This is from the manual - to turn LW on/off:
- Turn off the radio.
- Press and hold the [MW/LW] button until "ON" or "OFF" appears in the display: if " OFF" appears in the display, this means LW is turned off.
So, I guess do this until it toggles to "ON"?
Hope this helps - Kevin

Pressing the MW/LW selection switch as the manual suggests does indeed toggle the indicator between "on" and "off" for LW, however regardless, I cannot key in LW frequencies, nor can I tune them.
