Realistic PRO-37 - PREPARATION; POWER SOURCES; Important Information about External Adapters

PREPARATION
POWER SOURCES
You
can
power your
scanner
from any
of the
following three
sources:
.
lnternal
batteries
.
A
standard
AC
outlet
(using
an
op-
tionalAC
adapter)
.
Your
vehicle's battery
(using
an op-
tional
DC
adapter)
Using
Batteries
You
can
operate
your
scanner
from
six
AA
batteries.
For
longest
operation
and best
performance,
we recom-
mend alkaline
batteries
(Cat.
No.
23-
552). Or,
you
can use
rechargeable
nickel-cadmium
batteries
(Cat.
No.
23-125).
Warning:
The
scanner
has a
built-in
circuit
that
lets
you
recharge
nickel-
cadmium
batteries
inside the scanner.
However,
you
must
never use this
cir-
cuit
when
you
have
installed
non-re-
chargeable
batteries
in the scanner.
Be
sure
to
read
"lmportant

tion
about
External
AdaPters" and
"Charging
Nickel-Cadmium
Batteries."
