## What is Opus LF?

Opus LF is a personal alarm in your mobile phone. With Opus LF you can easily alert pre-selected receivers who can watch the emergency situation via real time video streaming and follow your location in order to speed response.

The app requires login information for use. If you have forgotten your information, we recommend that you contact the Opus LF responsible person to retrieve your information.

Continued use of GPS running in the background can dramatically decrease battery life.
