Optimizing P25 Performance

You can optimize the scanner’s performance with digital APCO 25 systems. Follow these steps for each system where you can hear APCO 25 traffic.

Notes:

These steps work only when you can clearly receive the system. If you are in a weak-signal area or receive interference, these steps will not work. These steps do not compensate for weak signals or signals subject to interference.

If you set an incorrect decode threshold level in Step 5, the scanner might stop decoding all digital signals in the system. If this happens, change the setting to a value between 8 and 12 then repeat these steps.

*In Manual mode or Auto mode, if you rotate the knob clockwise, the threshold level is adjusted wider than default level. If you rotate the knob counterclockwise, the level is adjusted narrower.
