CONNECTING AN
EXTERNAL ANTENNA
For Better AM Reception:
Your radio has a built-in AM antenna
for reception of strong, local broadcasts. For improved reception, you
can connect an external AM antenna.
Your local RadioShack store has a
wide selection of AM antennas.
For Better FM Reception:
Your radio has a telescoping antenna
for FM reception.
Note: When you use the telescoping
antenna for FM reception, be sure the
metal strap is connected as shown.
To connect an external AM antenna to
your radio, use a Phillips screwdriver
to loosen the screw on the external
antenna terminal, slide the external
antenna’s spade lugs underneath the
screw head, then tighten the screw.
For improved reception, you can connect an external FM antenna. Your local RadioShack store has a wide
selection of FM antennas.
Follow these steps to connect an external FM antenna to your radio.
1. Use a Phillips screwdriver to
loosen the screws on the external
antenna terminals.
• For an FM 75-ohm cable:

• For an FM 300-ohm cable:
2. Set BAND to FM or AM.
3. Rotate the tuning knob to select
the desired station.
2. Slide the external antenna’s
spade lugs underneath the screw
heads, then tighten the screws.
Note: When you attach an external FM antenna, be sure the metal
strap under the screw head connecting the telescoping antenna is
positioned correctly.
Notes:
OPERATING THE RADIO
Warning: To protect your hearing,
turn VOLUME to its lowest setting before you turn on the radio.
1. Push in POWER to ON.
• To precisely tune to a weak FM
station using automatic frequency control, slide AFC to
OFF. Rotate the tuning knob to
select the desired station, then
slide AFC to ON for drift-free reception.
• To get better audio fidelity when
selecting a strong station, slide
BANDWIDTH to WIDE. If you
hear whistling noises, slide
BANDWIDTH to NORMAL to get
better selectivity.

12-603.fm Page 5 Monday, January 24, 2000 12:29 PM
• For the best FM reception, extend the telescoping antenna to
its full length.
• For AM stations, rotate the radio to the position that provides
the best reception.
4. Adjust VOLUME, BASS, and TREBLE for the best sound.
5. To turn off the radio, push POWER
to OFF.
Using an Earphone
For private listening, plug a monaural
1
earphone (not supplied) with a /8-inch
plug into the EAR jack on the right of
the radio. This automatically disconnects the built-in speaker.
Listening Safely
To protect your hearing, follow these
guidelines when you use an earphone.
• Set the volume to the lowest level
before you begin listening. After
you begin listening, adjust the volume to a comfortable listening level.
• Do not listen at extremely high volume levels. Extended high-volume
listening can lead to permanent
hearing loss.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a volume level that does not cause discomfort might still damage your
hearing.
Traffic Safety
Do not wear an earphone while operating a motor vehicle or riding a bicycle. This can cause a traffic hazard
and is illegal in some areas.
Your local RadioShack store carries a
wide selection of earphones.
Even though some earphones let you
hear outside sounds when listening at
normal volume levels, they still can
present a traffic hazard.

CARE AND
MAINTENANCE
Your Optimus AM•FM Portable Radio
is an example of superior design and
craftsmanship. The following suggestions will help you care for the radio so
you can enjoy it for years.
• Keep the radio dry. If it gets wet,
wipe it dry immediately. Liquids
might contain minerals that can
corrode the electronic circuits.
• Use and store the radio only in
normal
temperature
environments. Temperature extremes can
shorten the life of electronic devices, damage batteries, and distort
or melt plastic parts.
• Keep the radio away from dust
and dirt, which can cause premature wear of parts.
• Handle the radio gently and carefully. Dropping it can damage circuit boards and cases and can
cause the radio to work improperly.
• Use only fresh batteries of the required size and type. Old batteries
can leak chemicals that damage
your radio’s electronic parts.
• Wipe the radio with a damp cloth
occasionally to keep it looking
new. Do not use harsh chemicals,
cleaning solvents, or strong detergents to clean the radio.
6
Modifying or tampering with the radio’s
internal components can cause a malfunction and might invalidate your radio’s warranty and void your FCC
authorization to operate it. If your radio
is not performing as it should, take it to
your local RadioShack store for assistance.
The FCC Wants You to Know
Your radio might cause TV or radio interference even when it is operating
properly. To determine whether your
radio is causing interference, turn it
off. If the interference goes away, your
radio is causing it. Try to eliminate the
interference by:
• Moving your radio away from the
receiver
• Connecting your radio to an outlet
that is on a different electrical circuit from the receiver
• Contacting a radio/TV technician
or your local RadioShack store for
help
If you cannot eliminate the interference, the FCC requires that you stop
using your radio.
