Audio-Only Mode To Enter the audio-only mode, click the power button to turn the screen off. It transforms the video monitor into an audio-only monitor. Battery consumption reduces by 50%. It allows you peace of mind if you do not want to be disturbed by video at night. You could turn on the display when you want to check on your baby. ECO Mode When the ECO mode is on, the monitor's screen turns off when there is no movement around the camera and turns on again when your baby makes noise. You can choose the sensitivity level. The monitor will be on when noise around 53dB – 58dB is detected. On the Low level, the sound on the camera needs to reach 70dB – 75dB to activate the screen. The High level means that the monitor could easily be activated. The ECO mode saves power and provides a quiet & private surrounding for parents. Scan Mode With extra cameras, you can choose the scan mode for cameras linked to the same monitor. In scan mode, the video would stay 10 seconds on one camera and then move to another.
