Set the P25 Threshold mode to Manual in Site Options or System Options for a
Conventional channel.
Press
Func then Dept to hold on a Site or Channel to hold on a digital Channel.
The first line on the display now shows the digital error rate and the decode threshold setting
(5-13). The second line on the display shows the decode threshold levels for the site.
Allow the scanner to monitor the site or channel 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
value. This is the site’s or channel’s optimum decode threshold.
Press
Func and rotate the Scroll Control to set the MAN decode threshold start level to a
setting that most closely matches the system’s optimum decode threshold. Whatever you set
at this point will be remembered for this site as the starting point for the auto-tuning function
for subsequent transmission on site. See also P25 Threshold Level, page 64.
