After updating, you will want to change the P25 Adjust Mode and Level.
To adjust the decode threshold, start with the scanner powered off. Then, follow these steps:
- While holding down the HOLD button, power on the scanner.
- Access the hidden P25 Adjust Mode menu by MENU –> Settings –> P25 Adjust Mode.
- Set the mode to 11, which is the optimal setting for most P25 systems.
- If you have previously adjusted the P25 Adjust Level, reset it to a value of 50 by MENU –> Settings –> P25 Adjust Level.
