Getting Started About power management The Reader has a power management feature to avoid unnecessary battery consumption. At purchase, power management is activated. Power management operates as follows: After 60 minutes of inactivity, the Reader enters sleep mode automatically while the battery power is consumed slightly. After 5 days of inactivity, the Reader automatically shuts down and stops consuming the battery power. If the battery power is at a low level, the Reader will shut down after 60 minutes of inactivity. Hints You can activate/deactivate power management from "Power Management" in the "Settings" menu ( page 154). In addition to power management feature, you can save the battery power using "Wireless Standby" ( page 35, 155). Notes The Reader does not enter sleep mode after 60 minutes of inactivity even if "Power Management" is set to "On," when: - connected to the computer using the supplied USB cable - connected to an AC outlet - playing audio files or a slideshow The Reader does not wake up from sleep mode when receiving periodicals by auto delivery ( page 40). Therefore, if other operations are not performed for 5 days, the Reader will automatically shut down by power management. Continued 20
