Grundig 400 PE - Manual (Page 11)

MANUAL TUNING: Use the regular TUNING buttons to go
up or down frequency. Be aware that when using manual tuning, it
is possible to tune right out of the shortwave band you have
entered. You are in the band as long as the band’s number, e.g.
25m, is in the display.
