Troubleshooting

Possible Causes:

• Device is in ship mode (after storage or shipping)
• Battery is completely drained
• Hardware malfunction

Solutions:

1. Hold the left button for about a second (up to 3 seconds) — this wakes the device from ship mode
2. Place on the charging dock for at least 30 minutes
3. Check if the charging screen appears while docked
4. Ensure proper alignment on the dock
5. Contact support if issue persists

Possible Causes:

• Long sessions in sound or vibration mode
• Screen brightness or volume set high

Solutions:

1. Use LED mode for the longest sessions (20+ hours vs ~7 hours with sound, ~9 hours with vibration)
2. Reduce screen brightness and volume in settings
3. For storage, use Device → Ship mode — the idle auto power-off protects the battery day to day
4. Check for firmware updates that may improve battery life

Symptoms: Device keeps restarting when powered on

Solutions:

1. Disconnect from charger
2. Perform a hard reboot: hold the left button for more than 10 seconds — the device power-cycles
3. If the problem returns, perform a factory reset (hold middle + right buttons for 10 seconds and confirm)
4. If problem persists, contact support

Solutions:

1. Press any button to wake the screen — it dims and sleeps automatically to save power
2. Adjust brightness in Settings → Brightness
3. Note that during training the screen sleeps on purpose; the beat keeps running

Solutions:

1. Perform a hard reboot: hold the left button for more than 10 seconds
2. Update firmware via mobile app
3. As a last resort, perform a factory reset (middle + right for 10 seconds and confirm — this restores default settings)

Solutions:

1. Power cycle the device (hold left 3 seconds → power off, then wake again)
2. Check if buttons are physically damaged
3. Contact support if hardware issue suspected

Solutions:

1. Keep the button fully pressed and held — don't release between steps
2. Fast scrolling works on value screens (tempo, volume, brightness), not in menus

Solutions:

1. Ensure Bluetooth is enabled on mobile device
2. Restart both devices
3. Delete old pairings — on the phone and via Connect → Bluetooth → Unpair on the device
4. Update mobile app to latest version
5. Check device is within range (10 meters)

Solutions:

1. Verify the strap supports Bluetooth (BLE) — ANT+-only sensors are not supported yet
2. Check the strap battery level
3. Wear the strap so it's actively measuring (moisten the electrodes)
4. Reduce distance between devices (3-5 meters)
5. Retry from Connect → Heart Rate

Symptoms: Device resets to default settings after power off

Solutions:

1. Wait a few seconds after changing a setting before powering off — settings are saved shortly after the last change
2. Update firmware
3. Contact support if issue persists

Solutions:

1. Ensure device has at least 50% battery
2. Keep device close to phone during update
3. Ensure stable Bluetooth connection
4. Place the device on its charging dock during the update
5. Contact support for manual update

Solutions:

1. Perform a hard reboot: hold the left button for more than 10 seconds — the device power-cycles
2. Update firmware if available
3. If freezes keep coming back, perform a factory reset (hold middle + right buttons for 10 seconds and confirm)
4. Contact support if problem continues

Solutions:

1. Open a program from the Training menu first, then press the middle button to start
2. Verify the tempo is set
3. Try restarting the device

Solutions:

1. Verify tempo setting on display
2. Check which program is running — Interval, Pace, and Waltz behave differently from plain Tempo
3. Reset to default (1.30s) and test

Symptoms: Device stops working after water exposure

Solutions:

1. Immediately power off device
2. Dry thoroughly (do not use heat)
3. Wait 24-48 hours before attempting to power on
4. Contact support for warranty claim if needed

Solutions:

1. Check warranty status
2. Contact support for repair options
3. Do not attempt to open device (voids warranty)
