If executed correctly, the radio will bypass its normal boot sequence and enter the service menu. On some versions, you may need to set Setting 01 in the regular menu to 36 before attempting this sequence.
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 anytone at5555n ii service menu work
: Controls the depth of the audio injected into the AM carrier. Setting this too high causes "clipping" and splatter, which distorts your signal and bleeds onto neighboring channels. If executed correctly, the radio will bypass its
: Controls the Local Oscillator (LO) offset. This should be adjusted first if you are off-frequency in USB or LSB modes. fr0, fr4, fr5, fr9 Adjusting these values changes the voltage or current
He powered the radio off, counted to ten, and powered it back on.
What are you trying to fix? (e.g., off-frequency, low power, inaccurate S-meter) Do you have a frequency counter or dummy load available?
