ADJUSTMENT /
调整
■ 下面是调整时所需的部件
1. 天线接口转换头
此手持机的天线接口使用 SMA 终端。
使用天线接口转换头 [ SMA ( f ) - BNC ( f ) 或 SMA ( f ) - N ( f ) ]进
行调整。
（转换头不作为可选件提供，因此请购买商用转换头。）
2. 维修机架（机壳）
使用机壳（A10-4086-03）维修 TK-2207。将 TX-RX 单元放置
在机壳上，并且拧上螺钉。
在维修过程中，需要在 TX-RX 单元的电路板上检测电压时，
机壳可以方便地进行电压检测，并且保护模块。

The following parts are required for
adjustment
1. Antenna connector adapter
The antenna connector of this radio uses an SMA terminal.
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.)
2. Repair Jig (Chassis)
Use jig (part No.: A10-4086-03) for repairing the TK-2207.
Place the TX-RX unit on the jig and fit it with screws.
The jig facilitates the voltage check and protects the final
amplifier FET when the voltage on the flow side of the TX-RX
unit is checked during repairs.
3. Battery Jig (W05-1011-00)
Connect the power cable properly between the battery jig
installed in the transceiver and the power supply, and be sure
output voltage and the power supply polarity prior to switching
the power supply ON, otherwise over voltage and reverse
connection may damage the transceiver, or the power supply
or both.
Note:
When using the battery jig, you must measure the
voltage at the terminals of the battery jig. Otherwise, a slight
voltage drop may occur within the power cable, between the
power supply and the battery jig, especially while the
transceiver transmits.
3. 电池夹具 (W05-1011-00)
在手持机的电池夹具和电源之间连接适当的电源电缆，确认
了输出电压之后接通电源开关，电压超过或极性颠倒都有可能
损坏手持机。
注∶
当使用电池夹具时，你必须测定电池夹具的终端电压。
因为，电源和电池夹具之间会有一些的电压下降，尤其在手持
机发射的时候。
