Bodytrak Earpiece User Manual

Bodytrak Earpiece

Bodytrak I is the first precision physiological monitoring solution compromising a non-invasive ear-based sensor device which measures physiology, motion and ambient noise exposure whilst simultaneously enabling ambient noise transparency and audio communications to maintain situational awareness. Since the product accesses the ear, the only body site from which all vital signs can be measured non-invasively, Bodytrak is able to continuously measure several key parameters, including: aural and core body temperature (CBT), heart rate (HR), heart rate variability (HRV) and biomechanical motion metrics.

Earpiece

The earpiece is the central node of the Bodytrak system combining purpose- built physiological and biomechanical sensors, an audio speaker and real-time onboard processing units inside a miniature plastic enclosure that securely fits the human ear cavity. The earpiece has been designed to sit flush with the ear contour and allow a full-size helmet to be worn.

A flexible ear hook can be adjusted to wrap snugly around and behind the helix for a personalised fit. Provided replaceable silicone ear buds and wing tips have been designed to position and secure the earpiece in the ear cavity (the “concha”).
Bodytrak supplies the consumable silicones in a standard size which are applicable to the majority of users.

Communications Pack

The Communications Pack plays an integral role in the Bodytrak solution, depending on the targeted deployment. The Communications Pack supplies power to the Bodytrak earpiece and receives data input from it to be stored in its internal non-volatile flash memory, alongside a real-time timestamp supplied by an internal real-time clock (RTC). The Communications Pack can relay collected data in real-time through a Bluetooth-enabled third-party device using Bluetooth Low Energy (BLE) services, receive audio using Bluetooth EDR, and send real-time data to the Bodytrak Cloud using WiFi (2.4 GHz) and cellular (LTE and 3G) technologies.

Set Up

Connect the earpiece to the Communications Pack by pushing the earpiece connector into the Communications Pack USB-C connector. Pull lightly on the connection to ensure mating has occurred.

WARNING: USB-C connector is not compatible with generic USB accessories. Do not plug any accessories apart from the Bodytrak earpiece, otherwise warranty is void.
The Communications Pack has 3 buttons that are used for operating the device: “Power”, “Vol Up” and “Vol Down”. The buttons are designed to not be accidentally pressed and require a firm press with the tip of the finger or thumb. If the Communications Pack does not perform the desired action when a button is pressed, slightly more force will be required specifically through the center of the button.

Powering On/Off
To power on the Bodytrak system first set up the Communications Pack and earpiece as described above, with the earpiece plugged into the Communications Pack. Turn on the Communications Pack by holding the “Power” button for 2 seconds at which point the System light should flash green indicating a boot- up process has started. To turn off the Communications Pack hold the Power button for 5 seconds until the System light turns off.

Reset
To reset the Communications Pack press and hold both the “Vol Up” and “Vol Down” buttons for at least 10 seconds until the display turns off.

Charging (using Bodytrak Charging Cradle)
Insert the Communications Pack into the Bodytrak Charging Cradle making sure the device sits upright. Connect the Charging Cradle to the supplied USB-C wall adapter with a USB-C cable.
A breathing green light indicated the device is currently being charged. It may take up to 2.5 hours to charge the battery fully. Once charged, a solid green light will come up.
Device is designed to be charged by a dedicated USB charging port that can provide up to 2A 5Vdc (up to 10W). Charging current is internally limited to 1A 5Vdc (5W).

Charging (using Bodytrak Charging Hub)
Optional accessory is available to support up to 10 Communications Pack units charging simultaneously. Insert the Communications Pack into the Bodytrak Charging Hub making sure the device sits upright. Connect the Charging Hub to a conventional AC power socket using the supplied power cord. Activate the Charging Hub by toggling a power switch located next to the power cord exit. Please refer to the Bodytrak Charging Hub (BCH1X) user manual for further information.

Over-the-Air Software Updates
The Communications Pack automatically downloads the latest software over-the- air (OTA) while it is placed on charge. Device will attempt to connect to the Bodytrak Cloud via cellular or WiFi during the first few seconds after being inserted into the Charging Cradle. Display provides information about the current stage of the update cycle.

If new software is available for the Bodytrak earpiece, it will be installed next time it’s inserted into the Communications Pack. The earpiece update procedure adds 60-90 seconds to the boot-up time.

NOTE: Do not disconnect the earpiece during the update procedure. Refer to the on-screen information to learn about the current software installation stage.

Environmental Considerations

Bodytrak I is certified to be used down to -10°C measured at the battery cell. Due to various environmental and atmospheric conditions, the battery cell temperature does not always correlate to the ambient temperature. Bodytrak I will continue to operate below -10°C ambient temperature for a short period of time until the internal cell temperature reaches -10°C and the device shuts off safely. It is recommended to protect the device from exposure to extremely negative temperatures by wearing it inside personal protective equipment where applicable.
Similarly, Bodytrak I is certified to be used up to +60°C measured at the battery cell. Bodytrak_I can be used in environments with higher ambient temperatures providing the device is protected from direct sunlight and heat exposure. At no point the internal temperature of the device should exceed +120°C.

Bodytrak I should never be used in a potentially explosive environment.

Bodytrak I is not suitable for full water submersion. Device can be cleaned by wiping its surfaces with a soft cloth and a suitable disinfectant.
Bodytrak I should never be operational at an altitude exceeding 4,000m (13,000ft) above sea level.
