Panel Tuning Mode
■ Preparations for tuning the transceiver
Before attempting to tune the transceiver, connect the
unit to a suitable power supply.
Whenever the transmitter is turned, the unit must be
connected to a suitable dummy load (i.e. power meter).
The speaker output connector must be terminated with
a 4Ω dummy load and connected to an AC voltmeter and an
audio distortion meter or a SINAD measurement meter at all
times during tuning.
■ Transceiver tuning (To enter tuning mode)
To enter tuning mode, press the [ ] key while the trans-
ceiver is in test mode. Use the [ ] key to write tuning data
through tuning modes, and the [ ]/[ ] key to adjust tuning
requirements (1 to 4096 appears on the LCD).
Use the [
] key to select the adjustment item through
tuning modes. Use the [ ] key to adjust 5 reference level
adjustments, and use the [ ] key to switch between Wide/
Narrow/Very narrow.

面板调谐模式
■ 调谐车载对讲机的准备
在尝试调谐车载对讲机前,请将车载对讲机连接到合适的
电源上。
发射打开时, 车载对讲机必须连接到合适的等效负载上 ( 如
功率表 )。
扬声器输出连接器必须端接 4Ω 的等效负载,调谐期间,
必须始终连接到交流电压表和音频失真仪或 S I N A D 测量仪表
上。
■ 车载对讲机调谐 ( 进入调谐模式 )
要进入调谐模式,请在车载对讲机处于测试模式时按 [ ]
键。用 [
] 键写入调谐模式的调谐数据,用 [
调整调谐要求 (LCD 上出现 1 到 4096)。
用 [
] 键选择调谐模式的调整项目。用 [
点基准电平调整,然后用 [ ] 键切换宽 / 窄 / 超窄。
