Opsætning
1. Tilslutning af strømforsyningen
Connect the supplied DC power cable to the transceiver's DC IN connector and to a stable 13.8V DC power source. Ensure correct polarity (red to positive, black to negative) to prevent damage.
2. Tilslutning af antenne
Connect a suitable HF/50MHz antenna to the ANT connector on the rear panel. For optimal performance and to protect the transceiver, use an antenna designed for the operating frequencies and ensure it is properly matched.
3. Tilslutning af mikrofonen
Plug the HM-219 hand microphone into the MIC connector on the front panel.
4. Første opstart
Tryk på MAGT button to turn on the transceiver. The ICOM logo will appear on the display, followed by the operating screen.

Betjeningsvejledning
Grundlæggende betjening
- Frekvensvalg: Brug den store MULTI dial to change the operating frequency. You can also directly input frequencies using the touchscreen keypad.
- Valg af tilstand: Tap the mode indicator on the touchscreen (e.g., USB, LSB) to cycle through available modes (SSB, CW, RTTY, AM, FM).
- Lydstyrkejustering: Brug AF/RF/SQL knappen til at justere lydudgangsniveauet.
- Fremsendelse: Tryk på SEND button or the PTT button on the microphone to transmit. Ensure your antenna is tuned before transmitting.
Brug af berøringsskærmen
The 4.3-inch color touchscreen provides intuitive access to various functions and settings.

Built-in Auto Tuner
The IC-7300 includes an internal automatic antenna tuner. To activate, press the AUTO TUNE button. The tuner will automatically adjust to achieve the lowest possible SWR for your connected antenna. This function is effective for SWR values up to approximately 3:1.
Opretholdelse
- Rensning: Brug en blød, tør klud til at rengøre transceiveren udvendigt. Brug ikke slibende rengøringsmidler eller opløsningsmidler.
- Ventilation: Ensure the ventilation holes on the top and sides of the unit are not obstructed to prevent overheating.
- Opbevaring: Når transceiveren ikke er i brug i længere perioder, skal den opbevares tørt og støvfrit.
Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Ingen strøm | Strømkabel frakoblet; forkert lydstyrketage; blown fuse. | Check power cable connections; verify 13.8V DC supply; inspect and replace fuse if necessary. |
| Ingen lydudgang | Volume too low; speaker/headphone disconnected; squelch set too high. | Adjust AF/RF/SQL knob; check speaker/headphone connection; reduce squelch level. |
| Kan ikke sende | Antenna not connected; high SWR; PTT button not pressed. | Connect antenna; use auto tuner or external tuner to reduce SWR; ensure PTT is engaged. |
| Dårlig modtagelse | Antenna issue; incorrect mode/frequency; high noise level. | Check antenna connection and type; verify operating mode and frequency; adjust noise reduction (NB, NR) settings. |
