The AnyTone AT-5555N II is a high-performance 10-meter radio, but many of its most critical calibration settings—like power output and modulation—are tucked away in a hidden Service Menu. Because there is no factory "reset" for this specific menu, users must exercise extreme caution when making adjustments. How to Access the Hidden Service Menu

Accessing the service mode requires a specific sequence of button presses during the power-on cycle.

Preparation: Ensure the radio is connected to a dummy load or an antenna to prevent damage.

Initial Combo: With the radio OFF, press and hold both the [MENU] and [MODE] buttons. Power On: While holding those buttons, turn the radio on.

Secondary Sequence: Once the radio powers up, release the initial buttons and immediately press the following top-row buttons in order: [DW], [RB], [NB], [SCAN], [MEM], and [EMG].

Entry Confirmation: If successful, the display should show "FM" (representing the factory menu) or a numerical setting. Navigating and Saving Settings

Scrolling: Use the Channel Selector knob to cycle through different menu items (ranging from 1 to over 50).

Viewing Values: To see the current value of a setting, press the PTT (Push-To-Talk) button on the microphone.

Changing Values: To modify a value, hold the PTT while rotating the Channel Selector. Saving: Turn the radio off to save your changes.

CRITICAL WARNING: Always WRITE DOWN every original value before changing it. There is no software reset for these specific alignment values; if you change them without a backup, you cannot easily restore factory calibration. Key Service Menu Items and Fixes
