The information icon alerts the reader of important facts and conditions.
The tip icon indicates advice on, for example, how to design your project or
how to use a certain function.
Although warning hazards are related to personal injury, it is necessary to understand that
under certain operational conditions, operation of damaged equipment may result in
degraded process performance leading to personal injury or death. It is important that the
user fully complies with all warning and cautionary notices.
Operation of damaged equipment could, under certain operational conditions, result in
degraded process performance leading to information or property loss. Therefore, comply
fully with all notices.
