After unpacking your microscope and before using it for the first time check for integrity
and durability of every component and connection. Do not try to disassemble the device on
your own for any reason. For repairs and cleaning of any kind, please contact your local
specialized service center. Protect the device from sudden impact and excessive
mechanical force. Do not apply excessive pressure when adjusting focus. Do not
overtighten the locking screws. Do not touch the optical surfaces with your fingers. To
clean the device exterior, use only special cleaning wipes and special optics cleaning tools
