The Anytone AT5555N II service menu offers a wealth of options for customization, troubleshooting, and upgrades. By understanding how to access and navigate this menu, you'll be able to unlock the full potential of your two-way radio. Always exercise caution when making changes, and consult the user manual or manufacturer's support if you're unsure.
If local operators report that your audio is too quiet or heavily distorted, the service menu allows you to adjust the internal microphone amplification stages. Increasing the AM modulation depth or FM deviation too high will cause "splatter" across adjacent channels, while setting it too low makes your signal unreadable. 3. S-Meter Calibration
The microprocessor inside the AT-5555N II uses digital-to-analog converters (DACs) to regulate hardware functions. Adjusting these values changes the voltage or current delivered to internal circuits, altering how the radio performs. Key Adjustable Parameters
Sets the modulation depth for AM, ensuring clear, high-percentage modulation. 3. Receiver and Transmitter Calibration
Adjusted to ensure the radio outputs the factory-specified wattage (typically 12W AM carrier, 30W FM) into the dummy load.
: Requires an RF spectrum analyzer or a highly sensitive scope to minimize the carrier spike while keying the mic without speaking. 3. Mode Power Adjustments (AM-P / FM-P / SSB-P)
To "unlock" the inner workings of the radio, follow these steps: : Ensure the radio is completely off.
