Cautionary Notes
For the Binoculars
(1) Never look at the sun or a bright light with the binoculars. Doing so
can cause loss of vision.
(2) If the binoculars are taken from a cold environment to a warm one,
condensation may develop on the surface and internal parts. To
prevent condensation, first put the binoculars into an airtight plastic
bag before taking it to a warm environment. Let it gradually adjust to
the warmer temperature, then take out the binoculars. Do the same
when taking the binoculars from a warm environment to a cold one.
(3) Binoculars are precision instruments. Do not drop them or subject
them to shock. Never attempt to disassemble them.
(4) The binoculars are not waterproof. Avoid exposing the binoculars to
rain or water spray.
(5) High temperatures can cause the binoculars to malfunction. Do not
store them close to a heater or in a closed car on a sunny day.

Battery Care
(1) Never attempt to disassemble batteries. Do not leave batteries in a hot
place or throw them into a fire. Do not short circuit the contacts. Doing
any of the above is highly dangerous.
(2) You should never mix different types of batteries. When changing
exhausted batteries, replace them all at once.
(3) Although lithium batteries work well in low temperature, their
performance will drop slightly in temperatures below 0 degrees C. In
cold locations, keep a spare set of batteries in a warm pocket and
alternate them with the batteries in use.
