User Manual

Frontier X can be used to monitor your effort, strain and heart rate during any exercise, including running, cycling and swimming. Frontier X is waterproof up to a depth of 1 meter.

You can use the Frontier X device by itself, or with our companion Android, iOS, or Apple watch apps. Frontier X can also be connected as a Heart Rate sensor to the following Garmin watches: Forerunner 245, 935 and 945 and Fenix 5 and above. However, it will only connect to one other device (smartphone or Apple watch or Garmin) at a time.

Connecting your phone to Frontier X

  1. When you unbox the Frontier X for the first time, you need to press down on the Red button for 4 seconds, and then let go. You will now see the red, blue and green LEDs light up on top of the device, and then the screen will come on and show you the logo. Once the device has been activated for the first time, you only need to press the button once to start the device.

  2. Press the red button on your Frontier X once, and the color display on the device will come on, and show you the current time, followed by a summary of your last Workout, and the device Mac ID, as well as battery and memory percentages.

  3. After this, the display will go dark, and the device will show a blinking blue light for the next 5 mins. As long as the device is flashing blue, you can connect the device to the mobile app. After 5 mins, your Frontier X will go into sleep mode to save battery.

  4. While the device is blinking blue, go to the Home Screen of the Frontier X app and click on“Connect” on the top-right corner of the app.

  5. Select the device ID of your Frontier X to connect with it.

  6. Once the device is connected the blue blinking light will turn into a green blinking light. Now you can wear the device and use the app to start recording, generate an ECG report in pdf format, or you can live stream your ECG on your mobile phone.*

Wearing the Frontier device:

  1. First make sure that the electrodes on your Frontier X are snapped on to the buttons on the strap.

  2. Apply some water on your skin and the shiny electrode patches on the strap, to ensure good signal quality during your workout.

  3. Now wear the strap while ensuring that the button of the device is facing down, and the device is located right in the middle of your chest. When worn on the chest, the strap should feel tight, but not uncomfortable. Make sure that the shiny electrode patches on the under surface of the strap are in contact with your skin.

  4. If the weather is cold and dry, and if you are wearing a shirt not made of cotton, please spray some anti-static on the strap and on the inside of your shirt, after you are wearing your Frontier X.

Setting your alert levels

  1. Once you are wearing the device, and the device is connected to the mobile application (blinking green), select the plus sign “Workout” button on the tab at the bottom of your Home screen on the app. This will take you to the “Set Your Alerts” page.

  2. Click on the drop-down menu next to the ‘Effort Alert’, then select the Breathing Rate value at which you would like to be alerted during your training, and then click on “Set Alert”. Wait for 2 secs for the value to be updated on the device.

      

  3. We recommend a level of 40+ for a full-marathon, 45+ for a half marathon, 50+ for a 10k or 5k. But each individual should determine their optimal alert settings by training with the device.

  4. To select the Strain Alert, click on the drop-down menu next to the ‘Strain Alert’, then select the Strain value at which you would like to be alerted during your training, and then click on “Set Alert”. Wait for 2 secs for the value to be updated on the device.
