transmission is still going on; choose -5 seconds or -2 seconds to have the scanner
leave after 5 seconds or 2 seconds, respectively.
Set Attenuator
Turn on attenuation to reduce the signal strength by 20 dB. When you turn on this
setting, all frequencies in Quick Search mode, Close Call mode, and the Band
Scope will be attenuated.
Set Audio AGC
Turn on Automatic Gain Control (AGC) for this system. When you activate this
feature, the scanner automatically adjusts the volume for each channel based on the
signal strength. You can turn on the gain control for Analog and Digital signals
separately.
To change the settings for the audio AGC, see Adjust Audio AGC
P25 Waiting Time
During search and Close Call operation, it is possible to have false decode
problems that result in digital noise at the beginning of transmissions. To prevent
this, a userconfigurable P25 wait time (from 0 to 1000 ms) has been added.
During the wait time, the scanner evaluates the received signal; if it detects P25
data, the scanner opens squelch immediately. If it does not detect any P25 data, the
scanner opens squelch as soon as the wait time expires.
Note: Any analog transmissions will lose the first part of the transmission, up
to the wait time you set here.
Select the number of milliseconds (after the start of a transmission) the scanner
should wait while checking for P25 data. Choose a number from 0 through 1000
ms in 100 ms increments. This setting will be applied in Close Call, Quick Search,
and Band Scope modes.
