AC401 / AC403: Why: my monitor does not alarm when I take baby out of the cot

Firstly, has the sensitivity dial on the back of the Nursery Unit been changed accidentally. If the setting is too high the Sensor Pad can continue to detect movement near to the crib such as floorboards, central heating, even something as light as a fan.

In addition to this when monitoring baby’s movements you should not use a mobile, toy that plays music etc. in the crib – these all emit a form of movement, albeit small on the surface of the mattress or the crib itself. Whilst the Sensor Pad is able to detect movement it is unable to distinguish between baby’s movement or something inside or attached to the crib.

Also, please do not place the crib directly against a wall, skirting board as it can detect movements from piping etc.

Lastly, if you are using a bedside crib you are unable to use the Sensor Pad when it is attached/touching your bed. When any bedside crib is attached/next to your bed the Sensor Pad cannot be used as it is sensitive enough to detect your movements in your bed.

The Sensor Pad cannot differentiate between the movements of baby or you and may not alarm

If you have not already done so carry out the Four Corner Test below. This will establish the correct level of sensitivity required for your baby`s mattress so you can adjust accordingly (only if required):

NOTE: Please follow step 2 within 20 seconds after turning ON both units otherwise the movement alarm will sound. Your baby must NOT be in the crib during this test:

Check that the sensitivity on the back of the Nursery Unit is at level 3 (factory setting), if not move dial until at number 3

Switch the Nursery Unit & Parent Unit ON

Gently place your hand in the furthest corner of the mattress & and wait for 20 seconds

*If the pendulum symbol on the Parent Unit screen swings and the green light flashes on the Nursery Unit registering your hand then the sensitivity is correct and repeat in the remaining 3 corners

Remove your hand from the mattress and step away from the crib. The Sensor Pad is sensitive enough to detect your movement if you are touching the crib

**Due to the lack of movement, after 15 seconds a single beep (The Rouse Alarm) will be emitted from the Nursery Unit

After a further 5 seconds a series of continuous beeps (The Main Alarm) will sound from the Nursery Unit & Parent Unit

Place your hand on the mattress and after a few seconds the alarm will cease as the Sensor Pad will have detected your movement

*If the pendulum does not swing and the alarm sounds when you place your hand in any of the corners, please adjust the sensitivity by turning it up another 1/2 a notch and repeat the Four Corner Test again.

**If however the monitor does not alarm when you step away from the crib reduce the sensitivity down 1 level and repeat the Four Corner Test, keep adjusting this until the alarm sounds ensuring that the movements is still detected in all four corners.
