Anytone At-5555n Ii Service Menu Here

Repeated test transmissions during alignment generate rapid heat. Ensure the radio's rear heatsink remains cool to the touch.

Never perform service menu adjustments while connected to a live antenna. You will cause local spectrum interference and varying SWR readings will skew your power calibrations.

Sets the voltage trigger points for the Automatic Squelch (ASQ) and manual squelch circuitry. If your ASQ is cutting off the ends of transmissions or failing to open for weak signals, these parameters tune the hysteresis loop. 5. FM Deviation and Modulation Gain

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

Use this to set the main frequency baseline. Adjust this first if the radio is significantly off.

While exact parameters can shift across manufacturing batches, the core alignment groups include: 1. Frequency Calibration (REF / FREQ)

Before changing a single value, scroll through every menu item and write down the exact factory-assigned number for your specific serial number.

: Used for fine-tuning specific frequency points (e.g., .00, .04, .05, .09 offsets) by adjusting varicap voltage. Google Groups Factory Reset & Band Expansion Full Reset : If needed, turn the radio on while holding until "RES" then "REND" appears. Frequency Expansion
