Troubleshooting

Symptom	Possible Cause	Corrective Action
No power	Dead batteries, incorrect adapter	Replace batteries; use only specified 4.5V AC adapter.
Poor FM reception	Antenna not extended, location	Extend telescopic antenna fully; move near window.
No shortwave signals	Time of day, antenna	Shortwave propagation better at night; use external antenna.
Memory lost	Backup capacitor depleted	Leave batteries in for 24+ hours to recharge capacitor.
Distorted sound	Strong local signal, headphone	Reduce volume; disconnect headphones if using speaker.
SSB signals unclear	Fine tuning not adjusted	In SSB mode, use FINE TUNE to clarify voice.

Reset: Remove batteries and AC adapter for 5 minutes to reset microprocessor.
