主要功能：
提供准确的反极性信号。
的来电显示：提供显示来电的功能。 连接的电话必须具有显示来电呼叫的功能。
自动添加放在前面的代码：终端设置可以设置为拨打本地固定电话时，添加本地区号拨打长途电话时，添加IP放在前面的代码。
锁定无线终端，锁定的SIM卡，锁定服务提供商和锁定区：所有的这些功能​​可设置根据用户的要求。 锁定终端意味着终端仅可以识别安装在终端时锁定端子设置，且设置是有效的SIM卡。 锁定SIM卡意味着只能在该锁定的SIM卡对应终端所使用的锁定的SIM卡被设置并且是有效的。 锁定服务提供商可以禁止在所述终端使用不属于到锁定服务提供商的SIM卡。 锁定区的数量可以是终端可以搜索自己的地区周围，如果自动锁定分区设置的数字从1至6。 然后，终端可以只在锁定区被使用。
网络管理：网络管理系统可以通过发送和接收的短消息，诸如推求参数交换与无线终端的数据，修改参数，报告故障等。 远程管理实现的，无需操作人员去现场进行维修。
参数管理：参数可以由用户通过连接的电话键盘进行修改的手。 输入通过输入正确的密码设置程序。 进入设置程序后，用户可以更改与给定的命令参数。
电话号码代码管理：禁止的代码，直接传输代码，本地移动电话区号和长途码可设置方便。
快速发送的电话号码：根据服务提供者的标准，所拨号码可以传送6秒以后，因为电话号码的最后一位数字被按压。 有些客户认为6S的等待时间过长。 为了满足用户的要求，以缩短等待时间，快速发射的电话号码的功能显影。 的快速传输的电话号码的列表可以成立。 该设置将保存四条秒来等待时间为用户的每个拨号快速发射的电话号码。
支付任何内部电话（可选）：连接到同一个终端可以相互调用，而不使用移动电话网络和用户无需支付任何东西这类呼叫的电话。 功能和用法都一样到PBX。
恢复参数：所有参数可以设置为它们设置了当终端离开工厂缺省值。
设置或取消呼叫转移
调节音色的音量：麦克风音量和扬声器音量可单独调节。

Main function:
Provide accurate anti-polarity signal.
Incoming calls display: Offer the function of displaying incoming calls. The connected telephone must have the function of displaying incoming calls.
Add prefixal code automatically: The terminal setting can be set to add the local area code when dialing local fixed calls and add IP prefixal code when dialing long-distance calls.
Locking wireless terminal, Locking SIM card, locking service provider and locking districts: All these functions can be set up according to the customers requirement. Locking terminal means that the terminal only can identify the SIM card that is installed in the terminal when locking terminal is set up and the setting is effective . Locking SIM card means that the locked SIM card only can be used in the corresponding terminal in that locking SIM card is set and is effective . Locking service provider can forbid the SIM card that doesn't belong to the locked service provider to be used in the terminal. The number of locked districts can be the digits from 1 to 6. The terminal can search for districts around itself automatically if locking district is set up. Then the terminal only can be used in the locked districts.
Network Management: The network management system can exchange data with wireless terminal through sending and receiving short message, such as inquire parameters, modify the parameters, report malfunction and so on. Long-distance management is realized and needn't operator go to the scene to make maintenance.
Parameter management: Parameters can be modified by users by hand through the keyboard of the connected telephone. Enter setting program by inputting correct passwords. After entering setting program, users can change parameters with the given orders.
Telephone numbers code management: Barred code, directly transmit code, local mobile telephone code and long-distance code can be set up conveniently.
Fast transmit telephone numbers: According to the standard of the service provider, the dialed numbers will be transmitted 6s later since the last digit of the telephone numbers is pressed . Some customers think the waiting time of 6s is too long. In order to meet the users requirement to shorten the waiting time, the function of fast transmit telephone numbers is developed. The list of fast transmit telephone numbers can be set up. This setting will save 4 seconds waiting time for the users for dialing every fast transmit telephone numbers.
Pay nothing for internal calls (optional) : The telephones that are connected to the same terminal can call each other without using the mobile telephone network and the users need not pay any things for this kind of call. The functions and use are the same to PBX.
Resume parameters: All the parameters can be set up to be the default value which are set up when the terminal left the factory.
Set up or cancel call diverting
Adjusting the Volume of Voice : microphone volume and speaker volume can be adjusted separately.
