19.8 Common Functions for Scan
Dropout Delay Time
Dropout Delay Time is the time from when the transceiver finishes receiving signals until the transceiver resumes
scanning.
The transceiver pauses scanning when the transceiver receives a call during the scan. The transceiver resumes scanning
after the transceiver finishes receiving and then the time configured for Dropout Delay Time elapses.
The following are conditions to resume scanning:
• There is no signal to receive.
• The QT tone, DQT code, or RAN code matching state is reset.
• The Group ID matching state is reset (LTR Trunking System).
The transceiver activates Talkback depending on the configuration for Revert CH/GID while the length of time configured
for Dropout Delay Time is counting down.
If the transceiver pauses scanning while the amount time configured for Dropout Delay Time is counting down, the
transceiver monitors Priority Channel 1 or Priority Channel 2 by using Lookback if the paused channel is not Priority
Channel 1 or Priority Channel 2.
Configuration using KPG-111D/ DN

Dwell Time
The scan pauses when the PTT switch is pressed to transmit during the scan. Dwell Time is the time from when the
transceiver completes transmitting until the transceiver resumes scanning.
The transceiver activates Talkback depending on the configuration for Revert CH/GID while the amount of time configured
for Dwell Time is counting down.
If the transceiver pauses scanning while the amount time configured for Dwell Time is counting down, the transceiver
monitors Priority Channel 1 or Priority Channel 2 by using Lookback if the paused channel is not Priority Channel 1 or
Priority Channel 2.
Configuration using KPG-111D/ DN
Configuring the Dwell Time (
Lookback
Lookback is used to check a Priority Channel at a constant interval while the transceiver is receiving on a normal channel
(Channels other than Priority Channel) and also a Priority Channel is configured for the transceiver.
The transceiver selects the interval time to check the Priority Channel (Lookback Time A or Lookback Time B) based on
the receiving status of the Priority Channel.
Lookback Time A
Lookback Time A is the interval time to check for a signal on a Priority Channel while the transceiver is receiving a signal
on a normal channel which is different from the Priority Channel.
The Lookback Time A must be shorter than Lookback Time B since the transceiver may receive a call on the Priority Scan.
