CORE Manual - Battery and Charging

The CORE sensor battery lasts for over 6 days. Inside the settings the standby mode can be enabled and depending on the amount of use, can extend the battery life for up to 1 month.

Charging the CORE sensor

The CORE sensor is rechargeable and is supplied with a magnetic charging cable that can be plugged into standard USB outlets (on a computer or wall-socket / power point). Recharging takes about 2 hours.

Please take care with the charging cable, unplug it when not in use and avoid the magnetic contacts from connecting to metal items (which can cause a short-circuit).

Some external USB battery packs will not work for recharging (the CORE sensor only requires a small amount of power and it may be too small to trigger / wake-up the USB battery packs).

When the CORE sensor has power and connects to power, it will blink rapidly 5 times and while charging blinks once per second. When charging is complete, it stops blinking.

If the CORE sensor battery is completely empty, when connected to a power source it will take up to 30 seconds for it to have enough charge and begin blinking.

To preserve the battery life, it is recommended to recharge before the battery is completely empty

Default Battery Mode

By default, the CORE sensor is always on, even when it is not being worn. The battery life is over 6 days.

Standby Battery Mode

The current firmware (0.6.0 or newer) and CORE phone app (1.3.5 or newer) support Standy mode. This can be enabled inside the CORE App settings for the CORE sensor.

When standby mode is enabled, CORE will automatically enter a low power state after it has not been worn for 20 minutes.

During standby mode, all data communication is disabled.

Standby mode can extend the time between recharges to up to 1 month though this will depend how often the CORE sensor is used. .

Wake your CORE from standby mode by shaking the CORE, connecting it to a charger, or resetting it.

CORE App and CORE Sensor information

Inside the CORE App, the on-screen information will show the battery charge, whether it is connected to a heart rate monitor and if it is download data.

The CORE sensor can be shaken and the green LED light will also provide indications and the following describes the LED behaviour and meaning.

LED Behaviour

When the CORE sensor is shaken or connects, the green LED light blinks to provide indications for:

• Battery level and heart rate monitor detected • Charging Status
• CORE connects to a paired device (4x rapid blink)
• CORE App downloading data (continual fast blinking)
• CORE sensor reset

LED - Battery Level

When you shake your CORE to wake it from standby, the LED indicates how much battery is left.

LED - Heart Rate Monitor connection

Following the battery status, the CORE sensor will also blink (for 2 minutes) to indicate if a heart rate monitor is currently paired. This is important as a heart rate monitor is recommended for sports-use to increase the level of accuracy:

• No Heart Rate Monitor detected: single blink every 2 seconds (everyday living mode)

• Heat Rate Monitor connected: double blink every 2 seconds (sports mode)

LED - Charging & Connection Status

• Currently Charging: LED blinks 1 second on and 1 second off
• Charge complete: LED off
• Connected to USB: Blinks 5x
• Paired device connects to CORE: Blinks 4x
• CORE App Downloading Data: Blinks continuously while downloading
• CORE App Reset: Short blink followed by battery level

CORE and battery disposal

The CORE sensor and the battery has a lifespan that is impacted by the level of care and charging. The battery life will naturally degrade over time and at the end of the lifetime, the complete CORE sensor can be disposed of in battery recycling.

Battery Safety Instructions

The following precautions are necessary to ensure safety when using and storing the CORE sensor:

• replacement of the battery with an incorrect type that can defeat a safeguard (for example, in the case of some lithium battery types);
• disposal of a battery into fire or a hot oven, or mechanically crushing or cutting of a battery, that can result in an explosion;
• leaving a battery in an extremely high temperature surrounding environment that can result in an explosion or the leakage of flammable liquid or gas; and
• a battery subjected to extremely low air pressure that may result in an explosion or the leakage of flammable liquid or gas.
