The sensitivity level on all Angelcare Movement Monitors is preset when you use them for the first time - yours is level 2. This is suitable for most standard cots, cots beds and should only be adjusted if required.
To ensure that the sensitivity level of the monitors is correct for your baby's mattress carry out the following Four Corner Test for your model:
Please Note: your baby must NOT be in the cot during this test.
Switch the Parent & Nursery Unit ON.
Gently place your hand on the surface of the mattress in the furthest corner and wait for 20 seconds.
*If the movement alarm does not sound from the Parent & Nursery Unit (series of loud continuous beeps) repeat in the remaining 3 corners.
Remove your hand from the mattress and step away from the cot (the Sensor Pad is sensitive enough to detect your movement if you are touching the cot)
**Due to the lack of movement, after 20 seconds the movement alarm will sound from the Parent & Nursery Unit.
Place your hand on the mattress and after a few seconds the alarm will cease - this is because the Sensor Pad has detected your movement on the surface of the mattress.
*If the alarm sounds when you place your hand in any of the corners turn the sensitivity up a level and repeat the Four Corner Test.
**If the monitor does not alarm when you step away from the cot, turn the sensitivity down a level and repeat the Four Corner Test.
If the Four Corner Test does not resolve your query
Have you tried replacing the CR3032 Lithium battery in the Sensor Pad - it is recommended that this is replaced approx every 4-6 months to prevent false alarms. Some batteries can have a shorter shelf life that others so always try replacing the battery.
This battery is available from online stores.
· Is your baby asleep when you go in to check?
If yes, this would indicate that your baby is in a deep sleep as the alarm has not woken the baby
· When you check on your baby does the alarm continue or does it cease on its own?
If the alarm ceases on its own this will be because the alarm has re-established your baby’s sleeping pattern. If the alarm does not cease on its own please let us know.
· Does the alarm only happen at night?
If yes this is because your baby, as with adults, can go into a deeper sleep at night rather that when they nap during the day
· Is there a particular time that this is happening?
Babies have sleeping patterns when they go into deep sleeps and, because of this, the alarm can go off at certain times in the night
· Are you using additional sleep aids such a Sleepyhead, Cocoonababy etc.?
The more that you place between your baby and the Sensor Pad the harder it is for baby's movement
If you are using such products we recommend that you also carry out the Four Corner Test on the surface of the sleep aid to ensure that your baby's movements transfer down.
· What type of mattress are you using?
We know that the Sensor Pad will work effectively with a standard hypoallergenic, spring, coir (and spring/coir combined) mattress as these allow your baby’s movements to be transferred down on to the pad.
We also know that the Sensor Pad will NOT work with a Hollow Framed, Dual Sided, Memory Foam Mattress;
A Hollow Framed Mattress is mainly a US product. It is basically a number of poles that are fitted together with a tight cover fitted over this. As a result of there being nothing actually inside the mattress (hollow), no movement is transferred down to the Sensor Pad. Because of this the monitor may false alarm indicating that baby's movements are not being detected by the Sensor Pad.
A full Memory Foam or Dual-sided Memory Foam Mattress masks the movement of your baby on the surface of the mattress due to the density of the foam and baby's movements do not transfer down to the Sensor Pad. As a result, the monitor may false alarm indicating that baby's movement is not being detected by the Sensor Pad.
