Precautions
NVS 15 is a sophisticated precise optical instrument equipped
with electronics. It should be handled with due care:
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 unit 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.
