First you must use the rechargeable batteries. When the energy
is less than 20%, you should charge the batteries. Long time low
energy, the life of the batteries will be short. When charging, the
battery indication on LCD will flash. After charging fully, the
indication will stop flashing and show full. Don't charge for more
than 24 hours. If charging while using the device, the time will be
longer. The rechargeable batteries must be in device when you use
the AC/DC adaptor for charging. And do not charge the
non-rechargeable batteries, or the device will be destroyed and also
lose the guarantee.
