Fast & precise
Move rooms and symbols with mouse or set their sizes and distances numerically when high precision is required.
Multi-platform
Use your mobile device on location and complete the work on your computer at the office.
3D mode
See your project in 3D, as many floors as you need. Camera can be freely positioned.
Create detailed and precise floor plans. See them in 3D or print to scale. Add furniture to design interior of your home. Have your floor plan with you while shopping to check if there is enough room for a new furniture.
Proceed at your own risk. Entering the service menu and changing values incorrectly can:
Recommendation: Write down the original value of every setting you change. Do not adjust anything unless you own a calibrated frequency counter, a watt meter with a dummy load, and an oscilloscope (for modulation).
Once inside, the navigation logic changes from standard operation: anytone at-5555n ii service menu
Most stable method:
Do not simply switch off the main DC supply while inside the menu; allow the microcontroller to close its write-protect routines. Proceed at your own risk
Note: Your stock values may vary. Write them down before changing anything!
| Menu Item | Function | Typical Adjustment | |-----------|----------|---------------------| | S-01 | PLL Reference Frequency (Coarse) | Adjust for frequency counter accuracy | | S-04 | AM Power (Low) | Sets carrier level on AM mode | | S-05 | AM Power (High) | Sets peak AM power | | S-07 | SSB Power (Low) | ALC threshold for low SSB | | S-08 | SSB Power (High) | ALC threshold for high SSB | | S-11 | FM Deviation | Sets FM modulation width | | S-20 | S-Meter Zero (No signal) | Adjust until meter reads S0 with antenna disconnected | | S-21 | S-Meter Calibration (S9) | Inject S9 signal (50µV) and adjust | Recommendation: Write down the original value of every
Once the Service Menu is active, the standard operational buttons are remapped to navigation functions:
If your AT-5555N II is heard "off frequency" on SSB (e.g., you sound low pitch or high pitch to other stations):
Once in the service menu, navigation is generally straightforward:
