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

25、one or more transceivers via RF communication. The clone master and clone slave/s must be in Clone mode. 4-3. Operation 1. To switch the clone slave/s to Clone mode, press and hold the PTT and side2 keys while turning the transceiver power ON. 2. Wait for 2 seconds. The LED will light orange and the

26、 transceiver will announce Clone. 3. Select a channel table number using Side1(increment channel table) and Side2(decrement channnel table) keys. 4. To switch the clone master to Clone mode, press and hold the PTT and side2 keys while turning the transceiver power ON. 5. Wait for 2 seconds. The LED

27、will light orange and the transceiver will announce Clone. 6.Select the same channel table number as the clone slave/s. 7. Press PTT on the clone master to begin data transmission. When the clone slave starts to receive data, the LED will light green. When the clone master finishes sending data, a c

If data transmission fails while cloning, an error tone will sound from the Slave unit. 4. 复制模式 4-1 概要 “复制模式”可以将一台手持机的数据复制到其它的手持机。 经销商甚至不使用个人电脑也可以将一台手持机的数据复制 到其它的手持机。 4-2 例: 手持机可以通过 RF 通信复制编程数据到一台或更多的手持 机。 复制主机和复制子机必须处于复制模式。 4-3 操作方法 1. 将子机切换到复制模式，旋转手持机电源的同时，持续按 PTT 键和 侧

29、2 键。 2. 等待2秒。 LED将呈橘黄色并且手持机将发出复制的声音。 3. 用侧 1 (频道表递增) 键和侧 2 (频道表递减) 键选择频道表号 码。 4. 将主机切换到复制模式，旋转手持机电源的同时，持续按 PTT 键和 侧2 键。 5. 等待2秒。 LED将呈橘黄色并且手持机将发出复制的声音。 6. 选择与复制子机相同的频道表号码。 7. 按复制主机上的 PTT，开始数据传输。 当复制子机开始接收数据时，LED 将呈绿色。 当复制主机完成传送数据时，将发出一个“确认”音。 如果在复制过程中数据传输失败， 子机将发出一个错误音。 8. 如果复制失败，子机回到用户模式时数据随即消失。 9.

30、 当复制成功时，子机的扫描和键锁定功能将回到它们 的初始值 (扫描=OFF, 键锁定=OFF) TK-2207 6 REALIGNMENT / 模式组合 Clone Frequency Table Operating Frequency Clone(MHz)136174 Frequency Table 1136.000 2138.000 3140.000 4142.000 5144.000 6146.000 7148.000 8150.000 9152.000 10154.000 11156.000 12158.000 13160.000 14162.000 15164.000 16166.0

If the cloning fails, no data will

32、 be available in the Slave unit when it is returned to User mode. 9. When the cloning is successful, the Slave units Scan and Key lock functions will return to their default values (Scan = OFF, Key lock = OFF). Notes: The dealer can clone data to two or more transceivers by repeating the above proce

33、dures. If the transceivers Clone Mode is configured as Disabled, the transceiver cannot enter Clone mode. The table shown below will cover the frequency tables used for wireless cloning. Clone mode cannot be entered in battery low state. A unit cannot be a Master Unit if it is unprogrammed. If PTT i

34、s pressed, an error tone will sound. The language used in cloning depends on the Model type setting, not the FPU setting. C, C2, C5 and C6 type TK-3207 transceivers will use Chinese. Other types English. Once a unit is set to be the Master, it cannot be a slave after the data has been transmitted. T

35、his protects the data in the Master unit. Electronic interface may cause a failure in data transfer during Wireless Clone, such as when waveforms or electromagnetics are being performed at the workbench. Clone mode can be used ONLY by the authorized service personnel. The Clone mode setting must be

36、configured as Disable before being delivered to the end-user. To clone, replace the antenna from both the master transceiver and the slave transceiver with a dummy load. The transmit output power is automatically set to Low in Clone mode. 注释： 经销商可以反复上述过程复制数据到2个或更多的手持机。 如果手持机复制模式被设置为 “无效” ， 则手持机不能进入复

37、 制模式。 下表包含了无线复制用的频率表。 当电池处于低电压状态时不能进入复制模式。 如果手持机是非编程的它将不能成为主机。 如果按PTT， 将 发出一个错误 音。 复制时所用的语言是根据样机类别设置，而不是FPU设 置，TK-3207的C，C2，C5和C6 类别的手持机用中文，其它 类别用英文。 手持机一旦被设置为主机，数据传送以后，它就不能成为子 机。这是为了保护主机里的数据。 在无线复制的数据传输过程中， 例如在工作台产生的电波或 电磁干扰有可能引起传输失败。 复制模式可以仅被批准的服务人员使用。 在交付给最终用户之前，复制模式设置必须被设置为“无 效” 。 为了复制，将模拟负载代替主手

38、持机和子手持机的天线。 在复制模式，发射功率自动设定为低。 TK-2207 7 DISASSEMBLY FOR REPAIR / 维修拆卸 Removing the case assembly from the chassis. 1. Remove the volume knob z and channel knob x. 2. Remove the two screws c. 3.
