Notes
Charge the battery in an ambient temperature of between 5 to 35 ºC (41 to 95 ºF).
The number of t
imes the battery can be recharged before it is used up is approximately
500 times. This number may vary, depending on the conditions under which you use the
player.
The batter
y indicator on the display is only an estimate. For example, one section of
black in the indicator will not always indicate exactly one-fourth of the battery’s charge.
“Do not dis
connect.” appears in the display while the player accesses the computer. Do
not disconnect the supplied USB cable while “Do not disconnect.” appears or data being
transferred may be damaged.
The contro
l buttons on the player are all disabled while it is connected to a computer.
Some USB dev
ices connected to the computer may interfere with the proper operation
of the player.
We do not guara
ntee the recharge of the battery using personally assembled computers
or modified computers.
If the comp
uter enters a power saving mode, such as the sleep or hibernation mode,
while the player is connected via the USB cable, the player’s battery is not charged.
Instead, the player continues to draw power from the battery, discharging it.
Do not leav
e the player connected for extended periods to a laptop computer that is not
connected to AC power, because the player may discharge the computer’s battery.
While the pl
ayer is connected to a computer, do not turn on, restart, wake up from
sleep mode, or shut down the computer. These operations may cause the player to
malfunction. Disconnect the player from the computer before performing these
operations.
I
f you do not in
tend to use the player for over half a year, charge the battery at least once
per 6 to 12 months for the battery maintenance.
