Precautions
NVS 7 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.
