Anytone At-5555n Ii Service Menu [work]

Ensure your DC power supply is delivering a stable 13.8V. Do not let the radio overheat while testing continuous carrier modes like AM or FM.

While the curiosity to explore the full capabilities of the AT-5555N II is natural, maintaining the factory calibration is generally the best way to ensure the longevity and legal operation of the equipment.

The provides advanced radio operators and technicians with direct control over internal alignments, power outputs, frequency offsets, and modulation parameters directly from the front panel. It bypasses standard background programming software, allowing real-time calibration of Single Sideband (SSB), Amplitude Modulation (AM), and Frequency Modulation (FM) modes.

If you need help resolving a specific hardware issue with your radio, please let me know: Ensure your DC power supply is delivering a stable 13

Do not max out the power settings. Pushing the service menu values to the maximum limits will overheat the final amplifiers, distort your audio, and cause severe splatter across adjacent channels. To help provide more specific guidance, tell me:

To enter the hidden alignment menu on the AnyTone AT-5555N II, follow this specific button-press sequence: All LCD segments will illuminate for approximately 2 seconds

Never exceed the factory maximum power ratings, as this can destroy the final amplifier transistors (FETs). 4. Best Practices for Calibration
