4. Operating Instructions
Temperature Control:
The cooler features an automatic thermoregulation system. It will cool rapidly upon activation. The system is designed to automatically shut off when the internal temperature reaches 36℉ (2℃) and reactivate when the temperature rises to 46℉ (8℃). This cycle ensures optimal refrigeration and prevents freezing.

- Alarm Setting: Allows setting an alarm, for example, to remind you to take medication after insulin injection.
Low Power Alarm:
When the battery power is low, the cooler will emit intermittent beeps to remind you to charge or replace the battery. The battery can also function as a power bank to charge other electronic devices.
Travel Considerations:
The cooler is designed to be TSA approved for air travel. However, it is always recommended to check with your specific airline regarding their policies for carrying medical devices with lithium batteries before your flight.
5. Maintenance
- Cleaning: Wipe the exterior and interior of the cooler with a soft, damp cloth. Do not use abrasive cleaners or immerse the unit in water.
- Ventilation: Ensure that the ventilation holes are never blocked during operation. Blocking these holes can lead to overheating and damage the cooler.
- Battery Care: Store batteries in a cool, dry place when not in use. Recharge batteries regularly, even if not fully depleted, to maintain their lifespan.
- Storage: When storing the cooler for extended periods, ensure it is clean, dry, and the battery is partially charged (around 50%).
