Using AC Power
To power the CTR-108 from standard
AC power, plug the supplied power
cord into the
AC IN
jack on the side of
the CTR-108. Then plug the other end
into a standard AC outlet.
Cautions:
• Always plug the power cord into
the
AC IN
jack before you plug it
into the AC outlet, and always
unplug the power cord from the
AC outlet before you unplug it
from the
AC IN
jack.
• The power cord has a polarized
plug that is designed to fit into the
recorder’s jack only one way. If the
plug does not easily fit into the
jack, do not force it. Simply turn it
over and try again.
Using Vehicle Battery Power
You can power the CTR-108 from your
vehicle’s cigarette-lighter socket using
a DC adapter, such as Cat. No. 273-
1802 (not supplied).
Cautions:
• You must use a DC adapter that
supplies 6 volts and delivers at
least 300 milliamps. Its center tip
must be set to negative, and its
plug must correctly fit the CTR-
108’s
DC IN 6V
jack. The recom-
mended adapter meets these
specifications. Using an adapter
that does not could damage the
CTR-108 or the adapter.
• Always plug the adapter into the
CTR-108 before you plug it into
the cigarette-lighter socket, and
always unplug the adapter from
the cigarette-lighter socket before
you unplug it from the CTR-108.
1. Set the DC adapter’s voltage
switch to 6V.
2. Insert the adapter’s barrel plug
into the CTR-108’s
DC IN 6V
jack.
3. Insert the adapter’s larger plug
into the vehicle’s cigarette-lighter
socket.
