Which level of IP rating do you need for your radio?
IP Rating represents the level of protection provided by a device against the intrusion of solid objects and liquids. As radios are often used in a wide range of outdoor scenarios, many of them have IP ratings that tell users in which environment they can use them safely.
The IP code consists of two digits, e.g. IP67
The first digit indicates the level of protection against solid particle.
The second digit indicates the level of protection against liquid.
