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 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.
