If your Tecsun Receiver is experiencing issues with storing stations or storing them with noise using ATS (Automatic Tuning System), it could be due to weak station frequencies or interference in your area. Try manually searching for the station. Alternatively, lower the antenna or relocate to another area and try again.
Why does my Tecsun Receiver keep turning off by itself?
If your Tecsun Receiver turns off unexpectedly while you're listening, it could be due to two reasons. First, the batteries might be low, so try replacing them. Second, the sleep timer may be activated; in that case, simply turn the radio on again.
How to fix a Tecsun Receiver that will not turn on?

Why is AM reception so poor in the USA on my Tecsun PL-390 Receiver?
If you're experiencing poor AM reception in the USA with your Tecsun Receiver, it might be due to the 10kHz step used in the USA for AM frequencies. To resolve this, turn off the radio and press the [9/10kHz] button to select 10kHz.
Why does my Tecsun Receiver alarm only play noise?
If your Tecsun Receiver's alarm produces only noise when activated (alarm by radio), it could be due to several reasons. First, ensure that you have properly preset your alarm station. Also, verify that the radio station is broadcasting in your location at the set time. If you are in another city where your preset frequency isn't available, consider setting the alarm to use the buzzer instead.
Why can my Tecsun PL-390 Receiver only receive limited FM stations in Japan?
If you can only receive a limited number of FM stations on your Tecsun Receiver in Japan, it's likely because the FM frequency range is set to 76~90MHz, which is standard for Japan. To resolve this, turn off the radio, press and hold the [FM SET] button, then press the [FM SET] button again to select the 76~108MHz range.

The Tecsun PL-390 is a versatile DSP receiver designed for a wide range of radio listening, including FM stereo, Shortwave (SW), Mediumwave (MW), and Longwave (LW) bands. It incorporates advanced DSP si4734 microchips from Silicon Labs, USA, which digitize analog AM/FM broadcasting signals using modern software technology and radio principles. This technology significantly enhances the radio's sensitivity, selectivity, signal-to-noise (S/N) ratio, and anti-interference capabilities, providing a superior listening experience.
The PL-390 offers a comprehensive set of functions for tuning, storing, and managing radio stations, as well as several utility features like alarm, sleep timer, and intelligent lighting.
The radio provides multiple ways to tune into stations:
The PL-390 has a total of 550 preset memories: 100 for FM, 100 for MW, 100 for LW, and 250 for SW.
Press and hold [POWER] until "SLEEP" and "30" appear. Rotate the [TUNING] knob to set the sleep timer from 1 to 120 minutes, or select "On" for permanent operation. The radio will auto-turn off after the set time. The default is 30 minutes.
Press and hold [TIME] until the hour flashes. Rotate [TUNING] to adjust the hour. Press [TIME] again, and the minutes will flash. Rotate [TUNING] to adjust minutes. Press [TIME] again to confirm. If no confirmation within 3 seconds, it auto-confirms. Direct keypad entry is also possible (e.g., 0635 for 6:35).
The PL-390 supports two alarm types: buzzer and radio.
Press and hold [1] to activate key lock (▀ symbol appears). Press and hold [1] again to deactivate (▀ symbol disappears).
The backlight illuminates for 3 seconds when any key or knob is operated.
When listening to FM stereo, press [FM ST.] to activate stereo reception (4)) symbol appears). If the signal is weak, press [FM ST.] again to turn off stereo (4)) disappears) for better reception. Stereo function only works with stereo broadcasts.
Repeatedly press [AM BW] to select bandwidths of 6, 4, 3, 2, or 1 kHz.
These settings are adjusted when the radio is off.
