The display will show REST or flash all elements, resetting parameters back to default configurations (typically defaulting the baseline band layout to a 25.615 to 28.305 MHz spectrum).
| Item | Description | Notes | | :--- | :--- | :--- | | | S-Meter Calibration | Adjusts the signal strength bar display. S1 is usually the "hang" threshold; S9 is the high signal threshold. Requires a calibrated signal generator for accuracy. | | PO (Power Output) | RF Power Adjustment | Sets the maximum power output for High, Mid, and Low settings. Usually, you select the power level on the front panel first, then adjust the value in the service menu. | | MAX FREQ | Frequency Expansion | Sets the upper and lower frequency limits. Often used to "unlock" the radio for extended Tx/Rx ranges (e.g., 24.000 MHz – 32.000 MHz). | | SQL (Squelch) | Squelch Threshold | Sets the point where the audio mutes in the absence of a signal. | | MIC | Microphone Gain | Adjusts the modulation depth. Too high causes distortion; too low makes you sound quiet. | | BFO | Beat Frequency Oscillator | Adjusts the frequency offset for USB/LSB modes. Critical for clear SSB voice quality. | | TCXO / FREQ CAL | Frequency Calibration | Used to correct frequency drift. If your voice sounds "off-frequency" to others, this corrects the reference oscillator. | | AM CAL | AM Modulation | Sets the modulation percentage for AM mode. |
Do not attempt to adjust transmission settings without a dummy load, a calibrated wattmeter, and an accurate frequency counter connected to your radio. How to Access the AnyTone AT-5555N II Service Menu anytone at-5555n ii service menu
Accessing it voids the warranty if misused—but for experienced operators, it’s a precision instrument.

Press and hold down both the FUNC button and the PUSH (Channel selector) knob simultaneously. Requires a calibrated signal generator for accuracy
Controls the maximum frequency deviation for FM transmission (typically set for 2.5 kHz or 5.0 kHz depending on channel spacing rules). 4. S-Meter Calibration (RX S1 / RX S9)
Note that significant adjustments to the bf matrix will require you to cycle through and realign the fr0 through fr9 parameters to ensure cross-mode symmetry. 2. Fine-Tuning Modulation and RF Power Output
