An Important Note About Sun Safety...
You'll need to spend up to half a day in the Sun to
calibrate the TERC VHS-1. Half a day in the Sun can cause fair-skinned people to get a sun burn, so be sure to wear long sleeves
and rub sun screen on exposed skin if you are susceptible. No
matter what shade or color your skin is, be sure to wear a hat
and sunglasses to protect your eyes from the ultraviolet
radiation (UV-B) scattered from the sky. Skin color doesn't
matter when it comes to protecting your eyes from dangerous UV-B!
WARNING: AVOID DAMAGE TO YOUR EYES! NEVER LOOK AT THE SUN, EVEN WHILE WEARING SUNGLASSES! ALWAYS WEAR SUNGLASSES WHEN LOOKING AT THE SKY!
