How do I maintain my M430 in the best possible condition?
Read the tips below to help you keep your M430 in good condition.
Keep your training device clean
Wash the M430 under running water with a mild soap and water solution after each training session. Wipe it dry with a soft towel before putting it back on.
Keeping the M430 clean and dry and loosening the wristband a bit after training helps your avoid any skin irritation.
Keep the device's USB port and charging cable clean to ensure smooth charging and syncing
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 M430 when the USB port is wet or sweaty.
Take good care of the optical heart rate sensor
Keep the optical sensor area on the back cover scratch-free. Scratches and dirt will reduce the performance of the wrist-based heart rate measurement.
