Two way radios are often used outdoors and may sometimes be exposed to moisture or even harsh weather conditions. When choosing a radio, it is important to consider how well it can withstand exposure to water. One of the standards used to rate water resistance is the JIS rating.

In this episode of Radio 101, Rick explains in simple terms what the JIS rating system is and how it works to determine the water resistance of two way radios.
