4. Wireless Clone Mode
4-1. Outline
“Wireless Clone Mode” copies the transceiver data to an-
other transceiver.
The dealer can copy the transceiver data to another
transceiver even without the use of a personal computer.
4-2. Example
The transceiver can copy the programming data to one or
more transceivers via RF communication.
The clone source and clone target/s must be in wireless
clone mode.
4-3. Operation
1. To switch the clone target/s to Wireless Clone mode,
press and hold the [<B] key while turning the transceiver
power ON.
2. Wait for 2 seconds. “CLONE” appears on the LCD, followed by “FRQTBL 1”.
3. Select a channel table number using the [Selector] knob.
4. To switch the clone source to Wireless Clone mode,
press and hold the [<B] key while turning the transceiver
power ON.
5. Wait for 2 seconds. “CLONE” appears on the LCD, followed by “FRQTBL 1”.
6. Select the same channel table number as the clone target/s.
7. Press the [S] key on the clone master to begin data transmission. When the clone target starts to receive data, the
green LED will light and “CLONING” will appear on the
LCD. The source unit will display “MASTER”.
8. When the clone source fi nishes sending data, a “confi rmation” tone will sound and “COMPLETE” will appear on
the LCD. If data transmission failed while cloning, the target unit will produced an error tone and “CLONE NG” will
appear on the LCD.
9. If the cloning fails, no data will be available in the target
unit when it is returned to User mode.
10. When the cloning is successful, the target unit's “Scan”
and “Key lock” functions will return to their default values
(Scan = OFF, Key lock = OFF).
11. The source will remain in clone mode after cloning. The
target unit will return to user mode after a successful
cloning.
Note:
• The dealer can clone data to two or more transceivers by
repeating the above procedures.
• If the transceivers wireless clone Mode is confi gured as
“Disabled”, the transceiver cannot enter Clone mode.
• The table shown below will cover the frequency tables
used for wireless cloning.
• Wireless clone mode cannot be entered in battery low
state.
• A unit cannot be a “Source Unit” if it is unprogrammed. If
the [S] key is pressed, an “error” tone will sound.
• Once a unit is set to be the source, it cannot be a target
after the data has been transmitted. This protects the
data in the source unit.
• MSK signaling is used in cloning.

4-3. 操作方法
1. 将子机切换到无线复制模式，接通 (ON) 手持对讲机电源
开关的同时，持续按 [<B] 键。
2. 等待 2 秒。LCD 上显示“CLONE”，然后显示“FRQTBL 1”。
3. 用 [ 选择器 ] 旋钮选择频率表号码。
4. 将主机切换到无线复制模式，打开手持对讲机电源 (ON)
的同时，持续按 [<B] 键。
5. 等待 2 秒。在 LCD 上显示“CLONE”，然后显示“FRQTBL 1”。
6. 选择与复制子机相同的频率表号码。
7. 按复制主机上的 [S] 键，开始传输数据。当复制子机开接
收数据时，绿色 LED 将亮灯，并且“CLONING”显示在 LCD 上。
主机将显示出“MASTER”。
8. 当复制主机完成数据传送，将发出一个“确认”音，并且
在 LCD 上显示出“COMPLETE”。如果复制中数据通讯失败，
子机将发出错误音，而且在 LCD 上显示出“CLONE NG”。
9. 如果复制失败，子机回到用户模式时会无可用数据。
10. 当复制成功时，子机的“扫描”和“键锁定”功能将返回
到它们的初始值 ( 扫描＝ OFF，键锁定＝ OFF)。
11. 主机在复制后将停留在复制模式。复制成功后，子机将返
回到用户模式。
注∶
• 经销上可以把同样的数据反复地复制到两台或更多的手持
对讲机。
• 如果手持对讲机的无复制模式被设定为“禁用”，则手持
对讲机不能进入复制模式。
• 此表是使用于无线复制的频率表。
• 在电池低电压状态时，不能进入无复制模式。
• 如果没有被编程，就不能成为“主机”。如果 [ S] 键被按，
将会发出“错误”音。
• 手持对讲机一旦被设定为主机，而且数据被传送之后，它
就不能成为子机。此功能是为了保护主机内的数据。
• MSK 信号用于复制。
• 电子干扰有可能导致无线复制时数据传送失败，如在工作
台上受到电波或电磁的干扰。

2-1. Front End (RF Amplifi er) Circuit
The signal coming from the antenna passes through the
transmit / receive switching diode circuit (D201, D202, D203
and D204) and a BPF (L418 and L419), and is then amplifi ed by the RF amplifi er (Q407).
The resulting signal passes through a BPF (L419, L418,
L416 and L414) and goes to the mixer. These BPFs are adjusted by variable capacitance diodes (D408, D407, D405
and D404). The input voltage to the variable capacitance
diodes is a regulated voltage output from the DC amplifi er
(IC811).
