1. We strongly recommend attaching the ACT Head Impact Tracker sensor to a head accessory of user's choice, also when wearing a helmet. The sensor can
be attached to almost any kind of head accessory or wear, with hook and loop -tape. Head bands specifically designed to accommodate the head sensor has
been developed and are many cases available for purchase in same webstores as the sensors.
2. Always place the sensor so that its head side (i.e. the side with the foam, on/off-button and LED light is facing your head). If you use a head band, the
sensor is to be placed between the head and the head band.
3. WARNING! Place the sensor only in a location where impacts or pressure do not occur.
4. If you feel pressure or discomfort when wearing the sensor, change the sensor placement.
5. If you consider attaching the sensor to a helmet, refer to your helmet's User Manual, Owner's Guide or corresponding document to verify if it is possible.
Always follow the helmet manufacturer's instructions on safe helmet use. Only use a helmet that meets the applicable safety standards when you use a
helmet with ACT Head Impact Tracker head sensor or ACT Head Impact Tracker Pro head sensor.
Examples on wearing with ACT Head Impact Tracker Accessories (head band or dock) or attached to the helmet:
GOOD TO KNOW
We believe that today there is not sufficient medical research to reliably, simply and safely classify the individual impacts or events as "small-medium-hard"
or "red-yellow-green" for example on the basis of g-force or angular velocity. In the absence of proven, reliable, scientific results ACT Head Impact Tracker is
not telling you "when the impact is too hard, or when it is not", nor will it tell you "when you have to seek medical help, or when not". There is simply no safe
way for a measuring device to do so. Not yet. That's why more data and research is needed. One rule of thumb applies though: the more violent the impact
or event, the bigger the forces acting on it, and the chance for damage to occur.
In case of a head impact, or when suspecting one, immediately and safely leave the activity and seek help from licensed medical professionals. It is advisable
to have an accompanying person if concussion is possible.
NORMAL MODE AND TRACKER MODE
ACT Head Impact Tracker head sensor has two modes to it.
Normal mode. Recommended mode to use when you have solid Wi-Fi or mobile data connection available throughout the session. This is how it works:
1.) Switch the sensor on by pushing on/off button once. LED light blinks long once and then in slow frequency, 1 short blink in every 5 seconds. 2.) Open ACT
Head Impact Tracker smartphone mobile App, log in, ensure location and Bluetooth wireless connection, Nearby Devices (if applicable), Wi-Fi or mobile
data connections (and roaming if needed) are enabled, on and active. Stay logged in and keep App open and active throughout the whole session duration. If
possible, keep the phone open and active (screen lighted), since some mobile phone brands and models may disconnect Bluetooth wireless connection if
phone is going to power save mode. If this happens, the sensors cannot transfer data to the App. 3.) When the sensor detects an impact/event 10g or over, it
tries to send the information to the mobile device with the App immediately using Bluetooth wireless connection. 4.) If the information is not successfully
transferred to the mobile phone with the App (the distance between the sensor and mobile phone is too long, data connections are not available or are busy,
phone is on power save mode and has disconnected Bluetooth wireless connection for the App for example), the sensor saves 464 impacts'/events'
information to it and tries to send them always when the sensor is on. The sensor will transfer all the impacts from its memory using First in Last out -
principle. When the small ACT-icon disappears from the left-hand upper corner of the phone and does not reappear or impacts/events with index numbers
missing from the impact history have appeared to the impact history, the sensor's memory is empty. 5.) Even if using normal mode, some impact information
is frequently saved in the sensor's memory. Hence, we recommend keeping an eye on the impact history. If impact information seems to be missing or impact
history is missing index numbers (#X, #XX, #XXX), download the impact information from the sensor. It is recommended to do this every time before the
battery is changed, because after changing the battery the time stamp of impacts/events saved prior the battery change will not be accurate.
Tracker mode. Recommended mode to use when you do not have Wi-Fi connection or mobile data connection available throughout the session. Using
Tracker mode will save energy and prolong the battery's life span. What happens on the tracker mode is that when the sensor detects an impact/event 10g or
over, it saves the information. No attempt to deliver information in near real time. To retrieve the information from the sensors after the session, switch all
sensors off and switch them back on one by one so that the sensor is in the proximity to the mobile device with the App - which is connected to Wi-Fi or has
mobile data (and roaming if needed) connection. The sensor will transfer all the impacts/events from its memory (depending on the number of
impacts/events, this can take from few seconds to approximately 1 minute or even more). It is recommended to do this every time before the battery is
changed, after the battery is changed the time stamp of impacts/events saved prior the battery change will not be accurate.
To activate Tracker mode. 1.) Switch the sensor on by pushing on/off button 1 time. Check that the LED light starts blinking in slow frequency to indicate that
the sensor is on. 2.) Push the on/off button once for about 2 seconds (keep the button pressed for 2 seconds) until the LED light blinks 3 long blinks and then
starts blinking in slow frequency (1 blink / 5 sec). Tracker mode is activated, no real time impact data will be sent, and impact information will be saved in the
head sensor's memory. Please note: you first have to switch the sensor on and only then Tracker mode can be activated.
To deactivate Tracker mode: push the on/off button once for about 2 seconds, so that you can see the LED light activating (then release the button) and
blinking 4 long blinks to indicate Tracker mode is deactivated and sensor is back on normal mode (the slow LED light blinking continues). Alternatively, you
can turn off the sensor when it is on Tracker mode.
