If you recently bought a used Icom IC-756 Pro, are troubleshooting strange behavior, or simply want to wipe old settings from the radio, performing a factory reset is one of the fastest ways to return the transceiver to a clean default state.
In this guide, I’ll walk through exactly how to factory reset the Icom 756 Pro based on the video demonstration. This process clears stored settings, including the previous owner’s callsign and customized configurations, and restores the radio back to factory defaults.
For ham radio operators who buy used equipment, this is an important maintenance step before putting the radio into regular operation.
What This Video Covers
This short walkthrough demonstrates:
- How to perform a CPU reset on the Icom 756 Pro
- Which buttons must be held during startup
- What gets erased during the reset
- What to expect once the reset is complete
The process is extremely quick and requires no tools or external software.
How to Factory Reset an Icom 756 Pro in Seconds
If you’re building or restoring a ham shack, you may also want to explore the broader resources in the Ham Radio Hub for additional setup and operating guides.
Why You Might Need to Factory Reset the Icom 756 Pro
There are several reasons why a CPU reset may be necessary on the Icom 756 Pro:
- Removing a previous owner’s settings
- Clearing stored callsigns
- Fixing corrupted menu settings
- Troubleshooting unusual operating behavior
- Returning the radio to a known baseline
- Preparing the radio for resale
A reset can also help after experimenting with advanced menu options or digital configurations that may have altered normal operation.
Because many used HF radios pass through multiple owners over the years, factory resetting is often the first thing I do after bringing one home.
How to Perform the Icom 756 Pro Factory Reset
The reset procedure shown in the video is simple and only takes a few seconds.
Step 1: Turn the Radio Off
Before beginning, power down the radio completely.
This ensures the reset sequence initializes correctly during startup.
Step 2: Hold the Required Buttons
While powering the radio back on, hold:
- INPUT
- FUNCTION
- INPUT
The button combination must be held during startup to trigger the CPU reset mode.

This initiates the internal reset process that restores factory defaults.
Step 3: Wait for the Reset to Complete
Once the radio powers up, the stored settings are cleared.
According to the demonstration:
- Callsign information is erased
- Previous custom settings are removed
- Factory defaults are restored
The process is nearly instantaneous.
After rebooting, the radio is effectively returned to a clean operating state.
What Gets Reset?
A factory reset restores the transceiver to its default configuration.
Settings Typically Cleared
Setting Type | Reset? |
|---|---|
Stored callsign | Yes |
User menu settings | Yes |
Customized operating parameters | Yes |
Factory defaults restored | Yes |
Because of this, you may need to:
- Reconfigure DSP preferences
- Restore CW settings
- Re-enter memory channels
- Reconfigure digital mode interfaces
- Adjust display preferences
If you rely heavily on custom configurations, it’s a good idea to document them before performing the reset.
Real-World Use Case
In the video, the reset was performed before handing the radio off to another operator.
That’s actually one of the most practical uses for a factory reset.
When selling or gifting a used transceiver, resetting it:
- Removes personal operating data
- Clears stored callsigns
- Gives the next owner a clean starting point
- Prevents configuration conflicts
Using a Factory Reset Before Selling a Radio
I’ve found this especially useful with older HF rigs where previous owners may have heavily customized settings over time.
For operators buying secondhand equipment, a reset can eliminate many mysterious operational quirks immediately.

Pros and Cons of Performing a Factory Reset
Pros
- Fast and easy procedure
- Clears unwanted settings
- Helps troubleshoot software-related issues
- Restores predictable baseline operation
- Useful when buying used radios
Cons
- Erases all personalized settings
- Requires reconfiguration afterward
- Memory channels may need to be rebuilt
- Some operators may forget important custom settings
Overall, the benefits usually outweigh the drawbacks when troubleshooting or transferring ownership.
Who This Is For
This reset procedure is especially useful for:
- New owners of used Icom radios
- Ham radio hobbyists troubleshooting issues
- Operators preparing equipment for resale
- Anyone wanting to restore factory defaults
It’s particularly valuable for beginner-to-intermediate operators who may inherit radios with unknown settings already programmed into them.
Those building an HF station may also benefit from browsing the Antennas Hub for antenna setup guides and station optimization ideas.
Important Notes Before Resetting
Before performing a factory reset, keep these considerations in mind:
Save Important Settings
If your radio contains:
- Custom memories
- CW macros
- DSP preferences
- Specialized filter settings
you may want to document them first.
Ensure Stable Power
Avoid interrupting power during the reset process.
Although the procedure is simple, stable power is always recommended during any firmware or memory-related operation.
Understand That Everything Returns to Default
After resetting, the radio behaves like it just left the factory.
That means you’ll likely need to spend some time reconfiguring the transceiver for your operating style.
Final Verdict
The Icom 756 Pro factory reset procedure is quick, straightforward, and extremely useful for restoring a clean operating environment.
Whether you’re troubleshooting odd behavior, removing old callsign information, or preparing the radio for a new owner, the reset process only takes a few seconds and can solve a surprising number of issues.
For used HF radios in particular, performing a factory reset is often one of the smartest first steps you can take.
