Attaching the head sensor

The sensor fastens to most headgear with hook-and-loop (Velcro®). Whatever you use, make sure the device cannot shift — loose sensor equals garbage data.

A permanent adhesive pad on the back lets you stick a hook strip in place; that strip then attaches to any loop surface (ACT headband, Dock, or your own gear). Think before you stick — the adhesive is one-way.

Mounting on a helmet? Read the helmet manual and use helmets that meet the correct safety standard. Remember: forces measured on the helmet shell are not identical to forces on the skull.

Important usage information

1. Android app required (free on Google Play; in-app purchases may come later). Check the FAQ for tested phones — some need manual scanning.
2. Grant Location permission and keep Bluetooth® enabled whenever the sensor is in use.
3. If your phone supports “Nearby Devices”, grant that permission too. If it lacks the feature, ignore this step.
4. Keep mobile data (or Wi-Fi) and a valid SIM/e-SIM active, or nothing syncs.
5. If passive scanning fails, use Active Scan (fine for solos, lousy for teams — see manual).
6. Practical range can drop below 10 m. During an incident, keep the phone close to the sensor.
7. The sensor shuts down after 180 minutes. For marathon sessions, power-cycle every three hours.
8. Cloud upload can eat mobile data any time the sensor is on. Kill Bluetooth® or mobile data if you don’t like that.
