Changing settings in the service menu directly impacts the radio's hardware.

Before proceeding, it is vital to understand that the service menu is designed for factory calibration and certified radio technicians.

The "expansion" to the 11-meter (CB) band is typically handled via a button combination (hold FUNC + EMG while powering on) rather than physical wire cutting on newer boards [5, 12].

In addition to the physical front-panel service menu, many operators prefer to use a PC and the official AnyTone programming software Software For Anytone AT-5555N II and quick run. . This approach is generally safer and vastly easier for users than pushing button combinations. anytone at5555n ii service menu updated

To get the most out of your AnyTone AT-5555N II service menu without causing damage, adhere to the following bench-testing protocols:

Before changing anything, write down the factory defaults. There is no "Reset to Factory" for the service menu specifically.

Note: These addresses are for the model only, not the original 5555N.

Sets the maximum frequency swing for FM audio. This must be aligned strictly to standard limits (typically 2.5 kHz for narrow or 5.0 kHz for wide) to keep from bleeding into adjacent channels. 6. S-Meter Calibration (S-MTR) Menu Label: RX-S or S9-CAL Adjust values incrementally; key the mic briefly to

: Lower values on AM modulation settings typically result in higher modulation (less clamping).

In the service menu, adjust the AM modulation settings ( AM Hi Pwr , AM Mod ) to increase the "swing" without distorting the audio, ensuring the radio peaks appropriately on PEP meters.

Used to resolve "S5-S7 noise" issues. Increasing this value (e.g., from 86 to 105) can quiet a noisy receiver.

What (like a dummy load or power meter) do you have available? Before proceeding, it is vital to understand that

In the standard user menu (long-press MENU ), navigate to menu item 01 and set it to 36 . This unlocks several hidden software parameters Anytone at-5555n II (version 2) | Page 39 - WorldwideDX Radio Forum .

Press the PUSH encoder knob to select a parameter, then rotate the knob to increase or decrease the specific numerical value.

Adjusting service menu parameters without a signal generator and frequency counter can permanently degrade radio performance. Always record your original factory values before making changes [13].
