CONNECTING POWER

You can power your calculator from either four AA batteries or an external
AC power adapter (not supplied).  If you plan to use the print function
frequently, we suggest you use an AC adapter.

Installing Batteries

You can power your calculator from four batteries.  For the longest life,
we recommend you use alkaline batteries, such as Radio Shack Cat. No.
23-552.

1.  Slide the battery compartment cover in the direction of the arrow and
    lift up the cover.

2.  Place four fresh AA batteries in the compartment as indicated by the
    polarity symbols (+ and-) marked inside the compartment.

3.  Replace the cover.

Connecting an AC adapter

You can power your calculator from standard AC power, using an AC adapter,
such as Cat. No. 273-1650 (not supplied).

CAUTION:  Use only an AC adapter that supplies regulated 6 volts and
          delivers at least 300 milliamps.  Its plug must correctly fit the
          calculator's DC 6V jack and its center tip must be set to
          positive.

1.  Turn off the calculator by setting P/NP/OFF to OFF.

2.  Plug the adapter's barrel plug into the jack on the back of the
    calculator.

3.  Plug the adapter's power module into a standard AC outlet.

NOTE:  The EC-3030 automatically disconnects the internal batteries when
       an AC adapter is connected.

INSTALLING THE PAPER ROLL

1.  Remove the printer cover by pushing it in the direction of the arrow.

2.  Install the paper holders by inserting their hooks into the slots on
    the calculator's back housing.

3.  Insert the knob on each paper holder into the ends of the paper roll.
    The edge of the paper should feed from underneath the paper roll.

4.  Insert the edge of the paper firmly into the slot underneath the tab.

5.  Set P/NP/OFF to P or NP, then press UP ARROW so the paper feeds
    through the calculator.

6.  Replace the printer cover.

Replace the paper roll when you see a red strip on one edge of the paper.
We recommend you use Radio Shack Cat. No. 65-710
