Note: This device is equipped with an
additional photosensor to prohibit the unit from
being turned on under a bright light source. If
the unit is to be tested in daylight with the lens
covers on, the photocell must be covered up.
Note: These devices utilize a high voltage
power supply and maintain a charge in a
capacitor and will continue to provide an
image until the capacitor is fully drained.

7. Maintenance
The user must take very good care of the
scope, protect it from impacts, dust and raw
conditions.
Do not rub objects against the lens and the
oculars. In the event that you get fingerprints,
dust or dirt on the lens, rub the optical surface
with a very soft scratch free cloth, soaked
slightly in alcohol.
8. Guidelines for storage and transport
The device must be stored in a warm, dry
place where the humidity does not exceed
80% and at a temperature of 65-90 degrees F.
The scope should only be shipped in a sturdy
container, with sufficient packing material to
prevent shock damage.
The box must be protected from any moisture
during transport.
Remove the batteries and store in a separate
location if the scope is not to be used for 10 or
more days.
