. If you near the end of the battery life or if it is not properly used, the low battery alarm will sound. This will not
affect the usage of the freezer but can cause alarm failure and problems with printing functions. Contact after-sales service staff to replace the battery.

Annex2: Installing the printer paper for the optional printer
Automatic printing:
When the printing interval Pt is not 0, the printer prints the current data every Pt minutes.
Note: When the printing interval Pt is less than the recording interval SCy, it is printed according to the recording interval; the remaining printing intervals are
printed as an integral multiple of the recording interval Scy, that is: the printing interval Pt should be set as an integral multiple of the recording interval.
Manual printing:
When the key is unlocked and the working voltage is normal, press the print key to display "P01" by the digital tube, press the up key or down key to adjust
"P00~P07." Press the set/mute multiplexing key or print key, and the printer will cancel the manual printing (P00) or print the data recorded in the previous
days (1 ~ 7), with the data interval same as the automatic printing interval.
Printer Paper:
The printing paper comes pre-installed. When the printer is out of paper, you can replace it
with the same type of paper. The installation steps are as follows:
1. Press the cylinder button on the printer and open the cover of the printer.
