For best performance, keep the device in a dry place when not in
use. Long-term exposure to high humidity environment will cause
irrecoverable damage to the activation mechanism.
Warning!
After transportation or keeping the device at temperature lower than -
25°C (-13°F), the device must be warmed up to an ambient temperature,
from -20°C (-4°F) to +40°C (104°F) during 2-3 hours.
Precaution
Stargate M is a precision optical instrument equipped with electronics.
Therefore, it should be handled with due care:
• Keep your device away from direct sunlight, impacts, dust, moisture,
and sudden changes of temperatures.
• Do not touch the optical surfaces with fingers. Doing so may damage
the anti-reflection coating.
• Cleaning of optical surfaces is possible only with professional camera
lens cleaning supplies.
• To clean the exterior of the device, use only a soft clean cloth.
• Do not take the cover off the lens if not necessary.
• Keep away from heating appliances and central heating.
• Do not apply superfluous efforts at work with lens assembly, agile
elements and thread connections.
• Due to considerable optical magnification of the eye-piece some small
structures inside the tube coating in the form of dark and/or white
points may be seen in the field of view which does not affect the
serviceability of the device;
• The resolving power (resolution) may change in the direction from the
center towards the perimeter of the field of view. This is an inherent
feature of the image intensifier tube type utilized in the device. We
would recommend placing the scene of observation in the center of
the field of view.
