can
result
in
battery

PLEASE
NOTE:
AC/DC
adapters
are
very
different
from
AC/AC
adapters.
Manufacturers
commonly
abbreviate
and
refer
to
all
types
simply
as
"AC
Adapters",
which
gives
no
indication
of
their
actual
output.
Be
aware
that
most
adapters
are
in
fact
AC/DC
type,
which
supply
DC
current.
These
power
adapters
are
used
with
laptops,
game
consoles,
computer
peripherals,
etc.,
and
are
not
compatible
with
the
Objective2.
The
O2
strictly
requires
an
AC
‐
to
‐
AC
transformer,
with
minimum
14VAC
output.
Charging
Instructions
1.
Connect
an
AC
power
adapter
to
the
14
‐
20
VAC
Jack
,
then
connect
AC
adapter
to
wall.
Amplifier
can
be
used
simultaneously.
2.
Charge
time
for
included
NiMH
batteries
is
8
‐
24
hours
.
3.
O2
charges
indefinitely
at
a
low
current
(no
charge
status!).
Remove
