PLACE AT ARMPIT LEVEL SENSOR SAFEABOUT SENSORSAFE
SensorSafe is a smart chest clip that uses Bluetooth® technology to connect to the CYBEX mobile application, where caregivers can receive four types of safety alerts:
• Vehicle interior temperature too hot or too cold
- Chest clip has become unbuckled
- Time to take a break (chest clip has been buckled for more than 2 hours)
- Caregiver has moved away from a buckled chest clip (i.e., child is left in car)
USING SENSORSAFE
⚠ WARNING! DEATH OR SERIOUS INJURY CAN OCCUR
This product contains magnets. Before use, consult your family doctor about the compatibility of this product with pacemakers and similar devices.
Important: After you connect to SensorSafe for the first time, familiarize yourself with each of the alerts before using it with a child in the seat. Confirm all mobile phone settings to ensure alerts are audible and functioning as expected.
Helpful tips before getting started:
- The set-up process will take a couple of minutes. We recommend connecting to the app without a child in the seat.
- You can connect to the seat directly out of the box, even prior to installing it in the vehicle!
- Go through the set-up process for one caregiver and one car seat at a time. Others can be connected later.
- The only things you need are a car seat and a compatible mobile phone. Ensure your mobile phone is compatible with SensorSafe by checking sensorsafeapp.com/device-compatibility.html

per (1) Caregiver App
- SensorSafe chest clips transmit when they are buckled. Leave all SensorSafe chest clips you are near in the unbuckled position to start.
Trademarks are the property of their respective owners.
Prepare the SensorSafe Chest Clip
- Start by opening the chest clip and leaving it in the unbuckled position.
- On the side of the chest clip with the SensorSafe logo, firmly pull on the battery pull tag to completely remove it.
- Discard the tag.
Prepare the CYBEX Mobile Application
- Download the free CYBEX mobile app to your smartphone, then create an account in the app by using your email or an Apple log-in.



Important: Set up the CYBEX app to automatically update or check back for updates regularly to benefit from new features being released.
- Select if you want to create a new family or if you have been invited to join an existing family. A family is a group of users who will be monitoring the child either as the primary caregiver or as a family emergency contact. You can add as many family members and car seats as you like to each family member's account.
- Create New Family. If you are the primary caregiver or the first member of your family connecting to a CYBEX product, choose this option to create a family, then follow the instructions to add new members to your family via an email invitation.
To ensure notifications reach family members in an unsafe situation, we recommend adding a minimum of two family member contacts.
- Join Existing Family. Family members will select this option after receiving an email invitation to join an existing family. They will be asked to download the CYBEX app, create a profile, and enter the one-time family invitation code from the email to join a family.

Hello Emma, nice to meet you! Please select if you want to create a new family or you've been invited to join your existing family Create New Family Join Existing FamilyFamily members only receive alerts in case the primary caregiver has not responded to a Child In Car alert within approximately 3 minutes. The alert will arrive to the family member whether or not the app is open on their phone. Family members are not able to remotely monitor the condition of the seat other than receiving the Child In Car alert.
Family alerts are sent over Wi-Fi or a cellular data connection. If you are out of range of cellular service, the alert will not send until service is restored.
If a family member has not yet accepted your invitation, a re-invite button will appear by their name in settings.

NJ! Natalie Jones Aunt REINVITE >- Please always allow all mobile app permissions for the SensorSafe system to function. If any of these are turned off, safety alerts may not be received:

Bluetooth is how the mobile app receives the transmissions from the SensorSafe chest clip.

Location is used in the moment when a buckled chest clip is away from the mobile app (Child In Car) to inform caregivers and family members of the child's location.

Notifications are used to send safety alerts directly to the caregiver's or family member's attention on the mobile phone's home screen.

Critical Alerts (Apple® Only) are enabled to allow the app to sound the Child In Car alert even when the phone is in Silent Mode.
- Correctly identify which SensorSafe product you own.
- Clip Only. Choose this option if you unbuckle the chest clip and see the letters "S3" stamped on the tongue.

Helpful Tips:
- Ensure all mobile application permissions are always turned on and enabled: Bluetooth, location, notifications, critical alerts.
- Have sound volume on and disable “Do not disturb” to benefit from all alert types.
- If any alert does not function as you would expect it to, contact CYBEX Consumer Services using the information in the CYBEX mobile app or URL/phone number in your child restraint user guide, as specific instructions may be available for your mobile phone model.
Child In Car
First Alert - If you walk away from a buckled child, you will receive an immediate alert at around 7.6 meters (25 feet). Walk back to the child and unbuckle the chest clip to stop the alert.
Notes:
- SensorSafe Child In Car notifications work by measuring the Bluetooth signal strength from the chest clip to the phone. Signal strength may vary depending on the mobile phone or the environment, so the distance at which you receive the alert may vary from user to user.
- Always test the alerts prior to using SensorSafe with a child. Observe the home page during testing so you can see at which distance SensorSafe disconnects in your environment.

Alert CHILD STILL IN CAR. (Nathan) Location 120 Royall St. Canton MA CHECK VEHICLE! 34m ago- This alert will sound at full volume so that it can be heard in an emergency.
Second Alert - If you ignore the first alert for more than 2 minutes, you will receive another alert indicating that the app is about to notify your family emergency contacts.
Third Alert - If all previous alerts are ignored, you will receive a notification that your family emergency contacts have all been notified with the location of the child.
Temperature
Temperature alerts will sound if the temperature rises above 35^ C / 95^ F (too hot) or falls below 7^ C / 45^ F (too cold). The alert will repeat every 5 minutes until the temperature is within a safe range.
Note: If your car seat has been in a very hot or cold temperature for an extended period of time, it may take some time for the chest clip to register a rapid change in temperature (potentially due to air conditioning or heat).
Clip Open
SensorSafe will notify you each time the chest clip has been unbuckled. This is a one time notification and will not repeat.
Extended Time in Seat
If a chest clip has been buckled for over 2 hours, the caregiver will receive an alert reminding them to take a break to let the child move and stretch. This alert will repeat every 30 minutes until it is acknowledged.
Other Alerts
You may also receive alerts from the CYBEX mobile app when settings do not allow full function of the system such as when permissions are turned off, the battery is low, or you have closed the app.
Other App Features
Browse through the CYBEX app to familiarize yourself with features such as instruction manuals, videos, FAQs, personalized settings and profile management. Often the information you may be looking for is right in the app.
When removing the child from the car seat, always leave the SensorSafe chest clip in the unbuckled position to preserve battery life. If it remains buckled, the chest clip will cycle through the Child In Car sequence, then, after 12 hours of inactivity, will go to sleep and stop transmitting. It will not turn on again until it is re-opened and closed.
LED LIGHTS
The SensorSafe chest clip LED lights are designed to tell you two things: (1) if the chest clip is connected to the app, and (2) if the battery is fully charged or low. This table shows how the LED lights on the front of the chest clip will behave:
| Slow Blinking = Full Battery | Rapid Blinking = Low Battery | ||
![]() | RED LIGHT= Not ConnectedA red light indicates that the clip is not connected to the app. | 1 red blink per second until the SensorSafe clip is connected (up to 30 seconds) | 10 rapid red blinks indicate a low battery while the clip is not connected |
![]() | BLUE LIGHT = ConnectedA blue light indicates that the clip is connected to the app. | 2 slow blue pulses indicate a successful connection | 10 rapid blue blinks indicate a low battery while the clip is connected |
