BATTERY maintenance and
precautions
Battery capacity deteriorates over time. To opti-
mize battery life time:
• Charge battery prior to becoming com-
pletely empty.
• Do not expose the battery to heat longer
than necessary (above 30°C is considered
hot).
• Disconnect charger as soon as possible
after battery becoming fully charged.
• Especially do not leave battery flat as it
may harm the battery.
• EVEN IF THE DEVICE IS NOT USED FOR A
LONGER PERIOD IT'S RECOMMENDED TO
CHARGE THE BATTERY AT LEAST EVERY
THREE MONTHS
