产品简介：

马兰仕HX370S VHF对讲机

HX-370S带有国际海事频道。它同样具有可被设计成带CTCSS的40个陆地移动广播(LMR)或商家设计的DCS信号。这些频道需要相应的许可批准.

HX370S可被设计成扫描带有或不带优先于频道16的任何频道数字。同时也包含了监控功能。PRESET键允许快捷地重选8个你非常常用的频道。

大液晶显示屏用频道的名字来告知你每个所选择的频道的用法。

在HX370S的顶部的防水中的插口允许连接可以选择的头戴式耳机或讲话话筒。

大容量电池：1400mAhL镍合金氢电池，高功率时，可工作14个小时(5／5／90)日常循环(TX／RX／备用)、同时也含有一个防水碱性电池盘．12VDC充电器，230VAC充电器和一个板面嵌入式充电。另外，在LCD上一个很容易看到电池寿命的指示器需要充电时提示你。

对讲机常规维护
对讲机使用安全注意事项

2、在潜在爆炸的大气环境或场合下，除非对讲机是通过特殊认证的，否则须关闭对讲机。在潜在爆炸大气环境中，电火花会导致爆炸或火灾。
3、不要在潜在爆炸的大气环境下更换电池或对电池充电。安装和拆卸电池时可能会引起接触电火花并导致爆炸。
4、在*近爆破区和雷管所在区域前，须先关闭对讲机，以免引起可能的爆炸。

影响对讲机通话距离和效果的因素有以下几个方面：

1、系统参数：

1）发射机输出功率越强，发射信号的覆盖范围越大，通信距离也越远。但发射功率也不能过大，发射功率过大，不仅耗电，影响功放元件寿命，而且干扰性强，影响他人的通话效果，还会产生辐射污染。各国的无线电管理机构对通信设备的发射功率都有明确规定。

2）通信机的接收灵敏度越高，通信距离就越远。

3）天线的增益，在天线与机器匹配时，通常情况，天线高度增加，接收或发射能力增强。手持对讲机所用天线一般为螺旋天线，其带宽和增益比其他种类的天线要小，更容易受人体影响。

2、环境因素：

环境因素主要有路径、树木的密度、环境的电磁干扰、建筑物、天气情况和地形差别等。这些因素和其他一些参数直接影响信号的场强和覆盖范围。

3、其它影响因素：

1）电池电量不足，当电池电量不足时，通话质量会变差。严重时，会有噪音出现，影响正常通话。

2）天线匹配，天线的频段和机器频段不一致，天线阻抗不匹配，都会严重影响通话距离。对于使用者来说，在换用天线时要注意将天线拧紧，另外不能随便使用非厂家提供的天线，也不能使用不符合机器频点的天线。

4、音质的好坏主要取决于预加重和去加重电路，目前还有较先进的语音处理电路"语音压扩电路和低水平扩张电路的应用"，这对于保真语音有很好的效果
