CTR-88  (140-1103)               Power                 Faxback Doc. # 6210

With the proper adapter, you can operate the recorder from an AC outlet
or vehicle's cigarette-lighter socket.

AC/DC Adapter Notes:

You must use an adapter that supplies 3 volts DC power and delivers at
least 200 milliamps.  Its center tip must be set to negative, and it
must have a plug that properly fits the CTR-88's DC 3V jack.  Using an
adapter that does not meet these specifications could damage the CTR-88
or the adapter.

Connecting an AC or DC adapter automatically disconnects the internal
batteries.

Always plug the adapter into the recorder before you plug it into the
wall outlet or cigarette-lighter socket.  Always unplug the adapter from
the wall outlet or cigarette-lighter socket before you unplug it from
the recorder.

USING AC POWER

To power the recorder from an AC outlet, you need an AC adapter (not
supplied), such as Cat. No. 273-1654.

Insert the adapter's small plug into the recorder's DC 3V jack.  This 
disconnects the internal batteries.  Then plug the adapter into a standard
AC outlet.

USING THE VEHICLE'S BATTERY

You can power the recorder from your vehicle's cigarette-lighter socket.
This connection requires a DC adapter, such as Cat. No. 270-1560.

Caution: The vehicle must have a 12-volt DC, negative-ground electrical
         system.

Follow these steps to power the recorder from you vehicle's
cigarette-lighter socket.

1.  Set the adapter's voltage switch to 3V

2.  Attach the orange-rimmed barrel plug to the DC adapter's cord with
    the tip set to negative (-).

3.  Insert the plug into the recorder's DC 3V jack.  This disconnects
    the internal batteries.

4.  Plug the adapter into the vehicle's cigarette-lighter socket.

NOTE:  If the recorder does not operate properly when powered from the
       vehicle's battery, unplug the adapter from the cigarette-lighter
       socket and clean any ashes or other debris from the socket.
