If the alarm does not sound when you step away from the cot reduce the sensitivity down a single level and repeat the 4 Corner Test. Keep adjusting the level until the alarm sounds ensuring that movement is still detected in all four corners A full Memory Foam or Dual sided Memory Foam Mattress masks the movement of baby on the surface due to the density of the foam: again, movements do not transfer down to the Sensor Pad. As a result, the monitor may false alarm indicating that movement is not being detected by the Sensor Pad.

Install the sensor pads under the mattress. With the printed side facing up, place the sensor pad under the crib's mattress in the middle of the crib. No bedding should be between the mattress and sensor pad. Secure the sensor pad using a tie wrap.

Does it take long to set up?To set-up the functions of each Sensor Pad, make sure you have selected the relevant Nursery Unit. This information will be displayed on the blue top info bar. Although the batteries are not included in the nursery unit, it is wise to buy your own batteries and use them in case of a power outage. The AC327 allows you to add a second Camera Unit & Sensor Pad so that you can monitor two babies at the same time (in separate cribs). This could be very helpful for twins. Now that you have 2 Sensor Pads linked to your monitor, you'll be able to set the Sensor Pad sensitivity accordingly to the mattress. You will see the Sound Function (Speaking face) Icon flashing in the top right hand of the Parent Unit screen:
