Resolució de problemes
| Problema | Causa possible | Solució |
|---|---|---|
| Sense poder | Power cable disconnected; incorrect voltage; blown fuse. | Check power cable connections; verify 13.8V DC supply; inspect and replace fuse if necessary. |
| Sense sortida d'àudio | Volume too low; speaker/headphone disconnected; squelch set too high. | Adjust AF/RF/SQL knob; check speaker/headphone connection; reduce squelch level. |
| No es pot transmetre | Antenna not connected; high SWR; PTT button not pressed. | Connect antenna; use auto tuner or external tuner to reduce SWR; ensure PTT is engaged. |
| Mala recepció | Antenna issue; incorrect mode/frequency; high noise level. | Check antenna connection and type; verify operating mode and frequency; adjust noise reduction (NB, NR) settings. |
