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.

1.Make sure the system's P25 Level option is set to Auto (see “Adjusting the P25 Level (Motorola and Conventional Systems Only)” on Page 79).

2.Hold on an active digital channel on the system.

3.While holding down , briefly press the scroll control twice. The next to last line on the display now shows the digital error rate and the AUTO decode threshold start level (0-20). The last line on the display shows the decode threshold levels for the system.

4.Allow the scanner to monitor channel activity for several minutes. The error rate should drop for each transmission and the threshold levels should automatically adjust to a more optimal setting. Then, once the threshold level settles to a stable setting, make a note of the values. This is the system's optimum decode threshold.

5.While holding down , rotate the scroll control to set the AUTO decode threshold start level to a setting that most closely matches the system's optimum decode threshold. Now, when the scanner stops on a system, it will use this threshold as the starting point for automatic optimization.

6.While holding down , briefly press the scroll control to exit this mode.
