Product Overview
Thank you for choosing the TgForce Impact Running Sensor. The sensor and its associated App provide
real time tibial shock feedback and additional features. This document provides instructions on
installing and operating the sensor. It also provides mandatory regulatory information. Please check
tgforce web site at http://tgforce.com for the latest information.
We recommend following the guidelines in this instruction manual before using the TgForce Sensor.

Charging and activating the sensor
Charging
Before first use, it is recommended to fully charge the TgForce sensor. Plug the provided USB charging
cable into any USB port. Charging your sensor will take approximately 1-2 hours. When charging is
complete, the orange LED indicator light will turn off.
Activating the sensor
Slightly shaking the sensor will activate it. If the sensor was in sleep mode, LED indicator light will flash
red 5 times (or blue if an iOS device with TgForce App is active nearby). Note that the sensor does not
have an On/Off Switch. If the sensor has been unused for more than 10 minutes, it will enter sleep mode
to preserve battery charge. It will also enter sleep mode if the sensor is not paired within 2 minutes,
Pairing the TgForce Sensor
The TgForce App will automatically look for a nearby TgForce sensor and establish pairing. You can
confirm pairing has been successful by looking at the Bluetooth icon in the upper left corner of the
TgForce App. When successful pairing is established, the sensor LED indicator will flash blue 5 times.
Alternatively, you can pair the sensor manually by selecting the Settings Tab and ‘TgForce Sensor’.
Pairing has been successfully established.
There is no pairing with the TgForce sensor. Try shaking the sensor until pairing occur.

Version 1.4 TgForce Sensor User Guide P a g e | 8Page 8
Attaching the TgForce Sensor
For accurate measurement, the sensor
must be attached to the anteromedial
aspect of the distal tibia
(in front and toward the middle of the
lower extremity). Use the provided
Velcro band. The Sensor must be
attached in way that is tight enough so it
does not slide on the skin.
It is very important to have the sensor
visual LED indicator on top; the charging
hole must be downward.
Note: The sensor can also be attached
using Adhesive tape such as the 3M
Nexcare Water Resistant Adhesive Tape.
If the sensor cannot be attached firmly
with the Velcro band, use this method.

Start Running
Push the Start button on the app. Once
you start running, you should see Impact
data being received and displayed.
If Audio feedback is activated (in the
Settings menu), you will be notified in
your earphone if the impact level is
above the gMax threshold.
You can adjust the gMax threshold in the
Settings menu.

Getting to know the TgForce App
The main Session view
PPA
The PPA (Peak Positive Acceleration) of the Tibia while
running is displayed in real time in g unit. It is the maximum
acceleration that occurs during the impact phase of running.
AVG
This is the average PPA for the session. Calculated over the
displayed number of steps.
Cadence
Number of steps per minute - counting both feet.
gMax Red threshold line
The gMax threshold can be adjusted in the Settings menu.
The top PPA value will switch from blue to red every time
the impact value is higher than the gMax threshold value. If
Audio Feedback is enabled, an audible sound (selectable in
the settings menu) will also be generated.
Start/Stop
After a session has been started with the Start Button, only
the Session screen is available. The Settings and History
screens are available after stopping a session.
Stopping the session will provide 3 options: Saving the data
in history, Discard the session data and Resume the session.
