system or site even if there is no traffic on any channel. (The scanner always
checks each channel in a system or site once even if the hold time is set to 0
seconds.) Select the number of seconds from 0 through 255 (2 is the default).
Set Delay Time
Set the number of seconds the scanner should wait after a transmission stops
before moving on to the next channel. Select 0, 1, 2 (default), 5, 10, or 30
seconds.
To have scanner leave the channel after a designated number of seconds whether
the transmission stops or not, select one of the negative values. Choose -10
seconds to have the scanner leave the channel after 10 seconds even if the
transmission is still going on; choose -5 seconds or -2 seconds to have the scanner
leave after 5 seconds or 2 seconds, respectively.
Set End Code
Choose whether the scanner recognizes any end transmission codes when deciding
to leave a channel. You have the following options:
Analog: The scanner recognizes only analog end transmission codes.
Analog-Digital: The scanner recognizes both analog and digital end codes.
Ignore: The scanner waits for the carrier signal to drop before it leaves a
channel.
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
P25 Waiting Time
On channels that contain a mix of analog and digital signals (i.e., where the Audio
Mode is set to All), it is possible to have false decode problems caused by digital
noise at the beginning of transmissions. To prevent this, a user-configurable 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 on this channel will lose the first part of
the transmission, up to the wait time you set here.
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. The scanner only applies the wait time setting to
Conventional or Motorola (non P25) systems, and only when the channel's Audio
