1. Powering the Units

2. Positioning the Cameras
Place the baby units (cameras) in locations that provide a clear view of your baby. Ensure they are out of reach of children and at least 5-6 feet (1.5-2 meters) away from the baby to avoid buzzing sounds. The cameras can be placed on a tabletop or mounted on a wall or crib using the included screws.
- For optimal signal, lift the ANTENNA on the monitor.
- Avoid placing cameras near other electronic devices that may cause interference.
3. Pairing Cameras (if necessary)
Your cameras should come pre-paired. If you need to add or re-pair a camera:
- Turn on both the parent unit and the camera you wish to pair.
- Access the camera pairing menu on the parent unit (refer to the on-screen menu for specific steps).
- Press the pairing button on the back of the camera unit. The monitor should display the camera's video feed once successfully paired.

VOX Mode (Voice Operated Exchange)
In VOX mode, the monitor screen will automatically turn on when sound is detected from the baby's room, conserving battery life. You can adjust the sensitivity level of the VOX feature in the settings menu.
Lullabies
The monitor includes 8 pre-programmed lullabies to help soothe your baby. Access and control the lullabies through the parent unit's menu.
Room Temperature Monitoring
The camera unit features a temperature sensor that displays the room temperature on the parent unit. You can set alerts for temperature deviations. Note that the camera itself may generate some heat, leading to a slightly warmer reading (2-4°F / 1-2°C higher) than the actual room temperature.
Night Vision
The cameras are equipped with advanced infrared night vision, automatically activating in low-light conditions to provide a clear black-and-white image of your baby, even in complete darkness.

Feeding Time Reminders
Set customizable feeding time reminders on the parent unit to help maintain your baby's feeding schedule.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your baby monitor:
- Cleaning: Use a soft, dry cloth to clean the monitor and camera units. Do not use abrasive cleaners or solvents.
- Battery Care: For the parent unit, avoid extreme temperatures. If storing for a long period, charge the battery to about 50% and store in a cool, dry place.
