Functional Block Diagram

PL-390 is using DSP si4734 Microchips (from Silicon Labs in
USA) to digitalize the analog AM/FM broadcasting signal base
on the modern software technology and radio principles. It can
highly improve on radio's sensitivity, selectivity, S/N ratio and
anti-interference.

unit, install 3 x AA alkaline batteries observing the battery
polarity diagram on the back of the radio. Close the
battery door.

Installing batteries

2. Press the [POWER] button to turn on/off the radio.

TUNE IN STATIONS

Press the [POWER] button to turn on your radio, then
select your desired band by pressing the [FM], [MW/LW]、
SW[ ] or [ ] button. In case of receiving FM/ SW

broadcasting, fully extend the telescopic antenna for a
better reception. When receiving MW and LW broadcasting,
please rotate the radio or change it's location to achieve
optimum reception. You can rotate the [VOLUME] knob to
adjust to appropriate volume from 0 to 30 levels.
Now, you can turn into your favorite stations with any of the
below tuning methods:

METHOD 1: ETM (EASY TUNING MODE)

ETM is the unique tuning method designed by Tecsun. It
skillfully combines the reception circuitry & control
procedure to pre-select the suspected radio station and
temporarily auto stores them into the ETM memory (not the
regular 550 memories). This highly enhances the efficiency
when tuning into radio stations. Employing ETM to tune
preferred frequencies. you can easily tune into your desired
stations from those preferred frequencies.

1. Press the [ETM] button with
[ETM] shows on screen to enter
Easy Tuning Mode.

2. Press & hold the [ETM] button until
the frequency start running to
auto scan and store stations into
ETM memory, within the present
band.

3. When the frequency stop running,
turn around the [TUNING] knob to
select those stored stations.

Notes: While operating ETM to search for stations, a few
stations might be missed if there is interference in the
surrounding. In this case, you can simply key-in the
frequency, then press the [ETM] button to manually store it
into ETM memory.

PL-3 906

Tips:

FM station: When you are in a different city or country, you
should perform the ETM function again in stead of using
ATS function, because this will not delete any of the
stations already stored within the memory.

MW station: It is recommendable to perform the ETM
function during night time, because there are usually many
stations starting broadcasting at night.

SW station: It is recommendable to perform the ETM
function in the morning, afternoon as well as night time,
because the transmitting signal of SW is very unstable and
usually there are more stations that start broadcasting in
the late afternoon.

METHOD 2: MANUAL TUNING

Frequency searching: Press the [VF] button to switch into
frequency mode, and then rotate the [TUNING] knob to
select your desired station.

next available station.

METHOD 4: DIRECT KEYPAD ENTRY

To search for frequency, turn on the radio and press the
[VF] button to switch into frequency mode, press the
numeric keys [0] - [9] to enter the station frequency directly.

To search for memory, press the [VM] button to switch into
memory mode, then press the numeric keys [0] - [9] to
enter the preset memory number directly.

Notes:

1. Ignore the decimal point for FM band when inputting the
frequency numbers.
For example, FM 89.3 MHz, just enter 8 9 3.

2. If the entered frequency rate is not within the covering
area, the display would display “Err” (error) symbol.

WORKING WITH STATION MEMORIES

There are total 550 preset memories within the unit. 100
preset memories for each FM, MW, and LW band, and 250
for SW.

FM ATS:

1. Fully extend the telescopic
antenna and press the [FM]
button to select FM band.

2. Press & hold the [FM] button
with “PRESET ” flashing and the
frequency start running, then
you can scan and store your

MW/LW ATS:

Press the [MW/LW] button to select MW/LW band, then
follow step 2 of FM ATS.

SW ATS:

Fully extend the telescopic antenna and press the SW[ ]
or [ ] button to select SW band. There are two modes for
SW ATS tuning:

Mode A: Press & hold the [ ] button to ATS the stations
within all meter bands
Mode B: Press & hold the [ ] button to ATS the stations
within present meter band only.rotate the radio for better
location (MW & LW).

PL-3 90 9

Notes:

1. During ATS process in FM, MW / LW or SW (mode A),
pre-stored radio stations will be replaced automatically
by the new searched stations.

2. With ATS in SW (mode B), those existing memories will
not be replaced; all the newly found radio stations would
be stored in the blank memories addresses.

3. If there is too many interference in you surrounding or
many mirror/blank station being stored during ATS, you
should contract the telescopic antenna (FM & SW) or
rotate the radio for better location (MW & LW).

METHOD 2: MANUAL STORING STATON

1. Select band and tune to your desired station.

2. Press the [M] button with “preset” flashing

3. Press the [M] button again to store the station into
memory.
You can also wait for 3 seconds to auto store the station
into memory.

METHOD 3: SEMI-AUTO STORING STATION

While operating the “Auto Browse Station” function, you
can simply press on the [M] button to store the station into
memory to avoid storing unwanted stations and interfering
signals.

1. Press the [VF] button to switch into frequency mode.

2. Press & hold the [VF] button with “ “ advancing to
auto browse from one station to another.

3. While tuning to your favor station, press the [M] button
with “PRESET ” flashing to direct store the station into the

IMPORTANT MATTERS FOR USING BATTERIES

1. If no battery has been installed inside for long time, clock
of radio would stop to work. However, pre-stored
frequencies are still kept. Clock would work again after
new batteries being re-installed inside.

2. When the battery power is low, the " " symbol in the
display will flash to alert you for changing new batteries.
Besides it will turns off automatically when the power is
gone.

3. Mix using the used & new batteries would cause damage
of radio and also display the capacity of power incorrectly.

4. In case of radio not to be used for a long period, draw out
the batteries for preventing liquid leakage and damaging
the parts of radio.
