3.1 Charging the Parent Unit
The Parent Unit contains a rechargeable lithium-ion battery. Before first use, fully charge the Parent Unit for approximately 8 hours. Connect one of the provided USB Type-C charging cables to the Parent Unit's Type-C port and the other end to a power adapter, then plug into a wall outlet. The battery indicator on the LCD screen will show charging status.

Connect the second USB Type-C charging cable to the Baby Unit's Type-C port and the other end to a power adapter, then plug into a wall outlet. Ensure the Baby Unit is placed within a safe distance from the baby, out of reach, and away from any potential hazards.

5. Maintenance
5.1 Cleaning
Wipe both units with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure units are unplugged before cleaning.

To prolong battery life, avoid fully discharging the Parent Unit frequently. Recharge the unit when the low battery indicator appears. If storing the unit for an extended period, charge it periodically to maintain battery health.
6. Troubleshooting
- Units not connecting: Ensure both the Parent and Baby Units are powered on and within range. Obstructions like thick walls or other electronic devices can interfere with the signal. Try moving the units closer together or to a different location. Restart both units.
- No sound from Parent Unit: Check the volume level on the Parent Unit. Ensure the Baby Unit is powered on and placed correctly to pick up sounds.
- Poor sound quality: Ensure both units are not too close to other electronic devices that might cause interference. Adjust the position of the Baby Unit relative to the sound source.
- Parent Unit battery drains quickly: Ensure the battery is fully charged. Battery life can be affected by continuous use of features like talk-back or high volume.
- Temperature alarm sounds frequently: Verify the room temperature displayed on the Parent Unit. If the temperature is consistently outside the 16℃-30℃ range, adjust the room's climate or reposition the Baby Unit away from direct heat sources or drafts.
