Anytone At5555n Ii Service Menu Updated ^hot^ [BEST]

For non-alignment settings like Mic Gain, SWR Protection, or Noise Reduction (NRC), use the standard background menu instead: Long-press for 2 seconds. Channel Switch to select a menu item. to enter the setting, adjust it, and press again to save. device.report

The method to enter the Service Menu is specific and varies slightly from other models. The key is a timed sequence involving button presses during startup. Here is the most reliable method, reported by users to be effective:

: Controls the local oscillator offset. Experts suggest adjusting lo first to get as close to the target frequency as possible before using bf for final tiny tweaks.

Press the PUSH button (or use the microphone Up/Down keys on certain firmware versions) to highlight the value field, then rotate the channel knob to increase or decrease the numerical setting.

Turn the radio off. When you turn it back on normally, the new calibration parameters will be active in the transceiver's non-volatile memory (EEPROM). Breakdown of Key Service Menu Parameters For non-alignment settings like Mic Gain, SWR Protection,

"My AM carrier is too high (10 watts), but the radio is set to low power." Solution: Go to P-07 (High Power Scale). Reduce the value from 120 to 85. This digitally reduces the drive voltage to the RD16HHF1 finals. Do not exceed 120.

The most common reason to use the service menu is to correct frequency drift or align the radio to a frequency counter.

Controls voltage across varicaps for precise frequency steps (.00, .04, .05, .09). Align these after any BFO change [6]. Local Oscillator Offset
