Question	Pro-Tips
How do I know if the battery is low?	At 20% battery level, the lock will play a voice prompt (“Low battery, please charge”) and display a red battery icon in the app. We strongly recommend recharging the battery at the first low-battery alert to ensure uninterrupted operation and avoid emergency situations.
What if the battery dies while I'm outside?	Method 1: Plug a power bank into the Emergency Port (USB-C or Micro-USB) at the bottom of the front panel. Method 2: Use the Mechanical Key. Note: NEVER keep the mechanical key inside the house. You may keep one in your car, one at your office, or one with a trusted neighbor for emergency.
What if the battery dies while I'm outside? (Aku Series)	If only Aku (outdoor unit) is out of battery: Method 1: Use the app to unlock Aku Inside (indoor unit). Note: This function works via Bluetooth, so please make sure you are near the lock. Method 2: Connect a power bank to the Emergency Port (USB-C or Micro-USB) located at the bottom of the device. Then press the Reset button to restart the device. If Aku Inside (indoor unit) is out of battery: Use the Mechanical Key to unlock the door. Note: NEVER keep the mechanical key inside the house. You may keep one in your car, one at your office, or one with a trusted neighbor for emergency.
How long does it take to charge?	It varies from devices. In general, a full charge takes approximately 6 hours. The LED on the battery turns from Red to Green when finished.
Can I charge the lock through the front port?	No. The front port is for emergency jump-starts only. To charge the lock, you must remove the battery and charge it using the internal charging port.
How long will one charge last?	On average, 3-12 months depends on different models and usage conditions. [Pro-Tip] Turning off "Pre-load Video" or reducing the "Motion Detection" sensitivity in the App can significantly extend battery life.
