• Elakkan mendedahkan unit kepada cahaya matahari langsung, suhu melampau atau kelembapan yang tinggi.
• Keep the transceiver away from dust and moisture.

Menyelesaikan masalah

This section addresses common issues you might encounter with your ICOM IC-7300 and provides basic troubleshooting steps.

1. Tiada Kuasa

• Periksa semua sambungan kabel kuasa.
• Sahkan bekalan kuasa berfungsi dengan betul dan memberikan volum yang betultage.
• Check the transceiver's fuse.

2. No Audio Output

• Ensure the AF gain (volume) knob is turned up.
• Periksa sambungan fon kepala atau pembesar suara luaran.
• Verify that the squelch level is not set too high.

3. Poor Transmission/Reception

• Inspect antenna connections and cable integrity.
• Ensure the antenna is properly tuned for the operating frequency.
• Check the SWR (Standing Wave Ratio) using the built-in meter. High SWR can indicate an antenna issue.
• Verify correct mode selection for the desired communication.

For more complex issues, consult the detailed troubleshooting section within the comprehensive manual or contact ICOM support.
