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
