Radio wave radiation The influence on the environment of radio wave radiation ❏ The Radio Frequency module that can be installed in this product radiates the same high frequency energy as some other high frequency devices but the level of the energy radiated from it is suppressed so that it is much lower than the electromagnetic energy radiated from radio equipment like cell phones. ❏ Under some situations and in certain environments, the use of this equipment is sometimes limited by the owner of the building or a representative with responsibility for the group. For example, it may be restricted in the following case: • Use in an environment where it may cause interference with other devices and services. ❏ If you do not understand the radio device usage policy in a specific group or environment, such as an airport, ask permission before turning on the power of this product.
