MEMO
PL-310ET 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.

TUNE INTO 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 (LW) broadcasting,
please rotate the radio or change it's location to achieve
optimum reception. Now, you can turn into your favorite
stations with any of the below tuning methods:
METHOD 1:
ETM (EASY TUNING MODE)
ETM is a unique tuning method designed by Tecsun. It
skillfully combines the reception circuitry & control
procedure to pre-select the 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.
Please follow below steps to tune into your preferred
frequencies employing ETM:
1. Press the [ETM] button and “ETM”
will appear on screen to enter Easy
Tuning Mode.
2. Press & hold the [ETM] button until
flashing
the frequency start running to auto
scan and store stations into ETM

memory,
within the present band.

3. When the frequency stops
running, turn 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 the ETM memory.

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 [VM/VF] button to switch
into frequency mode, and then rotate the [TUNING] knob to
select your desired station.
FAST/SLOW tuning is shown in the chart below for each band.
