20.7.19 Transmit Busy Wait Time
Transmit Busy Wait Time is the maximum time for the
transceiver to withhold data transmission when the
channel is busy. The transmission is canceled when the
channel is busy even if the Transmit Busy Wait Time
elapses.
Transmit Busy Wait Time can be configured by using
KPG-101D.

Wait Time.)
20.7.20 Maximum ACK Wait Time
Maximum ACK Wait Time is the wait time for receiving
ACK after ending a data transmission. If the transceiver
does not receive an ACK within the Maximum ACK Wait
Time, the transceiver resends data.
Maximum ACK Wait Time can be configured by using
KPG-101D. Normally, the default setting is used.
Note:
Maximum ACK Wait Time can also be used for the transceiver
to automatically jump to the data channel with GTC and wait to
receive data.
A Long Data Message is sent several times. The receiving
party’s transceiver waits to receive the next data for the
Maximum ACK Wait Time. If the transceiver does not receive
the Long Data Message within the Maximum ACK Wait Time,
the transceiver stops waiting to receive the Long Data Message.

Wait Time.)
20.7.21 ACK Delay Time
ACK Delay Time is the time between when the
transceiver receives data and when the transceiver sends
an ACK.
This time must be shorter than Maximum ACK Wait Time
configured in the caller’s transceiver. In addition, this
period must be shorter than the Hang Time configured for
the repeater if ARQ is used in the LTR Trunked Radio
System.
ACK Delay Time can be configured by using
KPG-101D. Normally, the default setting is used.

20.7.22 Transmit Delay Time (Receive
Capture)
Transmit Delay Time is the duration that the transceiver
transmits unmodulated signals prior to data transmission.
With this function, a user can reliably receive data since
the transceiver at the receiving end stops scanning when
the transceiver at the transmitting end transmits
unmodulated signals. Therefore, a user can reliably
receive data even if the transceiver at the receiving end is
scanning or the Battery Saver function is enabled.
The Transmit Delay Time can be configured by using
KPG-101D. Normally, the default setting is used.

20.7.23 Data Transmit Modulation
Delay Time
The Data Transmit Modulation Delay Time is the duration
between when the transceiver starts transmitting and
when the transceiver starts modulating the MSK data.
This delay time is used to stabilize the transceiver before
starting the MSK modulation. For example, it may be
difficult to establish data communications when the
transmit and receive frequencies are widely separated or
the transceiver is used in extremely cold areas. In such
cases, configure this delay time longer in order to improve
data communications.
The Data Transmit Modulation Delay Time can be
configured by using KPG-101D. Normally, the default
setting is used.
