What to do if rotary tuning and front panel buttons do not respond on Radio Shack DX-398?
If your Radio Shack Radio's rotary tuning and front panel buttons aren't responding, it's possible the keypad is locked, which is indicated by a key symbol on the display. To unlock it, simply press the M button.
Why does my Radio Shack DX-398 Radio have weak or intermittent sound?
Weak or intermittent sound from your Radio Shack Radio can occur for several reasons: * The internal batteries might be weak. Check them and replace or recharge as needed. * The antenna may need adjustment. Try adjusting the telescoping antenna or connecting an external antenna. * The signal could be blocked by metal or concrete. If you're inside a vehicle or metal-frame building, move the receiver near a window.
What to do if scanning stops on a frequency that has an unclear transmission on Radio Shack DX-398?
If your Radio Shack Radio scanning stops on a frequency with an unclear transmission, it might be that the frequency is not tuned properly. Try to fine-tune the frequency. Alternatively, the frequency could be one of the receiver’s birdie frequencies, in which case you should tune to another frequency.
How to fix frequency not changing when turning rotary tuning on Radio Shack DX-398?
If the frequency on your Radio Shack Radio doesn't change when you turn the rotary tuning, check the FAST/SLOW/STOP setting. If it's set to STOP, change it to FAST or SLOW.
