©2026 AOR, LTD. April 23, 2026

Feature Improvements
- Added a recording indicator to the TETRA trunking screen.
- Adjusted the Usage display switching on the TETRA trunking screen to improve readability.
- Improved VFO operation so that, when [F] is active, turning the dial or pressing [▼]/[▲] changes frequency in 10× step increments.
- As part of display stability improvements during search, the S-meter is no longer drawn while the clock is being rendered.
- Changed LCD startup behavior so the backlight remains DARK until the opening screen appears.

Bug Fixes
- Corrected an issue where F-AU settings were not reflected during memory channel recall and scan operation.
- Corrected memory channel save/edit behavior so that F-AU settings are now stored properly.
- Corrected the valid argument range for the CC command used for DMR Color Code.
- Corrected an issue where the NXDN RAN Code readout could incorrectly display the Whitening Code during signal reception.
- Corrected incorrect file size and timestamp display for certain files shown by the SD DIR command.
- Corrected a search issue where 154.450 MHz could fail to be detected under specific search bank settings.
- Corrected abnormal alarm and timer recording behavior when PROTECT was set to ON.
- Corrected an issue where CyberSearch PASS frequencies were not applied after returning to the beginning of a bank.
- Corrected an issue where DMR Color Code, P25 NAC Code, NXDN RAN Code, DCR User Code, and DCR Whitening Code were displayed regardless of the DIGI.DECODE setting. These values are now displayed only when DIGI.DECODE is ON.
- Corrected an issue where unexpected display artifacts could remain at the top of the screen during initial power-on.
