PRECAUTIONS
NV66-G2 is a sophisticated precise optical instrument
equipped with electronics. It should be handled with due
care:
 Unit contains fragile components. Avoid impacts,
dust, moisture and sharp changes of temperature.
 Do not touch the optical surfaces other than for
cleaning. Doing so may damage the anti-reflection
coating.
 Clean optical surfaces with professional lens cleaning
supplies.
 Use only a soft clean cloth to clean the exterior of the
device.
 Keep the device away from sources of heat, such as
heating appliances, sunlight or central heating.
 Switch off the unit and remove the battery during the
extended periods of non-operation.
 Do not apply an excessive force or pressure to the lens
assembly, movable parts and thread connections.
 Small dark and/or light spots may be seen in the field
of view due to considerable optical magnification of
the eyepiece. This does not affect the operational
capabilities of the device
