Under some
circumstances the
AC adapter may
be faintly audible
at close proximity.
The AC adapter is a highly efficient
Energy Star V adapter which is
required to operate at very low
audible duty cycles when
unloaded so as not to waste
energy.
There is no safety issue related to the faint
noise. In the event of a disconcerting
noise, disconnect the mains adapter from
the mains as soon as a battery charge is
complete.
The charge level
of the battery
drops when the
handheld is
turned off.
The handheld was left in Standby
mode or was left fully charged for
a long duration.
Before storing the handheld, completely
shut down the handheld (see Turning on
and turning off the handheld, page 20).
Then store the handheld as recommended
(see Storing the handheld, page 12).
