When you unplug your sauna, you might find that the radio display says ‘MW’ instead of ‘AM’. This means it reset to European tuning.
To return to your AM stations, turn the radio on, hold down the ‘BAND’ button, and release the button when you hear a ‘beep’ and the display shows ‘EUROPE ‘. Press the button one time so the display reads ‘USA1’, then let the button go. Then press and hold down the button one more time until it beeps again.
Tuning for the standard AM broadcast band is now restored.
