 After about 400 recharge cycles the ability for the battery to hold a charge will start to

diminish.

1.2.7 Recharging Battery

The battery will automatically recharge if needed whenever the player is plugged to AC power or a

computer. When the player is powered Off and plugged in, you will feel a double vibration if the

battery is recharging. The player can also be used while recharging. To obtain battery and recharge

status, press and hold the Confirm key. You can also obtain the battery and recharge status when

you press the INFO key (key 0). A full recharge takes up to 5 hours on AC power. Computers supply

different levels of power or perhaps no power at all on their USB ports depending on the computer

and its configuration. Therefore, when recharging from a computer USB, the Trek will likely take

longer to recharge, or possibly not recharge at all, depending on the USB power supplied by the

computer.

You may safely use a micro USB AC adapter other than the supplied power adapter. HumanWare

recommends a 1 amp USB power adapter. Adapters with less power will likely require more than 5

hours to fully recharge the battery.

When the player is operating on battery and left in pause mode for more than 30 minutes, it will

shut Off automatically to save the battery unless you are in Orientation mode and device has moved

within the last 30 minutes.

Important: It is normal for the battery to become warm during recharging. Therefore, it is

recommended not to charge the battery with the player near a heat source or within the optional

leather carrying case.

Note: The player's model and serial number can be found in the battery compartment. This same

information can also be obtained by pressing INFO (key 0).

1.2.8 NLS Book Cartridge (United States only)

Your Trek can play the special book cartridges supplied by the National Library Service for the Blind

and Physically Handicapped (NLS) in the United States providing you are eligible to receive NLS

books and your Trek has been authorized to play them. Please contact your local library for more

information on NLS service eligibility. The book cartridge is a USB flash device and can be played

on your Trek by connecting it to the micro USB port on the bottom edge of the player using the

included short USB cable.

1.2.9 Copying Books from USB Devices or NLS cartridges

You may copy DAISY or MP3 books from a USB flash device to the Trek’s SD card. You may also

copy books from a book cartridge used by the NLS in the United States. Connect the USB flash

device or NLS cartridge to the Trek using the short USB cable. To copy, press key 3 while the book

is playing or stopped. The progress of the copy operation will be announced regularly until the copy

is completed. This copying process can be cancelled at any time by pressing the Star key. If any

special character (\, /, :, *, <, >, |, .) is in the book title, it will be replaced by "_". You can play or

copy USB flash media only when the Trek is operating on battery power because the USB port

cannot be connected to a power outlet and the flash media at the same time, so be sure your

battery has a good charge before copying the USB book.
