IMPORTANT SAFETY INFORMATION
Environmental inuences
• Note: Never point the lens of the device directly at intense heat sources such
as thesun or laser equipment. The objective lens and eyepiece can function
as aburning glass and damage the interior components.
• Caution: Avoid touching the metal surface (cooling ns) after exposure
to sunlight or cold.
• Caution: Protection class IP66 is only achieved when all rubber covers are
rmly closed.
Ergonomics note
Caution: Take breaks after longer periods of use to avoid wrist pain.
Risk of swallowing
