Setup: Insert the rechargeable AAA batteries into both the parent and baby units. Connect the supplied mains adapters to both units and plug them into power outlets to charge fully before use. Placement: Position the baby unit near your infant but out of reach. Use the wall mount or place it on a stable surface. Keep the parent unit with you; it has a belt clip for portability. Operation: Turn on both units. Use the channel selector to choose one of the two available channels for a clear signal. Adjust the sensitivity and volume controls on the parent unit to your preference. Monitoring: Watch the LCD screen on the parent unit to see baby’s status icons. Listen to the audio for any sounds or cries. Maintenance: Recharge batteries as needed using the mains adapters. Avoid exposing units to moisture or extreme temperatures.
