D cells, all of the same brand and type. To prevent battery acid leakage, follow these instructions. Battery acid leakage is not covered by
the radio’s warranty. Never install or replace with batteries of dierent
brands and types. Never intermix old batteries with new ones. When
not using the radio for more than 30 days, remove the batteries.
USING BATTERIES
Use 6 D size alkaline batteries. Install them with correct polarity using the diagram inside the battery compartment on the back of the
radio. Replace them if the battery strength indicator in the display
shows one bar or the sound becomes distorted. The radio will turn
o automatically if the batteries become too weak.
BATTERY LEVEL INDICATOR
The battery level indicator is in the upper left corner of the display.
When batteries are full, “

USING AC POWER
Plug AC adapter into the socket on the left side of the radio. Use
only the AC adapter supplied. When the AC adapter is plugged in,
the full power level will show in the upper left corner of the display,
looking like a full battery. If you lose the AC adapter that came with
the radio, use one with 9 Volt DC output, negative polarity, 500
milliampere and a plug with 5.5 millimeter outer diameter, 2.1
millimeter inner diameter.
POWERING FROM A CAR OR BOAT
Use a DC to DC converter. Output: 9 Volt DC, negative polarity, outer
diameter 5.5 millimeter; inner diameter 2.1 millimeter.
TURNING ON AND OFF / SETTING AND
DEACTIVATING THE SLEEP TIMER

TUNING IN FM STATIONS
The FM frequency range is from 87.5 to 108 MHz.
Fully extend the telescopic antenna and turn on the radio. •
Place the top BANDWIDTH control onto the MONO or STEREO •
position. Stereo is needed only when you’re using headphones and
STEREO appears above the top left of the frequency in the display.
FM mono has better signal and noise ratio as well as anti-multiplex
interference.
Tune in the station with the TUNING knob or by pressing the UP/•
DOWN button or by pressing and holding the UP/DOWN button for
one second to engage auto tuning.
BASS/TREBLE KNOBS
Use these knobs to control the bass and treble response of the radio’s

When listening to AM (MW) broadcast stations, this control knob
should be dialed to or near position 5. If you are listening to a weak
station, increase the gain, when listening to extremely strong stations,
decrease the gain. For listening to Shortwave stations, place this
control to maximum gain and decrease the gain as necessary.

TUNING IN MW STATIONS (AM);
CHANGING THE TUNING STEPS
MW, or medium wave stations, known as AM stations, range from
une in 9 KHz steps and in other parts of the world they may tune
in 10 KHz steps. The radio is set up for 9 KHz tuning by default, but
to change the steps to 10 KHz, go into the battery compartment and
move the switch from 9 KHz to 10 KHz and then press the reset
button with a paper clip. The switch is located on the middle of the
ridge between the upper set and lower set of batteries.
Turn on the radio. 1.
Place the top BANDWIDTH switch into the W or N position (wide or 2.
narrow). Place bottom BANDWIDTH switch into the MW position.
Place AM/SW RF GAIN switch into the 5 position, higher if necessary. 3.
Tune in the station with the TUNING knob or by pressing the UP/4.
DOWN button or by pressing and holding the UP/DOWN button for
one second to engage auto tuning.
Use WIDE if no interference is present. Use NARROW if
interference is present.

TUNING TO SW FREQUENCY RANGES (BANDS)
Tune to these frequency ranges for best results. The radio can also
tune between these ranges.
Meter Band (m) Frequency Best Time of Day
90m 3,200-3,400 kHz
75m 3,900-4,000 kHz
60m 4,750-5,050 kHz night

OPTIMIZING SHORTWAVE RECEPTION
Shortwave enables listening to broadcasts over vast distances including
other countries and continents. The following information will help you
get the best results.
• During the day, frequencies above 13 MHz are usually best.
• At night, frequencies below 13 MHz are usually best.
• Around sunset and sunrise, the entire shortwave range may be good.
• Getting very close to a window and holding the radio improves
shortwave reception.
STORING AND RETRIEVING STATIONS INTO
AND FROM PRESETS (MEMORIES)
Tune to the station that you want to store. Press and release the T.SET
button and see ‘Preset’ with a number underneath it flash in the right
