For basic operation, the Icom Japan Support Portal or Icom America Support provide the Basic Manual, Advanced Manual, and CI-V command references freely. ⚠️ Important Precautions Before You Repair

Before you pick up a screwdriver or a soldering iron to service an IC-705, always remember these three rules:

Leveling the power across all bands (HF, 50MHz, 144MHz, and 430MHz) to guarantee clean 5W or 10W limits without overdriving.

If you are facing complex hardware failure, the best course of action is often to skip the DIY fix and send the transceiver to an authorized Icom service center to prevent permanent damage to the expensive SDR circuitry.
