IMPORTANT Notes while charging your Reader device:

  • It is recommended to charge the Reader™ Digital Book  using the supplied AC Adapter. When using the AC adapter to charge your Reader device, the lightning bolt symbol that appears next to the battery icon [FIG. 1] on the display of your Reader device is an indication that it is connected to AC power and is charging the battery properly. If the lightning bolt symbol is not present, double check the AC Adapter to ensure that your Reader device is properly connected. This symbol does not appear while charging via a USB connection.
  • If you charge via a USB connection and leave your Reader Digital Book connected to the computer to charge and the computer goes into sleep/hibernation, charging will stop and the red charge indicator on the Reader will turn off. If left connected, your battery may begin to discharge. To avoid this, turn off any sleep/hibernation settings while charging or set your sleep or hibernation settings to come on after your Reader Digital Book has been charged and then disconnect it from the computer once charging has completed.
  • It will take approximately 4 hours to achieve a full charge with a computer. It will take approximately 2 hours to achieve a full charge with the optional AC Adapter.
  • If your Reader Digital Book is left connected to a powered USB hub while the computer is shut down, your battery may begin to discharge. Disconnect your Reader from the hub when the computer is not powered on.
  • Always verify that your Reader is fully charged by disconnecting it from the computer and checking the battery indicator. The battery indicator will display 4 black bars when it is fully charged

On a full charge, the battery has the capability of up to 7,500 continuous page turns. Actual battery life will vary based on usage patterns, settings and battery conditions. When the Reader is turned on, off, or a page is marked, battery power is used, thus lowering the expected battery life.

NOTE: When storing the Reader for a long period of time, use the Device Shutdown feature in the Advanced settings menu. After using Device Shutdown, it may take approximately 30 seconds for the Reader to start the next time the Reader is turned on.

Playing audio will reduce the battery life. If you did not start audio play back intentionally, confirm audio is not playing. You will not hear playback unless headphones are connected. Audio playback will continue until it is stopped by turning it off from the Now Playing menu. To see if audio is playing, press the HOME button and then press the OPTION button. If Now Playing is displayed in the dialogue box that appears, tap Now Playing and this will take you to the song that is playing. Press the Pause button to stop playback of that song and then press the HOME button.

NOTES:

  • Due to the nature of the E Ink electronic display technology, the LCD can retain an image without having power. Turning the page is the only time power is consumed. If the Reader's power is drained, the LCD will retain the last image that was displayed, thus making it appear like the Reader is frozen and in some instances it will not have enough power to perform other operations such as turning on or off.
  • Battery life can be affected by operating temperatures below 41 degrees F, lack of use, or if the battery has not been given enough time to fully charge.
  • As with any battery, if the Reader is stored for an extended period of time, the battery will discharge on it's own. Therefore, it may be necessary to charge the battery prior to use.
  • If the Reader has not been used for an extended period of time, repeatedly charging and discharging will improve the efficiency of the battery.
  • If the battery life still seems short, the battery may need to be replaced.
