e Operate the unit only on 6 V DC.
For battery operation, use four size AA (R6) batteries.
For AC operation, use the AC power adaptor supplied with this
unit; do not use any other type.
For car battery operation, use the car battery cord recommended
for this unit; do not use any other type.
e Do not leave the unit in a location near heat sources, or in a place
subject to direct sunlight, excessive dust, or mechanical shock.
e Use the unit within a temperature range of 0°C to 40°C (32°F to
104°F). If it is used in temperatures outside this range, there may
be trouble with the frequency and clock display. If it is used in
temperatures lower than this range, the displayed numbers may
change very slowly. This is not an internal malfunction. The display
will recover when the unit is used within the recommended
temperature.
ə Should any solid object or liquid fall into the unit, remove the
batteries, and have the unit checked by qualified personnel before
operating it any further.
« Since a strong magnet is used for the speaker, keep personal
credit cards using magnetic coding or spring-wound watches away
from the unit to prevent them from possible damage caused by the
magnet.
e Reception around 1.8 MHz and 3.6 MHz may be difficult because
of internal spurious signals generated by the built-in oscillators.
e When the casing becomes soiled, clean it with a soft cloth
dampened with mild detergent solution. Never use abrasive
cleansers or chemical solvents, as they may mar the casing.
If you have any question or problem concerning your unit that is not
covered in this manual, please consult the nearest Sony dealer.

SSB (Single Side Band)
SSB is very popular among ham and business radio and will be
found on ali of the amateur bands because of its signal
intelligibility. This results from that it transmits signals with half
bandwidth of DSB (Double Side Band).
Typical AM (MW, LW, SW) band uses DSB. In DSB
transmission, the amplitude of a carrier is modulated according
to transmitted frequencies as shown below.
Amplitude
Amplitude Frequency
Audio signals are included both in USB and LSB. These signals
included in USB and LSB are the same ones except that they
are in the opposite phase relation.
This means that transmission can be done using only one of
USB and LSB. SSB transmission is the system in which such a
method is used. In general, SSB transmissions up to 10 MHz
shall employ LSB modulation, and those above this frequency
shall use USB. To receive SSB transmission, the unit with the
BFO (Beat Frequency Oscillator) circuits is needed to convert
SSB signals into audio signals. SSB cannot be heard with the
radio which has no such circuits.
CW (Continuous Wave)
CW is also popular among ham and business radio. In CW
transmission, the amplitude of a carrier is not modulated while
that of other systems is modulated. CW conveys information by
interrupting a carrier using Morse code. It can be heard as a
beat sound only with the unit equipped with the BFO circuits. To
understand information transmitted by CW, you need to learn
the Morse code.

Notes
e When receiving MW or LW broadcasts without an external antenna, be sure
to disconnect a SW external antenna. Otherwise, you cannot receive them
as the built-in ferrite bar antenna does not function.

disconnect its AC power adaptor (if connected) immediately.
+ When using an external antenna, retract the telescopic antenna.
* Locate an outdoor antenna as far away from the street as possible.
