The Motorola MBP161 Timer Digital Audio monitor uses DECT interference free technology that offers a strong wireless connection. This means better range & less chance of you missing something important. Two-way communication means that you can speak to your little one & with the high sensitivity microphone you will hear every sound coming from your baby's room. The MBP161 Timer has 3 activity timers pre-set so you can set a time when your little one needs their sleep, nappy changing or milk feeding & have an alarm to alert you. The baby unit features an entegrated night light which help calm your baby while the integrated lullabies help soothe your baby to sleep. You can adjust the volume of the sound to best suit your surroundings. Room temperature monitoring is enabled & displayed on the parent unit thanks to the integrated thermometer.
