Heel2Toe™ light (LED) guide

What the lights on your sensor are telling you

Start here

Your Heel2Toe has two lights

Knowing which one you are looking at answers most questions straight away.

Heel2Toe sensor plugged in with a USB-C cable, the charging light glowing red

Charging light

Shows charging status when the device is plugged in with the USB-C cable.

Heel2Toe sensor with the round operating light on top glowing green

Operating light

The round light on top. Shows what the device is doing.

Most asked

While you are walking

Every few seconds the operating light gives a short pulse to show status.

Green All good — right foot
Orange All good — left foot
Blue Working, but the beep is switched off
Purple Not calibrated yet, or no memory card
Yellow Battery low — charge soon
Red Battery critically low

Remember: it is the beep, not the light, that tells you when you have made a good step.

After you press record

Calibrating

Stand still. The light holds a steady colour to confirm which foot it is set for.

Purple Right foot
Orange Left foot
Pink Auto Foot Detect — it works out your foot from your first steps

You will hear four short beeps and one long beep when calibration is complete. With Auto Foot Detect, after your first steps the light turns green for right or orange for left.

Switching on and connecting

Start-up, charging and docking

Red Charging light: the device is charging
No light Charging light: fully charged
Blue, green, red Normal start-up check when you switch the device on. A single white flash means a memory card is fitted.
Blinking blue Docking mode — the device is talking to the Docking Station app and will not record. To enter it, plug the device in and switch it off and back on.

Something is wrong
