Use only the specified batteries. (see page 14)
Be sure to observe the following points. Otherwise, battery fluid leak, overheating, fire ignition and/or bursting may
result.
•Do not mix old and new batteries, recharged and discharged batteries, batteries of different capacities, or
batteries of different types or brands.
•Do not attempt to recharge non-rechargeable batteries such as alkaline batteries.
•Do not load or use the batteries with the +/– polarity reversed. If the batteries do not fit smoothly in the battery
compartment, do not force them.
•Never use a battery if its outer coating (insulation) has been partially or entirely peeled off. Otherwise, leakage,
overheating or explosion may result.
•Some brand-new batteries may also have their outer coating (insulation) peeled off completely or partially.
Never use these batteries.
BATTERY PRECAUTIONS
Do not touch the electric contacts of the electronic flash to prevent malfunction.
To prevent overheating and deterioration of the light-emitting section, do not continue full activation more than 10
times in a row. After 10 successive operations, stop firing for a while until the light-emitting section cools down.
If you notice any abnormalities such as leakage, discoloration, deformation, overheating, or odor, stop using this de-
vice. Continued use could result in fire, overheating or explosion. Remove the batteries carefully to avoid burning
yourself and to prevent exposure to gas or dangerous fluids that may be released. For repair, contact Olympus.
Always remove the batteries when you don’t expect to use the electronic flash for a long period. Otherwise, heat
generation or fluid leak from the batteries may result in fire, injury and/or contamination of the surroundings.
Do not use a leaking battery. Doing so could result in fire or electric shock. Please contact your dealer or Olympus.
Do not handle the electronic flash with wet hands. Doing so could result in electric shock.
Do not leave the electronic flash in a place where it may be exposed to high temperatures. Otherwise, deterioration
of parts or fire may result.
Do not take out the batteries immediately after using the electronic flash continuously for a long period.
Otherwise, the hot batteries may cause burns.
Do not deform the battery compartment or allow any foreign objects to get inside.
CAUTIONHANDLING PRECAUTIONS
The electronic flash is composed of precision electronic parts. Absolutely avoid using or storing the electronic flash
in the following places, as this may result in malfunction or failure.
•Under direct sunlight, on a beach, etc.
•Anywhere exposed to high temperatures and humidity or rapid fluctuations in temperature and humidity.
•Any place exposed to excessive sand, dust or dirt. •Near a fire.
•Near an air conditioner or air humidifier. •Any place exposed to water or moisture.
•Any place subject to vibrations. •Inside an automobile.
Do not apply a strong vibration or shock to the electronic flash by dropping it or hitting it against something.
When the electronic flash has not been used for a long period, mold or moss may form. This can cause a
malfunction. To prevent this, it is recommended to check the operations before using the electronic flash after a
long period of storage.
Do not use the following kinds of batteries.
All rechargeable batteries must be recharged using the specified battery charger, simultaneously and completely.
Be sure to read the battery and battery charger instruction manual.
Outer coating (insu-
lation) is peeling or
has peeled off (even
if the battery is brand-
new).
The negative end is
slightly swollen and
is not covered by the
coating (insulation).
The negative end is
flat (whether or not a
part of the negative
pole is covered by
the coating).
