G Charging The Built-In Battery; Direct Charging From The Ac Adapter - Toshiba gigabeat F60 Owner's Manual

Charging the Built-in Battery
When the AC adapter is connected to the gigabeat, charging starts automatically.
If you are using the gigabeat for the first time after purchase, or when the
gigabeat hasn't been used for a prolonged period, fully charge the battery
beforehand.
One charging method is to connect the AC adapter directly to the gigabeat,
another method is to use the USB CRADLE (which is an option with the
MEGF20). Note that a USB connection with the PC will also permit charging.
G Preparation
Set the BATTERY switch on the bottom of the main unit to ON.
This switch prevents over-discharge of the built-in battery after shipment.
Set the BATTERY switch to ON the first time the gigabeat is used after purchasing it.
If you will not be using the gigabeat for a prolonged period, set the BATTERY switch to
OFF.
Setting the BATTERY switch to OFF will return all of the settings to their default
values (which is the condition when the gigabeat was first used after purchasing
it).
