Place it on a firm, level surface at least 30.5 cm from the wall, out of children’s reach; keep the unit and cord more than 0.9 m from the crib. The manual says not to use it in a closed room or when humidity exceeds 50%. For app use, the manual requires a 2.4 GHz Wi-Fi network with download and upload speeds above 2 Mbps.
Regular care matters
The manual calls for daily maintenance and weekly cleaning, plus filter care suited to the water used. Unplug and empty the unit before cleaning; do not immerse the base.
