Celestron TetraView 44349 User manual

1
Thank you for purchasing the Celestron TetraViewTM LCD Digital
Microscope with a 4.3-inch touch screen monitor. Your microscope
is a precision optical instrument, made of the highest quality
materials. It is designed to give you a lifetime of enjoyment with
minimal maintenance.
Before attempting to use your microscope, please download and read
through the instructions from celestron.com to familiarize yourself
with its functions and operations. See the microscope diagram to locate
the parts discussed in this manual.
This microscope provides high powers from 40x up to 400x (up
to 1600x with digital zoom). This microscope is mainly suited for
examining specimen slides of yeasts and molds, cultures, plant and
animal parts, fibers, bacteria, and more.
Unlike traditional microscopes, the Celestron TetraViewTM LCD Digital
Microscope does not use eyepieces. You will view specimens on the
LCD screen. In addition, you can take snapshots or short videos with
the built-in digital camera. Plus, you can view on most TV screens with
the AV/TV cable.
