LIGHT PROTECTION SENSOR:
Please note that the unit is equipped with the special protection
sensor (7), which would not allow you to turn on the unit without
the lens cover in a well-lit area. To test the unit during daylight
(only with the lens covers on) you may cover the sensor with
your finger or move to a darker area.
Please note that the
protection sensor only works when turning the unit on
and does not protect the unit from accidental exposure to
a bright light once the unit is already powered up. Please
avoid such exposure to preserve the full life of the tube.
TROUBLESHOOTING:
1.
Unit does not turn on and the light indicator is off:
a)
please check if the batteries are inserted according
to the diagram
b)
please make sure the batteries are fresh
2.
The light indicator is working, but you cannot see the
image:
a)
you may be turning the unit on in a well-lit area
and the protection sensor is activated
b)
you may be turning the unit on in a dark area with
the lens covers still on the unit
c)
You may need to turn on the infrared light
d)
please make sure the batteries are fresh – it takes
a lot less power to turn on the little red indicator,
than the entire unit
3.
Unable to obtain sharp and clear image:
a)
you may need to repeat the process of rotating the
oculars and objective lenses several times until you
get a good feel of it – adjust one eye at a time
b)

the minimum focusing distance is approximately
25cm or 10 inches
c)

may clean them with soft lens cleaning cloth
