hgdera td 370对讲机使用说明
Hytera 同频中继这样玩！（设置和技巧）自从 Hytera 推出了具备同频中继机能的 PD-980 之后，PA 发现了如果联合 Hytera 自家一个特别有的机能：虚拟集群，就可以实现：如果同频中继启动，用户自动使用中继，增加通信距离或覆盖纵深、同频中继关闭（如没电），用户自动进入直通，全程自适应，不需要人为干扰。
暂时由于机能设计的先进特性，只有 Hytera 的设备可以实现。
关键点：第一，用户的设置。
要使用上述同频中继自适应机能，只需在CPS写频软件中，设置收发频率必须同频，然后，写入数字频道的各项设置时，把 [ 时隙 ] 选择为 [ 虚拟集群 ] ，虚拟集群指定发射时隙设置为1，没有了，就这样简单。
（所有的用户都这样设置）
第二，同频中继的设置。
同上设置，唯一不同是虚拟集群指定发射时隙，该项机能选择默认的：无，完成。
原理：由于默认大家都处于时隙1通信，关闭同频中继，这时候彼此工作于直频，都能通，同频中继启动后，就把接收到的1时隙向2时隙转发，由于用户设置了虚拟集群，因此自动扫描两条时隙，既可以接收直达的时隙1信号，亦能接收经转发的时隙2信号。
海能达 DMR/PDT 数字对讲机选购指南，帮助安保公司根据所需功能和应用，选择合适的对讲机。
对讲机作为安保人员不可或缺的工具和至关重要的安全设备。
日常工作时间安保人员可与指挥人员及团队其他成员保持密切联系，在紧急情况下，灵敏便捷的即按即说 (PTT) 技术可以提供即时语音通信。
海能达数字对讲机具备多种功能，确保员工安全无虞，如“紧急”警报按钮、单独作业模式、倒地报警和 GPS 定位等功能。
（警报可以通过语音、文本或提示音的形式发出。
）GPS 定位功能令指挥人员和团队成员能够快速确定涉险安保人员的位置，并提供援助，紧急情况下设备会触发定位，向整个对讲机系统发送警报，同时传递触发警报者的身份信息。
这些功能与执勤的安保人员的安全息息相关，也有助于雇主履行健康安全条例责任。
坚固耐用客户还需要考虑安保人员所持对讲机的坚固程度。
在建筑物内工作的用户可能不需要高度防尘防水的对讲机，但仍需要高度防撞击和防跌落的设备。
如果您想从较低配置的海能达手持式移动设备入手，那么配备“紧急”警报按钮及单独作业功能的 PD500和PD560可以满足您的需求。
TD580(G) 提供带 GPS 和蓝牙选项的低配对讲机，而TD510则集成 RFID 读写器，内置海能达巡查解决方案，可实现简单的资产标记和跟踪。
上述产品的防尘防水等级为 IP54，是广受欢迎的室内安保对讲机。
不过，鉴于安保人员的工作环境有时非常恶劣，因此，这些产品或许不是户外使用的最佳选择。
除了 PD 6 和 PD 7 系列提供的紧急按钮和单独作业模式以外，如果您还需要额外的倒地报警及 GPS 定位等安全功能，可以选择 PD600、 PD660、 PD680、 PD700、以及 PD780的（G）版本。
这些更高配置的对讲机防护等级达 IP67 级，可用于DMR/PDT集群系统。
这些产品功能丰富，坚固耐用，是当今市场上性价比极高的安保对讲机。
不过，海能达顶级配置的安全对讲机非PD980莫属。
解析海能达三防对讲机PD680强悍的三防对讲机提起诺基亚早期的手机，相信许多人第一个想到的就是其坚固的机身，不管是用来砸核桃还是防身，它都是一个不错的选择。
然而今天我们为大家介绍的这款通讯工具，在机身的坚固程度上，有着更强悍的表现，这就是海能达旗下的数字对讲机——PD680。
由于对讲机的使用环境，几乎都是各种条件恶劣的户外行业，除了潮湿闷热以外，还有可能是寒冷的高原地带，所以在机身坚固程度和防护设计上，对讲机比普通的手机需要更加严格的标准和规范。
而本篇文章为大家介绍的这款海能达PD680数字对讲机，就是一款防范等级符合IP67，同时品质严格符合美国军用标准MIL-STD-810G的产品。
相信不少人都对IP67防护等级有一定的了解，其中的6表示产品对固态颗粒，也就是尘土沙子等较小物体的防护级别，6代表可完全防止灰尘的进入，而后面的数字7代表可以在1米深的水中浸泡30分钟之内，产品可以正常工作的标准。
所以对于以户外为主要使用场景的对讲机而言，IP67几乎可以满足绝大多数的恶劣环境。
虽然对于一般产品而言，IP67防护等级基本可以代表不俗的防尘防水能力，但是这款PD680，为了具有更强悍的表现，还符合美国军用标准MIL-STD-810 G级别的最高标准。
简单来说，MIL-STD-810G标准是美国评判装备在湿热环境中表现的军标，对于耐高温低温、防水防摔性都提出了很高的要求，最后一个字母“G”意味着其已经达到了很高的等级。
所以从综合表现上来看，这款海能达PD680的表现还是非常强悍的，几乎可以在任何高温低温、潮湿恶劣的环境中正常工作。
金属超薄机身设计在多数人印象中，具有出色三防能力的产品相对而言都要有着非常臃肿的身材，无论是三防手机还是其他电子产品，总是比常规产品看起来更加笨重。
然而海能达PD680在机身设计上，却有着更为轻薄的表现。
虽然使用了全金属机身设计，但无论是厚度还是重量，甚至优于其他不具有三防特点的常规对讲机。
