(AC) by use of standard three-pin plug (random
configuration). Before use, please check if the
voltage transfer switch (Figure 1) ⑪is consistent
with the alternating current (AC). When the voltage
transfer switch is at 115V position, it can adapt to
110 - 120V/60HZ alternating current (AC); when the
voltage is at 230V position, it can adapt to
220-240V/50HZ alternating current (AC); the
switch’s factory setting is 230V (Note: only adjust
under professional guidance)
Panel (Figure 2) ⑬is the power switch and
volume knob. By clockwise rotation, turn
the power on, and by counterclockwise
rotation, turn the power off. After power
on, continue to rotate to the right to
increase the volume to an appropriate
location (the volume knob is normally
adjusted to around ten o'clock direction).
Due to the use of vacuum tube amplifier,
vacuum tube needs about 30 seconds for
warming up before normal operation.
Therefore, the radio speaker will make a
sound 30 seconds later. Note that the
volume can’t be turned to the maximum
during these moments.

Radio use instructio ns
1
When the machine is used as a radio, it is of paramount
importance to place the machine and the external antenna
correctly. Otherwise, you may not receive any radio programs,
or only receive bad one! It is recommended to use the machine
close to window as much as possible. If it is impossible to use
the machine near the window, a group of external antennas will
be of great importance. The more professional the antenna and
antenna installation, the better the machine performance. In
addition, in case of connection with external antenna or not, it
should also be noted that the switch position for “internal/
external” antenna on the back of the machine must be correct!
Listen to FM broadcasting
This machine has equipped with built-in FM line. If the radio is placed
close to the window in the general urban area (not far from the radio
transmitting station), there is no need to use external antenna
generally. When external antenna (random accessory) is used, turn the
rear③(Figure 1) to the external (EXTERNAL) position. The external
antenna of this machine can also be connected with dedicated external
antenna or dedicated cable antenna. Press the (Figure 2) ⑯key switch
on the front of the machine to be in FM wave, and adjust the tuning
knob to the range of 87--108MHZ for its radio programs. Turn the
transfer switch (Figure 2) ⑫to FM position to be in ordinary FM state.
Turn to FM St position to be in stereo FM state. If the FM St effect is
not good enough, the switch can get a higher Signal to Noise Ratio
(SNR) at FM

Listen to medium wave broadcasting
Press (Figure 2) ⑲switch to be in medium wave band, and turn the knob
(Figure 2) ○
22 to listen to the radio programs within the range of
530-1610KHZ. This series of machine has high magnetic antenna. The AM
external antenna can also be used. Connect the two lines of the antenna to the
antenna clip, as shown in the figure below. Adjust the antenna to the best
direction, and then adjust the knob on the antenna (with external antenna for
tuning) to get the best signal. When the outdoor antenna is used, make
connection from (Figure 1) ①, and adjust the direction of external antenna to
get the clearest radio broadcasting.

Radio knowledge
①What is shortwave radio?
Many countries in the world use short frequency to perform worldwide broadcast transmission. Shortwave frequency
range is usually between 1.6MHz and 30MHz. The radio that can receive the frequency with the range is called
shortwave radio.
②What is “shortwave meter wave band”？
In general, we also divide the shortwave frequency into many "meter bands". Each meter band contains a frequency
range. For example, the 19M band contains a frequency range from 15.100 to 15.600MHz. The International Radio
Consultation Committee (CCIR) stipulates that the civil broadcaster uses the frequency within meter band range, and
the frequency beyond meter band is mostly used for military and other civilian communications. Therefore, the civil
broadcasting programs can only be received within the range of meter band frequency. (Please refer to the table
below)

Effect of listening to shortwave programs at different times of the day
What language programs can be received by
shortwave radios?
Shortwave signal propagation is subject to the influence of many factors, such as sunspot
activity, atmosphere and earth-ionosphere change. The shortwave propagation effect varies with
band, sometime good in the daytime or at night. It is not good to listen to shortwave program
during daytime, especially from 10 am to 3 pm. It is mainly because that shortwave is greatly
affected by the change of ionosphere in such period, leading to short transmission distance. If
you want to listen to shortwave programs during the daytime, please refer to the table above.
The effect may be good in certain meter bands, but inferior to that at night.
If in China, in shortwave radio programs, the Mandarin,
English, French, German, Russian, Japanese, Hindi,
Spanish, Portuguese, and other languages may be
heard, as well as our Cantonese, Teochew dialect,
Shanghai dialect, Minnan dialect and other dialects.
China's Central People's Broadcasting Station also uses
Mongolian, Uygur, Tibetan, Kazakh, Korean and other
minority languages for short-wave radio broadcasting.

What kind of radio
broadcasting can be received by
shortwave radio?
What content in the
shortwave program?
Is there the need to use outdoor external antenna
to listen to shortwave radio broadcasting?
Most countries in the world have
shortwave radio broadcasting. However,
the shortwave radio station in a certain
small country can only cover the territory
of such country, owning to small
transmitting power, which cannot be
received well by our country. Even a
station with strong power, the receiving
effect depends on geographical location
within or beyond coverage range. For
example: some frequencies of China's
Central People's Broadcasting Station
shortwave radio broadcasting can be
received well in our northeastern region,
but badly in China's southwest region.
Thanks to the national cultural and
political background of different
countries, the shortwave radio content
varies with country. In general, the
international shortwave radio program
contains world news, national news and
local news, news reviews, national
culture, music appreciation, language
teaching, etc. Some countries even set
up police information announcement,
weather forecast, marine information
forecast and other program. It must be
stressed that the official radio station of
each national government represents its
political positions and economic
interests. Therefore, when listening to
international broadcasting, you should
have ability to make judgment.
This depends on your listening environment. The reinforced
structures will shield the broadcast signal. In some remote areas,
mountains and mining areas, the shortwave signal will be slightly
weak, so it is necessary to install the outdoor antenna.
⑧
Is the shortwave signal clear?
The effect of listening to shortwave broadcasting depends on the
strength of radio transmitting power, the performance of radio and
the receiving location and other environmental factors. With the
improvement of radio technology, the listening effect will get
better and better.

○

⑩
How to test the effect of an
external antenna?
Must the external antenna be very high and long?
In a general listening environment,
turn the radio to a relatively weak
shortwave radio station, and go outside
of the room while listening. If the
shortwave radio signal is enhanced,
outdoor antenna should be installed to
improve the receiving effect. However,
if there is a strong TV station, FM
radio, BP machine and other radio
communication antenna near the
receiving location, the strong
interference signal will cause poor
receiving effect of shortwave external
antenna.
In short, shortwave external antenna will get better effect if it is high and long. But, higher and longer antenna doesn’t
imply better effect. Sometimes, sensitive antenna will introduce strong radio interference wave. Therefore, the height
and length of the external antenna should be adjusted according to the actual needs.

FM broadcasting
FM (FM) is a close-range high-fidelity radio system, which is the broadcast system with most rapid development, the
largest number, and best sound quality.
In some developed countries, a city even has 30 FM radio stations. Since the 1980s, China has built a large number of
FM radio stations, and almost all of them can play stereo programs. China FM radio frequency: 87 ~ 108 MHz, the
frequency interval 0.1 MHz, radio frequency from several hundred watts to twenty kilowatts.
Special warning: do
not install outdoor
antenna in the
multi-lightning area!
○
12
What signal will affect FM reception?
Powerful VHF TV radio broadcasting and personal
computer switching power supply radio wave will
interfere with the FM reception. In addition, the
FM radio stations with adjacent frequency and
strong transmitting power will interfere with each
other, leading to poor reception effect.
○
13
How far is the receiving distance of
the FM radio?
FM radio frequency is very high, and the radio is
transmitted in a linear way. The higher the
transmitting antenna, the greater the power, the
larger the coverage, and the farther the transmission
distance. FM radio transmission distance is usually
30 to 100 km.
