Battery Charging
The Model Two has a built-in 3.6 V / 3.5 AH Ni-MH battery. When fully charged, it can be used for
over six hours. When the battery charge drops below 10%, the battery symbol flashes in the
information line at the top of the display screen. If the charge drops below 5%, the Model Two
shuts off automatically to protect the battery. You cannot turn the Model Two on again until you
recharge the battery.
To charge the Model Two’s battery, connect the charge cube to the charge socket on the bottom of
the Model Two (see
Identify Components
on Page 14) and plug the charger into an AC outlet.
While charging, the Model Two display indicates the charging mode with a charging curve and
displays an approximate percentage of charge. The elapsed charging time is also displayed. A full
charge will be achieved in less than 3 hours, after which the Model Two will shut off automatically.
