• If you do not plan to use the
CTR-110 from battery power for
a month or more, or if you plan
to use only an adapter, remove
the batteries to protect the CTR-
110 from possible battery leak-
age.
Using AC Power
You can power the CTR-110 from
standard AC power using an optional
AC adapter, such as RadioShack
Cat. No. 273-1663.
Cautions:
• The recommended AC adapter
supplies 6 volts and delivers at
least 400 milliamps. Its center tip
is set to negative, and its plug
correctly fits the CTR-110’s
DC
6V
jack. Using an AC adapter
that does not meet these specifi-
cations could damage the CTR-
110 or the adapter.
• Always plug the adapter into the
CTR-110 before you plug it into
the AC outlet, and always
unplug the adapter from the AC
outlet before you unplug it from
the CTR-110.
1. Set the AC adapter’s voltage
switch to 6V.
2. Insert the AC adapter’s 5.5 mm
outer diameter/2.1 mm inner
diameter barrel plug into the
adapter cord’s small end so it
reads –TIP, then insert the
adapter’s plug into the
DC 6V
jack on the back of the CTR-110.
3. Plug the adapter into a standard
AC outlet.
Using Vehicle Power
You can power the CTR-110 from
your vehicle’s battery using an op-
tional DC adapter, such as Ra-
dioShack Cat. No. 273-1802.
Cautions:
• The recommended DC adapter
supplies 6 volts and delivers at
least 400 milliamps. Its center tip
is set to negative, and its plug
correctly fits the CTR-110’s
DC
6V
jack. Using a DC adapter that
does not meet these specifica-
tions could damage the CTR-
110 or the adapter.
