3 DMR function
Behaviors When an Asynchronous State Occurs (Active Site Hunt)
Type
Description
Operating the transceiver
Note
Configuration using FPU
'■ Standard model
■ Basic model
If the transceiver cannot detect a synchronization signal from the repeater, the transceiver sends a Wakeup
message to the repeater to prompt synchronization when the transmission is on the Revert Channel or a
selected channel.
The wait time until a synchronization signal is sent and the number of times for the transceiver to send the
Wakeup message are determined by the configurations of Sync Wakeup Wait Time and Number of Wakeup
Message Retries.
A Wakeup message is sent as follows according to the configuration of Active Site Hunt.
Configuration
Enabled
The transceiver searches for the repeater available for synchronization, and if there is a
synchronized channel that is equal to or higher than the RSSI level set by Standard Site
Roaming Level, the search for the repeater terminates at the time.
The synchronized channel becomes the Revert Channel.
Disabled
If the transceiver cannot detect a synchronization signal from the repeater, the transceiver
sends a Wakeup message to the repeater to prompt synchronization when the
transmission is on the Revert Channel or a selected channel.
If a response from a repeater cannot be detected after a Wakeup message is sent for the
number of times configured in Number of Wakeup Message Retries, a Call Fail Tone (2
beeps) sounds from the speaker of the transceiver, and "OUT OF R" appears on the
display for 1 sec.
Wakeup Message sending
The following setting items are FPU setting items.
To use this function, "Site Roaming (DMR)" must be configured for Zone Type by using KPG-D6/ D6N.
The judgment of the RSSI level depends on setting of "Standard Site Roaming" when moving to Revert
Channel in the Active Site Hunt function operation. The setting of "Quick Site Roaming" is ignored. When
"Standard Site Roaming" is Off, the adjusted threshold level is used to determine the RSSI level.

Active Site Hunt
Description
During transmission while the synchronization signals cannot
be detected.
Transceiver behavior :
Send the wakeup message to the repeater from Revert
Channel.
If there is a response from the repeater and synchronization
is established, transmission becomes possible.
