Setting The MW (AM) Tuning Increment

In the United States, the Federal Communications Commission (FCC) assigns
frequencies for stations in the MW band in 10-kilohertz increments.  (In
the United States, we commonly call the MW band the AM band.) In Europe and
some other parts of the world, MW frequencies are assigned in 9-kilohertz
increments.

The MW STEP switch is located inside the battery compartment.  Before you
install the back-up batteries, set the switch to 9k or 10k using the follow-
ing guidelines:  If you are in the United States, Canada or another North or
                 South American country, be sure the switch is set to 10k.

                 If you are in a country where the AM frequency increments
                 are 9 kHz, set the switch to 9k.

Installing Back-Up Batteries

Back-up batteries power the receiver's clock and the display and save the
stations stored in memory if the receiver's primary power source is inter-
rupted.

The receiver uses three AA batteries for back-up power.  For best perform-
ance, we recommend alkaline batteries, such as Radio Shack Cat. No. 23-552.

NOTE:  You cannot operate the receiver using only the back-up batteries. If
       you press POWER when the back-up batteries are the only available
       power source, E flashes on the display.

Follow these steps to install the back-up batteries.

1.  Remove the battery compartment's cover by pushing the cover in the
    direction of the arrow.

2.  Install three AA batteries, according to the polarity symbols (+ and -)
    marked next to the compartment.  For easy removal, place the batteries
    on top of the lift-out ribbon.

3.  Replace the cover, or install additional batteries for primary power as
    described in "Internal Battery Power".

To check the back-up batteries' power level, disconnect the receiver from
the primary-power source.  Then look at the receiver's display.  If it is
dim, replace the back-up batteries.

Connecting To Primary Power

You can power the receiver from internal batteries, standard AC power, or
your vehicle's battery.

Internal Batteries

Your receiver uses four D batteries.  For best performance, we recommend
alkaline batteries, such as Radio Shack Cat. No. 23-550.

Follow these steps to install batteries for use as the primary power source.

1.  Remove the battery compartment's cover by pushing the cover in the
    direction of the arrow.

2.  Slide four D batteries into the compartment, according to the polarity
    symbols (+ and -) marked next to the compartment.  For easy removal,
    place the batteries on top of the lift-out ribbon.

3.  Replace the cover.

To check the primary-power batteries, turn off the receiver.  The battery
power indicator appears on the display for several seconds. Fresh batteries
show a power level of 7.  If the indicator shows a power level of 2 or
below, replace the primary-power batteries.

NOTE:  If you  press RADIO POWER to turn on the receiver when the primary-
       power batteries are dead, E flashes on the display if back-up batt-
       eries are installed.

AC Power

With an optional AC adapter, such as Radio Shack Cat. No. 273-1655, you can
power the receiver from standard AC power.

CAUTION:  You must use an AC adapter that supplies 6 volts with the center
          tip set to negative.  It must deliver at least 500 milliamps, and
          its plug must properly fit the receiver's DC IN 6V jack. Using an
          adapter that does not meet these specifications could damage the
          receiver or the adapter.

Follow these steps to use AC power.

1.  Set the adapter's voltage switch to 6V.

2.  Line up TIP on the green-tipped barrel plug with -NEG on the adapter's
    socket, and insert the plug.

3.  Insert the barrel plug's other end into the receiver's DC IN 6V jack.

4.  Plug the adapter into a standard AC outlet.

NOTE:  Using an adapter disconnects the primary-power batteries.

DC Power

With an optional DC adapter, such as Radio Shack Cat. No. 14-844, you can
power the receiver from your vehicle's battery.

CAUTIONS:  You must use a DC adapter that supplies 6 volts with the center
           tip set to negative. It must deliver at least 500 milliamps, and
           its plug must properly fit the receiver's DC IN 6V jack.  Using
           an adapter that does not meet these specifications could damage
           the receiver or the adapter.

           Your vehicle must have a 12-volt DC, negative-ground electrical
           system.

           To protect your vehicle's electrical system, be sure the adapter
           is connected to the cigarette-lighter socket only when it is also
           connected to the receiver.

Follow these steps to use DC power.

1.  Set the adapter's voltage switch to 6V.

2.  Insert the adapter's barrel plug into the receiver's DC IN 6V jack.

3.  Insert the adapter's large plug into the vehicle's cigarette-lighter
    socket.

4.  Insert the adapter's plug into the vehichle's cigarette-lighter socket.

NOTE:  Using an adapter disconnects the primary-power batteries.

Using The Folding Stand and Memo Pad

You can position the receiver more securely and possibly improve the sound
by resting the receiver on its stand.

Lift the latch on the back of the receiver to open the stand.  You can use
the memo pad under the receiver's stand to record helpful information, such
as the memory location numbers of your favorite stations.
