Using AC Power

To power the CTR-109 from standard
AC power, plug the supplied power
cord into the 

AC IN

 jack on the side of

the CTR-109. 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-109 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 ,ust correctly fit the CTR-
109’s 

DC IN 6V

 jack. The recom-

mended adapter meets these
specifications. Using an adapter
that does not could damage the
CTR-109 or the adapter.

• Always plug the adapter into the

CTR-109 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-109.

Follow these steps to use vehicle bat-
tery power.

1. Set the DC adapter’s voltage

switch to 6V.

2. Insert the adapter’s barrel plug

into the CTR-109’s 

DC IN 6V 

jack.
