How to Use Your TryThrive Egg Cooker

Congratulations on your new Olera™ 4-in-1 C.O Monitor—the easiest way to protect your family from silent killers!

Step 1: Choose Your Location

  • Place the monitor on a flat surface or plug directly into a wall outlet near sleeping areas or gas appliances.
  • Keep it at least 5 feet away from fuel-burning appliances for accurate readings.

Step 2: Plug In & Auto-Calibrate

  • Simply plug the monitor into any standard AC outlet.
  • The device will automatically begin calibrating (takes 2-3 minutes).
  • Wait for the display to show "0" readings before leaving the area.

Step 3: Verify It's Working

  • Check the digital display—you should see:

    CO Level: Should read "0" in safe conditions
    Gas Level: Should read "0" in safe conditions
    Temperature: Current room temperature
    Humidity: Current relative humidity percentage

Step 4: Test the Alarm

  • Press and hold the test button for 3 seconds.
  • You'll hear the loud 85dB alarm—this confirms it's working properly.
  • Test weekly for peace of mind.

Step 5: Stay Protected

  • The monitor continuously tracks air quality 24/7.
  • If dangerous levels are detected, the alarm will sound immediately.
  • Evacuate and ventilate the area, then contact emergency services if CO or gas is detected.

Safety & Care Tips

  • Do not cover the sensor vents on the device.
  • Always keep plugged in for continuous protection.
  • Wipe with a soft, dry cloth monthly to keep sensors clear.
  • Never use harsh chemicals or immerse in water.
