Recording with Physilog
Start
• Put all of your sensors on a
table
• Press on the ON/OFF button for
1-2 seconds (green LED on and
off again)

Attach
• Fix the Physilog® on the subject
Sense

press again on the button for a
few seconds
• The LED shines orange, then
blinks 3 times green and then
turns off

Charging and Data Transfer
Plug
•Plug the micro SB to the
Physilog®

files (*.bin) to your
preferred destination
*Charger is not provided by Gait p. Gait p
declines any responsibility due to charger
usage. Please refer to supply voltage in the
product specification section.

Practical considerations
•Make sure Physilog® sensors are fully charged before doing measurements (LED shines green when
connected to computer or charger, you can also check with RTK>check>Battery level) to benefit from the
maximal battery life (given in autonomy section).
•For synchronous measurements with several sensors, make sure to switch them ON at the same time (5-
10sec delay) when they are close to each other. For example, put them all on a table and switch them ON
one after the other. Make sure that they blink green synchronously before placing them on the subject.
•Make sure to know which «.bin» file corresponds to which trial for your analysis – Last digits of file name
are automatically incremented. Note that date of file generation (recorded between one start and stop of
the Physilog®) is visible in the XLS or CSV file.
•Copy trial recordings to your computer,Physilog®4 is not the best place to keep and save important data.
•For Gait Analysis with Gait p’s Gait Analyser (only), sensors can be placed in any orientation, it will not
influence measurements.
•The Physilog® can be used outside. Warning: the sensor is not waterproof.

Handling
•Physilog®4 should be handled carefully. In particular, it should not receive
shocks, such as fall, crushing, being hit, …
•Storage: Store in a cool (0°C – 30°C) and dry place. The provided suitcase is
the perfect place for your sensor.
•Cleaning: Sensors can be cleaned gently using alcohol wipes. Before you
clean the device make sure it is turned off and disconnect all cables.
Caution: Do not put any liquid nearby the micro SB port. Excess of liquid
may damage the sensor. Straps can be washed in a washing-machine.
•Make sure to plug the SB cable in the right way: contact pins should be
centered
•Sensors do not need yearly recalibration.

Troubleshoot
1. First, Visit FAQ on the download section of our website:
http://www.gaitup.com/support/ (from 10.2015
2. If Physilog® is not working properly, please do a simple reset:
Press the reset button once. LED shines ORANGE and then blinks
3. If Physilog® is really not working, please do a master reset:
Maintain the reset button, then maintain main button, release the reset button, and once LED has
stopped to shine ORANGE, release main button. LED blinks ORANGE 3 times
Warning: this operation formats the device and all data stored on the Physilog® will be erased
The aster reset also deletes Physilog’s date and time information. Simply connect the Physilog to the computer and open the RTK
software. If you don’t have RTK, create a new text document using a basic text editing program such as notepad. Leave it empty and
call it TI E.BIN. Check that no other file called TI E is present on the Physilog (also check hidden files). Copy-paste the TI E.BIN file you
created to Physilog.
4. If the problem persists, email it to: [e-mail],
Please indicate Physilog®’s number and attach problematic .bin files if any

Safety information
•Physilog®4 includes a lithium battery. This battery may only be charged over a limited temperature range. Never attempt to dock
or charge your Physilog® when the temperature is outside the range of 0 to 45°C.
•Physilog® should be charged through SB connection with the computer. An external charger may be used ; note that no charger
is provided by Gait p. Gait p declines any responsibility due to charger usage. Supply voltage should be as follows: DC, 5V.
Current consumption is 100mA.
•All external circuits connected to the Physilog® should be «Safety Extra Low Voltage» and «limited Power Sources» circuits as
described in the following standards: IEC60950-1:2005+/A1:2010 and EN60950-1:2006+/A11:2009+/A1:2010+/A12:2011
Warnhinweise:
•Physilog® 4 enthält eine Lithium Batterie. Die Batterie soll nur in einer definierten Temperaturspanne aufgeladen werden. Versuchen Sie nie Ihren
Physilog® an den Computer anzuschliessen oder aufzuladen, wenn die Aussentemperatur nicht zwischen 0°C und 45°C ist.
•Physilog® Sensoren sollen durch eine SB Verbindung mit einem Computer aufgeladen werden. Ein externes Ladegerät kann benutzt werden; Gait
p empfiehlt und liefert aber kein externes Ladegerät. Gait p übernimmt keine Haftung falls ein Ladegerät gebraucht wird. Die erlaubte
Netzspannung ist: DC, 5V. Stromaufnahme beträgt 100 mA.
•Alle an den Physilog angeschlossenen externen Stromkreise sollen die «Sicherheitskleinspannung” und “mit begrenzter Leistung” Regeln erfüllen, die
in den folgenden Normen beschrieben sind: IEC60950-1:2005+/A1:2010 und EN60950-1:2006+/A11:2009+/A1:2010+/A12:2011
Informations relatives à la sécurité:
•Physilog® 4 contient une batterie lithium. La batterie ne doit être chargée uniquement si la température extérieure est dans les limites définies.
N’essayez jamais de connecter ou charger votre Physilog® si la température ambiante est en dehors des limites de 0 à 45°C.
•Physilog® devrait être chargé par une connexion SB avec un ordinateur. n chargeur externe peut être utilisé; par contre Gait p ne livre et ne
recommande pas de chargeur. Gait p refuse toute responsabilité lié au chargeur externe. La tension de réseau devrait être: DC, 5V. La
consommation de courant est de 100mA.
•Tout circuits connectés à Physilog® doivent être «très basse tension de protection» et «source à tension limité» comme décrit dans ces normes:
IEC60950-1:2005+/A1:2010 et EN60950-1:2006+/A11:2009+/A1:2010+/A12:2011
