Cannot change frequencies on the radio
Last Updated: 12/03/2013
The Powerwerx DB-750X radio has a mode that locks operations to the current band. This affects the radio when operating in VFO mode.

If you find that you cannot enter a frequency outside the current band while in VFO, access Band in the set menu and set it to Off.

Once off, full functionality of the radio is restored
