Precautions
All NVS 14 series devices are sophisticated electro-optical
instruments. They should be handled with due care:
Each Unit contains fragile components. Avoid hard impacts,
dust, moisture and abrupt changes of temperature.
Do not touch the optical surfaces other than for cleaning with
an appropriate lens cleaning kit. Doing so may damage the
anti-reflective 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 extended
periods of non-operation.
Do not apply excessive force or pressure to the lens assembly,
movable parts or threaded 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.
