Lookback
Lookback is the function to periodically checks for a Priority Channel if a Priority Channel is configured for the transceiver
and the transceiver receives on a normal channel (a channel which is not Primary Channel).
Either Lookback Time A or Lookback Time B is applied for the interval to initiate checking for a signal on a Priority Channel
according to the receiving status of the Priority Channel.
Lookback Time A
Lookback Time A is the interval time to check during a Priority Scan for a signal on a Priority Channel without a carrier
while the transceiver receives a signal on a normal channel whose carrier is different from the carrier of the Priority Channel.
Since the transceiver may receive a call on the Priority Channel, the time configured in Lookback Time A must be shorter
than the time configured in Lookback Time B.
Lookback Time B
Lookback Time B is the interval time to check during a Priority Scan for a signal on a Priority Channel which does not match
the QT/DQT in an Analog Conventional system or a Priority Channel which does not match the Color Code in a DMR
Conventional system even though a carrier exists, while the transceiver receives a signal on a normal channel whose carrier
is different from the carrier of the Priority Channel.
Note
If DMR digital signals are received on a normal channel in a DMR Conventional system, Lookback Time A and Lookback
Time B function according to the sum of 500 ms added to the value configured using KPG-D1/ D1N.
