IEC 62106:2000 频率范围为87.5～108.0MHz的VHF/FM声音广播用无线电数据系统(RDS)的规范

The Radio Data System, RDS, is intended for application to VHF/FM sound broadcasts in the range 87.5 MHz to 108.0 MHz which may carry either stereophonic (pilot-tone system) or monophonic programmes. The main objectives of RDS are to enable improved funtionality for FM receivers and to make them more user-friendly by using features such as Programme Identification, Programme Service name display and where applicable, automatic tuning for portable and car radios, in particular. The relevant basic tuning and switching information therefore has to be implemented by the type 0 group (see 3.1.5.1), and it is not optional unlike many of the other possible features in RDS.

Covers fusing resistors and temperature-limited resistors to be employed in radio and television-type appliances. These requirements also apply to resistor-mounting assemblies intended for use with such resistors. The purpose of these requirements is to reduce the risk of fire or electric shock by use of those resistors, but compliance of a resistor with the following requirements does not mean that it is acceptable for all applications without evaluation in the appliance.
