本文件规定了便携式设备所需的最低技术特性和测量方法 不提供海上遇险和安全通信功能的甚高频（VHF）无线电话 （即不构成全球海上遇险和安全系统（GMDSS）的一部分）以特定频率运行 使用25 kHz和12.5 kHz信道分配给海上移动服务的频带。本文件旨在涵盖指令1999/5/EC[1]（R&TTE指令）第3.2条的规定， 其中规定:“无线电设备的构造应确保其有效使用分配给 地面/空间无线电通信和轨道资源，以避免有害干扰”。除本文件外，其他欧洲标准规定了基本要求方面的技术要求 根据R&TTE指令第3条的其他部分，指令[1]可适用于本法规范围内的设备 文件

The present document states the minimum technical characteristics and methods of measurement required for portable Very High Frequency (VHF) radiotelephones not providing maritime distress and safety communications functions (i.e. not forming part of the Global Maritime Distress and Safety System (GMDSS)) operating in certain frequency bands allocated to the maritime mobile service using both 25 kHz and 12,5 kHz channels.The present document is intended to cover the provisions of Directive 1999/5/EC [1] (R&TTE Directive) Article 3.2, which states that ".radio equipment shall be so constructed that it effectively uses the spectrum allocated to terrestrial/space radio communications and orbital resources so as to avoid harmful interference".In addition to the present document, other ENs that specify technical requirements in respect of essential requirements under other parts of Article 3 of the R&TTE Directive [1] may apply to equipment within the scope of the present document.
