Precautions for Use (Please be sure to read before use)
ENG-4
Warning
(regarding the batteries)
1) Please carefully check the batteries as well as the package to verify the
nominal voltage rating of the batteries before use. Be sure not to use
batteries with a nominal voltage rating of 1.5V or higher or batteries
which have no nominal voltage information. Using such batteries may
result fire, generation of smoke, or personal injury.
2) In rare cases, some AA-size lithium batteries will reach extremely high
temperatures. For your safety, please refrain from using AA-size lithium
batteries.
3) Never attempt to disassemble batteries, charge the batteries (except for
Ni-MH rechargeable batteries), leave batteries in a hot place, short
circuit the contacts, or throw them into a fire. These actions can cause
battery leakage, ignitions, and explosions which may lead to fire or
personal injury. (Rechargeable batteries are batteries which can be
charged and reused many times.)
4) Always replace both batteries at the same time. In addition, please do
not use different brand batteries together or a new battery with an old
battery. Doing so can cause battery leakage, ignitions, and explosions
which may lead to fire or personal injury.
5) Please remove the batteries if the binoculars are not to be used for an
extended period or if the batteries have been depleted. If the batteries
are left inside, they may leak, causing malfunction, corrosion, or fire.
6) Insert the batteries with the + and – terminals in the correct directions.
Not doing so can cause battery leakage, ignitions, and explosions which
may lead to fire or personal injury.
Caution
(regarding the batteries)
7) If any liquid from inside the batteries leaks out and contacts your skin,
be sure to wash the liquid off thoroughly.
8) If the lamp does not light even when you press the Image Stabilizer
button, the battery power is low. Replace the batteries with two new
batteries at the same time from the same brand.
