■ Clear to transpond
The transceiver waits the transpond of DTMF if channel
is busy until channel open. This feature prevents the inter-
ference to other party.
6. Option Signalling (DTMF)
Built-in DTMF decoder is available for option signalling.
It is possible to use individual call, group call, Stun.
If the option signalling matches, a predetermined action
will occur.
If option signalling matches on a channel is set up with
option signalling, the channel LED will flash and option sig-
nalling will be released. The transpond or alert tone will
sound.
While option signalling matches (or if option signalling is
deactivated when you are transmitting), you can mute or
unmute QT/DQT/Carrier.
■ SP Unmute
You can select the type of SP Unmute system for each
channel. The selection is as follows.
Carrier, QT/DQT:
Channel with this option will not check ID Code in order
to open its speaker.
Carrier+DTMF, QT/DQT+DTMF:
Channel that is set with this option will have to check for
ID Code in order to open its speaker.
Default:
Carrier, QT/DQT.

Note:
When QT/DQT is not used, QT/DQT and QT/DQT+DTMF
can not be selected.
When DTMF is not used, Carrier+DTMF and QT/
DQT+DTMF can not be selected.
■ Auto Reset
If option signalling matches a group set up with option
signalling, option signalling is released. After matching op-
tion signalling, option signalling will temporarily reset auto-
matically.

■ 加强自动应答
如果信道直到打开均繁忙，车载台将等待DTMF应答。此特
性防止干扰到对方。
6. 可选信令 (DTMF)
内置DTMF解码器对可选信令有效。
使用单呼，组呼，遥毙。
如果可选信令相匹配，则触发预定的操作。
如果可选信令在使用可选信令设置的信道上相匹备，信道指
示灯将闪烁并且可选信令将被取消。应答或告警将发出声音。
当可选信令相匹配时（或如果当用户发射时可选信令被抑制
时），用户可以使QT/DQT载波静音或非静音。
■ 扬声器监听
可以为各信道选择如下扬声器监听系统类型。
载波，QT/DQT：
设定为该选项的信道打开其扬声器时将不检查 ID 代码。
载波+DTMF, QT/DQT+DTMF：
设定为该选项的信道打开其扬声器时必须检查 ID 代码。
初始值：
载波, QT/DQT。

■ 自动复位
如果可选信令与使用可选信令设置的组相匹配，可选信令被
取消。可选信令匹配之后，可选信令将临时自动复位。
