Not sure what your Babysense 7 control unit is trying to tell you? Don’t worry — we’re here to help. Whether it’s a flashing light, a sound you didn’t expect, or no lights at all, this guide will walk you through what it means and what to do next. With just a few quick steps, you’ll be back to feeling confident that your monitor is working as it should.
My Babysense 7 Control Unit is Flashing. What Does This Mean?
The flashing red LED could mean one of two things:
-
Low Battery Warning
If the red LED is flashing, replace all 4 batteries immediately.
If you also hear a clicking sound, the battery level is critically low.
-
Movement Alarm
A visual and sound alarm is activated if your baby’s movement stops or slows significantly.
Lights on the Babysense 7 Control Unit Don’t Illuminate When Turned ON!
No lights on startup?
Start by replacing all 4 AA batteries with new alkaline ones.
Turn the control unit on again.
If lights appear, perform the Daily Performance Test (instructions below).
If lights still don’t appear, contact our Support Team to solve this problem.
The Daily Performance Test for Your Babysense 7
This quick test ensures your monitor is functioning correctly. Perform it:
Daily and whenever you move the crib, adjust bedding, or change pad placement.
How to Perform the Test:
Make sure your baby is not in the crib at the time of testing
Please remember, removing your baby whilst performing the test or as a test of functioning, is not valid and will not present accurate results.
Turn the control unit ON.
Step back about 1–2 meters.
Wait for up to 20 seconds.
If no movement is detected, the alarm will sound. This confirms everything is working properly.
Repeat the test for each sensor pad individually.
When I Take the Baby Out of the Crib, the Monitor Doesn’t Alarm?
Yes, this would be correct. It's important to know that removing your baby whilst performing the test or as a test of functioning, is not valid and will not present accurate results.
Taking the baby out of the crib is not a valid test of the monitor. Here’s why:
The sudden weight change (from baby removal) results in the control unit readjusting its reading which may take more than 20 seconds. This weight reading is determined from the moment the control unit is turned on.
The algorithm is designed to alert only when weight is constant, but movement slows or stops.
Use the Daily Performance Test in an empty crib instead to confirm that the devices are working as designed.

Troubleshooting for Babysense 7
If you’re having issues:
1. Perform the Daily Performance Test
Follow the test exactly as described above.
2. Check for Environmental Disturbances
These may delay or prevent alarms:
Fans or AC blowing directly on the crib
Vibrating mobiles or toys
Creaky floors or external vibrations
3. Eliminate the Interference
Move or adjust the fan/AC.
Remove mobile toys from the crib.
Ensure the crib or bassinet is not touching anything.
Then perform the Daily Performance Test again as detailed above.
Remember, your Babysense 7 is designed to support you and your baby with reliable, simple safety monitoring. If something doesn’t seem right, start with the Daily Performance Test and check for anything in the environment that could interfere.
