Icom Ui-7 Am Fm Unit -

If you acquire a UI-7 and it isn’t working, try these fixes:

| Symptom | Likely Fix | | :--- | :--- | | No response from the radio | Check the 3.5mm plug is fully seated in the REMOTE jack, not the MIC jack. Clean the plug with contact cleaner. | | Volume changes erratically | The encoder is dirty. Spray DeoxIT D5 into the gap around the knob shaft and rotate vigorously. | | PTT transmits but no audio control | The internal logic chip is confused. Unplug the UI-7, turn off the radio, wait 30 seconds, then reconnect and power on. | | F-Key does nothing | The F-Key is not assigned. Go into the IC-706 menu and assign a function (see section above). |

The UI-7 is not a standalone device. It requires a compatible Icom main transceiver. The primary pairings are: icom ui-7 am fm unit

Note: The UI-7 typically connects to the main transceiver via a standard 8-pin modular connector, but for full AM/FM audio and advanced control, specific wiring and bus connections are required.

The Icom UI-7 is not a standalone radio. It is an optional internal unit designed specifically for the Icom IC-705 (and potentially its predecessors like the IC-706 series, though primarily for IC-705). Its sole purpose is to add broadcast band AM and FM reception (typically 0.5–1.7 MHz AM and 76–108 MHz FM) to the IC-705, which otherwise is an HF/50/144/430 MHz all-mode transceiver but does not include wide-band broadcast FM as a standard feature.

Important: Some confusion exists because Icom’s naming convention overlaps. The UI-7 is not a standalone receiver or a car stereo. For the IC-705, it’s an internal module that plugs onto the main board.

Installing the Icom UI-7 AM/FM Unit requires careful planning. Unlike a consumer-grade CB radio microphone, this is a network device. The UI-7 is not a standalone device

For large yachts with two helms, you can install two UI-7 units. Both units share the same main transceiver. This eliminates the need to buy two complete VHF radios. One person can talk on VHF from the lower helm while another listens to AM/FM at the flybridge.

The IPX7 (or IPX8 depending on configuration) waterproof rating means the UI-7 is designed for exposed helm stations. Ideal locations include:
