Flashes
During the first two minutes after switching on
the scope, flashes may occur. If this flashing
continues the surrounding area may be too
bright. This can occur even with mounted lens
cap. In darker surroundings the flash occur-
rence will become less or cease completely.
The device fogs up
If the device is used at low temperatures and
is then suddenly exposed to a warmer ambient
temperature, condensation may develop on the
cold surface of the device. It can take a while
before the scope has acclimatized to the ambi-
ent temperature.
