REM-Fit Active 200 devices with a screen have a feature called TwinkleTorch that will make the entire REM-Fit Active display light up for 1-20 seconds. This is especially useful when you need light in the middle of the night to make it to the restroom. :)
To enable TwinkleTorch, simple press the display for 5-10 seconds until the light comes on. The default setting is for the TwinkleTorch to stay lit for 10 seconds. You can adjust the amount of time in the settings menu.
1. Click on the Setting Menu (the three stacked lines in the top left corner of the app).
2.Select "Settings" Settings then "TwinkleTorch"
3. Configure theTwinkleTorch and click save.
