Nevertheless, please read carefully the instructions presented in this user manual and use it whenever necessary. Destination and use case: eTact® is a device intended to measure the activity level as well as the raw acceleration data and give an indication of the skin temperature. 1. Important Safety Warnings The safety procedure presented in this document must be carefully followed.
DO NOT CHANGE THE BATTERY DO NOT CLEAN IN WATER/LIQUID (IMMERSION) Do not dispose of eTact® with household waste. The patch and the cable have been designed to be recycled. The crossed-out wheeled-bin waste symbol indicates that the device (electrical equipment, electronic primary battery or rechargeable battery) must be disposed separately from ordinary household waste.
To get the device active, you simply need to connect the cable on the patch and connect it to a USB plug or to a computer USB port. The blinking LEDs indicate the patch is active.
Picture 1: The eTact® patch It should be noticed that the plastic grey cover opens from the left side of eTact® when this one is held in front of you. When using the X, Y, Z raw data, it is important to know the device orientation.
Be careful, in memory mode when the patch is switched off due to lack of battery during the acquisition phase, it is essential to recharge the patch AND use the eTact® Watcher interface, in order to update the time & date. This step is necessary to allow the patch to store new timestamped data properly.
PC/MAC USB port. The cable provided by the manufacturer is the only one compatible with eTact®, providing an optimum functionality and safe operating conditions.
PC/Mac through USB port - Visualize the data: the software can display temperature & activity data day per day. If you want to get access to all option, eTact® Watcher requests to connect the cable to the PC/MAC and then to the eTact®.
Picture 5: Main menu when the device is operational Some buttons are available and allow different actions: Select language: French / English Setting eTact® internal clock Switch off the device (stops ongoing recording and sets the patch in shelf mode) 6.2.
General settings User has the choice to set eTact® patch in two different modes: Memory mode: all the data are stored in the memory and available on eTact® Watcher through the cable. Bluetooth/memory mode: advanced mode which require the creation of an Android application to save and display the data.
P090GUI003.2 6.2.2. Temperature measurement settings It is possible to select the temperature measurement period setting with a value in min or s. (from 30s to 30min) Picture 8: Temperature acquisition setting 6.2.3. Accelerometer settings The accelerometer range is +/2G. The accelerometer acquisition frequency can be set to 25Hz or 50Hz. Options are suggested giving the possibility to provide complementary acceleration data: Fixed option: takes the instantaneous acceleration value just at the end of the chosen sampling period (from 30s to 30min)
Adjust the acceleration threshold to compute the activity level (a 0.1G threshold correspond to an acceleration value of 1.1G). Picture 10: Activity settings 6.2.5. eTact® programming After the « Apply » icon has been pushed (Configuration window), a new window opens and indicates the programming status.

P090GUI003.2 Warning: the first part of the configuration is a full and automatic erase of eTact® memory. This action will take a few minutes. The remaining time before the erase completion is indicated. It is strictly forbidden to disconnect the patch or the cable during this time, otherwise the system could be damaged.
The recorded data into the internal memory of the patch can be downloaded through the cable connected to a PC/MAC. In the main eTact® Watcher window, a simple click on the “Download” button is necessary. During data download, it is strictly forbidden to disconnect the patch or the cable from the computer otherwise the system could be damaged.

At the end of the data transfer, a window is displayed to select the root for the .CSV file generation. Picture 18: Downloaded data file saving After the download is finished, a confirmation is requested to keep or erase the eTact® memory. This action is definitive. However, it only concerns data, the configuration settings remain in the memory.
