VOX 与免提操作
VOX Operation32.1 VOX 功能概述VOX Overview
The VOX (Voice Operated Transmit) system may be used for hands-free activation of the transmitter, by the voice input to the microphone or Bluetooth headset.
When the VOX function is activated, the sound is automatically transmitted by voice from the connected microphone or Bluetooth headset.
VOX（声控发射）系统可通过输入到麦克风或蓝牙耳机的语音，实现发射的免提激活。
VOX 功能启用后，来自所连接麦克风或蓝牙耳机的声音会自动触发发射。
32.2 开启 VOX 并选择声源Setting the VOX Function
- Press and hold the [FUNC] knob.
- Select [OPERATION SETTING] → [TX GNRL].
- Rotate the [FUNC] knob to select [VOX SELECT].
- Rotate the [FUNC] knob, or touch "<" or ">" on either side of the value, to select "MIC" or "Bluetooth".
- Press the [FUNC] knob, or wait for about 3 seconds, to save the setting.
- Press the [BACK] key several times to return to normal operation.
- Press and hold the [FUNC] knob.
- Touch [VOX].
While the VOX function is activated, "VOX" will be displayed.
- 按住 [FUNC] 旋钮。
- 选择 [OPERATION SETTING] → [TX GNRL]。
- 旋转 [FUNC] 旋钮，选择 [VOX SELECT]。
- 旋转 [FUNC] 旋钮，或触摸数值两侧的 "<" / ">"，选择 "MIC" 或 "Bluetooth"。
- 按 [FUNC] 旋钮，或等待约 3 秒，保存设置。
- 多次按 [BACK] 键返回正常工作状态。
- 按住 [FUNC] 旋钮。
- 触摸 [VOX]。
VOX 功能启用期间，屏幕上会显示 "VOX"。
| 设置值Setting | 说明Description |
|---|---|
| MIC | 由所连接麦克风的语音自动触发发射 |
| Bluetooth | 由所连接蓝牙耳机的语音自动触发发射 |
32.3 关闭 VOXDisabling the VOX Function
To cancel VOX and return to PTT operation, repeat steps 7 and 8 above: press and hold the [FUNC] knob, then touch [VOX].
When the VOX function is OFF, pressing the "Call button" on the Bluetooth headset once will engage the FTX-1 in transmit, and then a call can be made using the Bluetooth headset. Press the "Call button" again to return the FTX-1 to receive.
要取消 VOX、回到 PTT 操作，重复上述第 7、8 步即可：按住 [FUNC] 旋钮，然后触摸 [VOX]。
VOX 功能关闭时，按一次蓝牙耳机上的"呼叫按钮"即可让 FTX-1 进入发射，随后可用蓝牙耳机通话；再次按该按钮，FTX-1 回到接收。（不同蓝牙耳机的按钮名称可能不同。）
32.4 设置 VOX 增益Setting the VOX Gain
The VOX Gain may be adjusted to prevent accidental transmitter activation in a noisy environment.
- Press and hold the [FUNC] knob.
- Touch [VOX GAIN].
- While speaking into the microphone or Bluetooth headset, rotate the [FUNC] knob, or touch "<" or ">" on either side of the value, to the point where the transmitter is quickly activated by your voice, without background noise causing the transmitter to activate.
- Press the [FUNC] knob, or wait for about 3 seconds, to save the setting.
- Press the [BACK] key several times to return to normal operation.
可调整 VOX 增益，以避免在嘈杂环境中误触发发射。
- 按住 [FUNC] 旋钮。
- 触摸 [VOX GAIN]。
- 一边对着麦克风或蓝牙耳机说话，一边旋转 [FUNC] 旋钮，或触摸数值两侧的 "<" / ">"，调到"说话能迅速触发发射、而背景噪声不会触发发射"的那一点。
- 按 [FUNC] 旋钮，或等待约 3 秒，保存设置。
- 多次按 [BACK] 键返回正常工作状态。
32.5 设置 VOX 延时Setting the VOX Delay Time
During transmissions using the VOX (Voice Operated Transmit) function, set the time to return to receive when speaking is paused:
- Press and hold the [FUNC] knob.
- Touch [VOX DELAY].
- Rotate the [FUNC] knob to select the delay time (the transmit-receive delay after the cessation of speech).
- Press the [FUNC] knob, or wait for about 3 seconds, to save the setting.
- Press the [BACK] key several times to return to normal operation.
使用 VOX（声控发射）功能发射时，可设置说话停顿后回到接收的延时时间：
- 按住 [FUNC] 旋钮。
- 触摸 [VOX DELAY]。
- 旋转 [FUNC] 旋钮，选择延时时间（说话停止后的收发转换延时）。
- 按 [FUNC] 旋钮，或等待约 3 秒，保存设置。
- 多次按 [BACK] 键返回正常工作状态。
