5. Setup
5.1. Powering the Units
Both units can be powered by either the included AC adapter (baby unit) or micro-USB cable (parent unit for rechargeable batteries) or by AAA batteries (not included).

- Parent Unit: Insert 4 AAA batteries (not included) into the battery compartment. If using rechargeable AAA batteries, you can connect the micro-USB charging cable to the parent unit and a USB power source (e.g., a phone charger, not included) to charge them.
5.2. Placement

5.3. Channel Selection
Both the baby unit and parent unit have a channel selector switch. Ensure both units are set to the same channel (1 or 2) to establish a connection. If you experience interference, try switching both units to the other channel.
6. Operating Instructions
6.1. Turning On/Off

6.2. Volume Adjustment
Use the volume control buttons on the parent unit to adjust the listening volume to your preference.
6.3. VOX Mode vs. Continuous Mode
- VOX Mode (Voice Activated): In this mode, the parent unit will only activate and transmit sound when the baby unit detects noise above a certain threshold. This helps conserve battery life.

Toggle the switch on the parent unit to select your desired monitoring mode.

The low battery indicator on the parent unit will illuminate when the batteries are running low, signaling that they need to be replaced or recharged.
6.7. Vibration Alert
The parent unit features a vibration alert, which can be useful in noisy environments or when you prefer a silent notification of your baby's sounds.
7. Maintenance
7.1. Cleaning
Wipe the units with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure the units are completely dry before use.
7.2. Battery Replacement
When the low battery indicator appears, replace the AAA batteries in both units. If using rechargeable batteries in the parent unit, connect the micro-USB cable to recharge them.
8. Troubleshooting
If you encounter issues with your baby monitor, please refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No sound from parent unit | Units not powered on; volume too low; out of range; different channels selected. | Ensure both units are ON. Increase volume. Move parent unit closer to baby unit. Set both units to the same channel. |
| Interference or poor sound quality | Other electronic devices nearby; different channels selected; environmental factors. | Try switching both units to the other channel. Move units away from other electronics (Wi-Fi routers, cordless phones). |
| Short operating range | Obstacles (walls, furniture); environmental interference. | Reduce obstacles between units. Ensure units are within the specified 300m range (open space). |
| Batteries drain quickly | Continuous mode usage; old/low-quality batteries. | Use VOX mode to conserve battery. Replace with new, high-quality AAA batteries. Consider rechargeable AAA batteries for the parent unit. |
| Night light not working | Baby unit not powered on; night light button not pressed. | Ensure baby unit is powered on. Press the night light button. |
