My M430 is not charging
Please note that if the battery is completely empty, it takes a couple of minutes for the charging to start. If your M430 won't charge, follow the troubleshooting steps below.
Do not charge the device when the USB port is wet.
If your M430 doesn’t charge properly, or if it doesn’t connect to FlowSync, it could be because the charging area on the back of the product is not clean enough.
Before charging, make sure there’s no moisture, hair, dust or dirt on the M430’s USB port or charging cable. Gently wipe off any dirt and blow off any dust. You can use a toothpick if needed. Do not use any sharp tools for cleaning to avoid scratching.
Keep the USB port clean to effectively protect your M430 from oxidation and other possible damage caused by dirt and salt water (e.g. sweat or sea water). The best way to keep the USB port clean is to rinse it after each training session with lukewarm tap water. The USB port is water resistant and you can rinse it under running water without damaging the electronic components. Do not charge the device when the USB port is wet.
- Make sure the USB connector is firmly in place.
- Remove and replug the USB cable into your M430.
- If you plugged your M430 into your computer via USB Hub, try plugging it in directly to the computer's own USB port.
- Try the other USB port(s).
