Please charge them fully before using. The outdoor unit should be installed next to the door on the wall. It can be secured using the provided strong double-sided tape for its rain cover. Once the outdoor unit is inside the rain cover, secure it using the small screws at the bottom to prevent theft. Alternatively, you can drill holes and secure the rain cover using screws. Choose the installation method based on your preference. Indoor unit installation The indoor unit doesn’t require installation. Press and hold the button for ≥3 seconds to turn it on and start using it immediately. Always keep the indoor unit turned on. If you have multiple indoor units, place them in different rooms and use them as intercom devices. After using, place the indoor unit back on its charging base to keep it charged and avoid auto shut-off due to low battery. Tip: Metal objects can interfere with the signal, possibly causing communication disruptions. Try to avoid installing near metal doors or security doors. Tips: The small screws are for securing the outdoor unit to prevent theft. Use the strong double-sided tape for rain cover installation without drilling.
