Frequently asked questions

It’s fast and simple : Tucky is placed under the child right armpit thanks to a double side hypoallergenic adhesive.
1) Check that Tucky is clean and that you didn’t applied moisturizer on the skin of the child.
2) Peel the adhesive from its white base and apply it on Tucky’s sensor side.
3) Peel the remaining protection and place Tucky under the armpit.
Thin and flexible, baby’s movements will not be restricted by Tucky.

The temperature display is colour coded, indicating whether the temperature is normal or not.
– Green : normal temperature (34.7°C to 37.3°C)
Orange : high temperature (37.3°C to 38.4°C)
– Red : very high temperature (higher than 38.4°C)
– Grey : temperature not representative ( e.g. arm open)
The fever alert can be customised, indeed, the default “very high temperature” value is set at 38.4°C and this value can be adjusted by the user based on their child.

No. All the datas are transmitted to the smartphone via Bluetooth Low Energy (BLE) with extremely low power: 1.35mW (classic babyphone: 80-100Mw). These powers are considerably below from those recommended by WHO (World Health Organization).
Tucky takes 1 measure every minute. It does not emit any signal for 99.9% of the time.
Besides an intelligent antenna system reduces even more the level of the signal depending on the position of the child.

Tucky should be applied as soon as fever symptoms appear, and as long as temperature monitoring indicates fever.
It is recommended to change adhesive every 24 hours.

It is rechargeable using the provided micro USB / USB cable: plug the micro USB connector to Tucky and the USB connector to any computer, tablette or AC plug adaptor.
Tucky has a battery life of approximatively one week. Charging time for 100% capacity is 1H30mn. A 15mn charge enables to use Tucky during approximatively 8 hours.

Tucky is water resistant. It is recommended to remove it and to put it back on after bathing the child.

Tucky is available on:
iOs : iPhone 4S and newer versions / iOS 9.0 and newer versions
Android : 4.3 and newer versions

Tucky inform in real time the parents of the child’s position with an icon that indicates whether the baby is lying on his back, on his stomach or on his side. Thus they can control the position recommended by the pediatrician or doctor. You should know that if you place Tucky under the left armpit, the position’s pictograms will therefore be reversed.

The range is around 10 meters (32 feet). It may vary upon the nature of the obstacles that could interfere with the signal. If the connection is interrupted, the data is not lost. The data is stored by Tucky and sent as soon as the connexion is restored. The process is completely transparent for the user.

Tucky measures temperatures between 75.2°F and 111°F.
It’s important to know that axillary temperature is usually 0.6-0.7°Clower than rectal temperature. The accuracy of the measurement is part of the essential performances of this medical device. That performance is guaranteed by tests carried out under the ISO EN NF 80601-2-56 standard.

Use a cleansing cloth or cotton soaked with alcohol. Make sure the USB plug protective cap is on before cleaning Tucky.

Tucky passed all the mechanical and thermal robustness tests of the ISO EN 60601-1-11 standard.
Nevertheless, Tucky is a medical device that must be handled with care. Its flexibility allows it to perfectly marry the child’s body but not be bent repeatedly.

No. All materials used for Tucky and for the adhesive are bio-compatible. They have successfully passed sensitivity, irritation and cytotoxicity clinical testing to be applied on skin.
However, if you want you can place Tucky under the other armpit (left one) you should know that the pictograms of the child’s position will therefore be reversed.

Usage questions

First of all, here is some information on the proper use of the product:
– Tucky measures the temperature of the axillary artery. It should therefore be placed as high as possible in the hollow of the armpit, and the child should be properly dressed.
– The exact temperature is obtained after keeping the arm closed for about ten minutes. It is then necessary to add 0.7°C to have the rectal equivalent.
– If the child\’s arms are open for an extended period of time, the measured temperature may drop. The grey colour indicates that it is no longer representative. In this case, it is necessary to refer to the last highest peaks of the curve.
– The threshold for triggering the alert can be modified to suit the particularities of each child.

Remote connection is possible using a “relay” phone.

On a first phone (relay):

  • Download the Tucky application, and log in with your login / password
  • Associate it with Tucky (Bluetooth connection) and leave it close to the child

Note: Make sure the internet connection is working, and the battery is full.

On a second phone:

  • Log in to the Tucky application with the same login/password.
  • Go to the child’s profile and refresh the view (pull down).

Note: A cloud icon indicates that the data is from the cloud. There may be a delay of a few minutes in the display.

To modify the temperature alert threshold, simply:

  • Go to the parameters of your child’s profile,
  • Change the temperature to the desired one and record.

However, all fields (name, gender, date of birth, weight and height) must be filled in for the alert modification to be effective.

To activate the reversal alert (position monitor) it is necessary:

  • Go to the child’s profile
  • Press the “menu” button at the bottom left of the screen
  • Enable position alert

Be careful, the position alert is by default inactive for each child.

To verify that the alert sent by the phone is working properly, you must:

  • Select the desired alert tone in “account setting” (Android only)
  • Use the “test alert” button in the child’s profile.

A notification and a ringing tone are triggered on all phones connected to the same Tucky account.

After changing the “Fever Alert” value of a child profile, switch the associated Tucky off and on again.

Technical problem

Your Tucky seems to be connecting, but you don’t see a temperature display. There may be a Bluetooth connection problem.

You can perform the “Tucky update” procedure to unlock it:
1- In the application, “dissociate” the Tucky from the child profile
2- In the Bluetooth settings of the phone, “dissociate / forget” Tucky
3- Switch off the Tucky (the LED flashes 1x), then switch it on again with a long press (5 seconds): the LED flashes slowly.
4- Return to the Tucky application, go to “Home -> Account Settings -> Update Tucky” and press “Update Tucky“.
5- Go back to the child profile, and “re-associate” Tucky

Note: On other phones that usually connect to Tucky, you will need to perform the action described in point 2 (dissociate Tucky in Bluetooth settings).

You can’t turn on your Tucky and the LED flashes several times each time you press it?

The normal behaviour of the Tucky during charging is as follows:

  • When you connect Tucky, the LED lights up continuously
  • When the charge is full, the LED turns off (the charging time can last between 5 minutes and 2 hours)
  • Once connected to the application, the battery icon should display 5 bars

If you don’t have this behavior, then:

  • Try another USB cable
  • Use another charger or the USB port of a computer

If the problem persists, we invite you to contact us via the complaint form below indicating whether or not your LED lights up after a long press (5 seconds).
