“Power Management”
Power management helps you to avoid unnecessary
battery consumption. “On” is set by default.
Power management operates as follows:
 After 60 minutes of inactivity, the Reader enters
sleep mode automatically and battery consumption is
minimized.
 After 5 days of inactivity, the Reader automatically
shuts down and stops consuming the battery power.
 If battery power is at a low level, the Reader will shut
down after 60 minutes of inactivity.
For details, refer to “About power management” (
page 20 )
Note
 The Reader does not enter sleep mode after 60 minutes of
inactivity even if “Power Management” is set to “On,” when:
– connected to a computer using the supplied USB cable
– connected to an AC outlet
– playing a track or slideshow
 The Reader does not wake up from sleep mode when
receiving periodicals. Therefore, if other operations are not
performed for 5 days, the Reader will automatically shut down
by power management.
