■ Antenna connector adapter
The antenna connector of this radio uses an SMA termi-
nal. Use an antenna connector adapter [SMA(f) – BNC(f) or
SMA(f) – N(f)] for adjustment. (The adapter is not provided
as an option, so buy a commercially-available one.)
Note:
When the antenna connector adapter touches the knob,
draw out the knob to mount the connector.
■ Universal connector
Use the interface cable (KPG-36) for PC tuning or the lead
wire with plug (E30-3287-28) and screw (N08-0535-08) for
panel tuning. Connect the plug to the universal connector of
the radio and tighten the screw.
The lead wire with plug (E30-3287-28) and screw (N08-
0535-08) terminals are as follows. Numbers are universal
connector terminal numbers.
Caution:
1. When connecting the plug to the universal connector of
the radio, a short circuit may occur. To prevent this, be
sure to turn the radio POWER switch off.
2. Since the RX AF output is a BTL output, there is a DC
component. Isolate this with a capacitor or transformer as
shown in the fi gure.
3. Do not connct an instrument between red or black and
GND.

■天线接口转换头
此对讲机的天线接口使用 S M A 终端。使用天线接口转换头
[SMA(f)- BNC(f) 或 SMA(f)- N(f)] 进行转换。( 转换头不作为
可选件提供，因此请购买商用转换头。)
注释 :
当天线接口转换头接触到其他旋钮时，拔出该旋钮并安装转
换头。
■通用接口
使用接口电缆 ( K P G -36) 进行 P C 机调谐或使用带有插头
(E30-3287-28) 和螺钉 (N08-0535-08) 的引线进行面板调谐。
带有插头 ( E30-3287-28) 和螺钉 ( N08-0535-08) 的引线端
点如下所示。号码是通用接口端子号码。
注意事项 :
1. 将插头与对讲机通用接口连接时，可能发生短路。为了避
免出现这种情况，一定要关闭对讲机的电源开关。
2. 由于 RX 音频输出是 BTL 输出，所以有一个直流分量。如图
所示，用电容或变压器将其隔离。
3. 在红色或黑色与接地之间不要连接仪器设备。
