Using the battery
Remove the AC adapter. Switch the ON/OFF switch to the ON
position. If the battery is charged, it will power the unit.
2. Charging
A built-in rechargeable battery (Ni-MH) is included for portable use.
A fully charged battery will provide about 2 hours of playtime.
Note: Charge the battery for at least 8 hours before you use it for
the first time.
1) Switch the ON/OFF switch to the OFF position.
2) Connect one end of the AC adapter to the DC jack and the other
end to a 120VAC standard wall outlet. The red charge indicator
will light. Once the battery is fully recharged, the red light will turn
off.
3) Disconnect the AC adapter.
Note: It takes about 5 hours to charge the battery after its initial
charging.
