Optimizing P25 Performance
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 '
option is
set to 'Auto'
.
2. Hold on an active digital channel on the system.
3. While holding down
Func
, 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.
