Built-in Battery Care
• Your product is powered by a rechargeable battery.
• The battery can be charged and discharged
hundreds of times, but will eventually wear out.
• Unplug the charger from the electrical plug and the
product when not in use.
• Do not leave a fully charged battery connected to a
charger, since overcharging may shorten its lifetime.
• If left unused, a fully charged battery will lose its
charge over time.
• Leaving the product in hot or cold places, such as in a
closed car in the summer and winter conditions, will
reduce the capacity and lifetime of the battery.
• Always try to keep your device in a cool, moisture-
free environment that's less than 32°C. A product
with a hot or cold battery may not work temporarily,
even when the battery is fully charged. Battery
performance is particularly limited in temperatures
well below freezing.
