16 SCAN
16.4 Common Functions for Scan
Lookback Time B
Lookback Time B is the interval time to check the Priority Channel in Priority Scan if the QT tone or DQT code, or RAN
code does not match that preconfigured for the transceiver though there is a carrier on the Priority Channel while the
transceiver is receiving on a normal channel having a different carrier from the Priority Channel.
In this case, it is supposed that another transceiver is using the channel; therefore, configuring longer time than the time
configured for Lookback Time A as the interval to check decreases the influence on the normal channel.
Configuration using KPG-169D/ KPG-170D/ KPG-175D

Starting Scanning by Linking with the Microphone (Off-hook Scan)
Supported Models: Mobile
Off-hook Scan is a function to start scanning regardless of the microphone hook status.
The transceiver scans as follows according to the configuration for Off-hook Scan:
Configuration
Enabled Pressing the Scan key causes the transceiver to start scanning regardless of the microphone On- or Off-hook state.
If the microphone is in the On-hook state, pressing the Scan key causes the transceiver to start scanning; however
if the microphone is in the Off-hook state, the transceiver cannot start scanning. If the microphone changes from the
Disabled
On-hook state to Off-hook state in Scan Mode, the scan pauses on the Revert Channel. When the microphone goes
to On-hook state, the transceiver resumes scanning.
Note
The microphone hook status can also be switched on by the AUX Input port to which "External Hook" is assigned. (Refer to
Available Functions for AUX Input Ports on page
Configuration using KPG-175D
Configuring the Off-hook Scan to be enabled or disabled (
Priority-channel Stop Tone
Priority-channel Stop Tone is the function to emit the Priority-channel tone from the transceiver when the transceiver
receives during the scan on the Priority Channel and then pauses scanning.
Configuration using KPG-169D/ KPG-170D/ KPG-175D
