10 ANALOG CONVENTIONAL SYSTEM
10.1 Initiating Voice Communications (Basic Transmission and Reception)
The transceiver considers a retransmission within this configured length of time as a continuous transmission. In the
following example, the counting of Time-out Timer continues because the transmission was started by a user pressing the
PTT switch while the TOT Reset Time was counting down.
Example 2: Time-out Timer: 30 s, TOT Reset Time: 10 s
Note
• If "Off" is configured for TOT Reset Time, the Time-out Timer will be reset immediately after the transceiver finishes transmitting.
• The timer will be reset if the zone or channel is changed while the TOT Reset Time is counting down.

Avoiding Interference with Other Communications (Busy Channel Lockout (Analog))
Busy Channel Lockout is the function to automatically restrict the transmission so as not to interfere with other
communications.
If an attempt is made to transmit on a channel that is already being used by other groups, the transceiver automatically
restricts the transmission.
If the PTT switch is pressed while Busy Channel Lockout is enabled, the transceiver cannot transmit with "BUSY"
appearing on the main display and a Warning Tone A sounding from the transceiver at the same time. The Warning Tone A
sounds from the transceiver until the PTT switch is released.
Following are conditions to disable transmission by Busy Channel Lockout (Analog).
Configuration
Busy Channel Lockout is disabled. Transmission is not restricted even if the channel on which the transceiver
No
attempts to transmit is busy.
Carrier Only The transceiver cannot transmit while the transceiver is receiving a carrier.
The transceiver cannot transmit if the transceiver receives a carrier and the received QT tone or DQT code does
Incorrect Tone not match the QT tone or DQT code preconfigured for the transceiver. However, the transceiver can transmit if
the received QT tone or DQT code matches the QT tone or DQT code preconfigured for the transceiver.
The transceiver cannot transmit until the received Optional Signaling matches the Optional Signaling
Optional Signaling
preconfigured for the transceiver.
The transceiver is controlled in the following manner according to the configuration for Transmit Mode on a channel where
"Mixed" is configured for Channel Type.
