■This electronic flash has been designed exclusively for use with Olympus digital cameras. Do not connect the electronic
flash to a camera not manufactured by Olympus, as this may result in a malfunction or damage to the camera and/or
flash.
DANGER
■The electronic flash incorporates high-voltage circuitry. Never attempt to disassemble or modify it, as this may
result in electric shock and/or injury.
■Do not use the electronic flash in a place where it may be exposed to flammable or explosive gas. Otherwise,
fire ignition or explosion may result.
■To prevent a traffic accident, do not direct the flash towards the driver of a car.
WARNING
■Do not fire the flash or AF illuminator light immediately in front of a person’s eyes (particularly an infant).
Exposure to the light from the flash at a very short range may cause irreparable injury to the eyes. Be espe-
cially careful to avoid using the electronic flash at a distance of less than 1 meter from an infant.
■Do not leave the electronic flash and batteries within reach of children.
•If a child swallows a battery or small accessory, see a doctor immediately.
•If the flash is emitted near a child, their eyes may be injured irreparably.
•Moving parts of the electronic flash could injure a child.
■
Avoid the following actions to prevent fire or injury due to battery fluid leak, overheating, fire ignition or bursting.
•Do not use batteries that are not specified for use with this electronic flash.
•Do not throw the battery in a fire, expose it to heat, short-circuit it, or disassemble it.
•Do not mix old and new batteries, or batteries of different types or brands.
•Do not attempt to recharge non-rechargeable batteries such as alkaline batteries.
•Do not load batteries with the +/– polarity reversed.
■Do not store the electronic flash in a place exposed to excessive dust or moisture. Otherwise, fire or electric
shock may result.
■Do not use the flash when it is covered by a flammable object such as a handkerchief.
Do not touch the light-emitting area after use. It will be very hot and could burn you.
CAUTION
■
If you notice any abnormalities such as leakage, discoloration, deformation, overheating, or odor, stop using this
device. Continued use could result in fire, overheating or explosion. Remove the batteries carefully to avoid burn-
ing 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, deterio-
ration 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.
HANDLING 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 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.
BATTERY PRECAUTIONS
■Use only the specified batteries.
•AA (R6) alkaline dry cell batteries (LR6 type).................... x 4
•AA (R6) Ni-Cd batteries ..................................................... x 4
•AA (R6) Ni-Mh batteries..................................................... x 4
•AA (R6) Ni-Mn batteries (ZR6 type)...................................x 4
•AA (R6) lithium batteries (FR6 type).................................. x 4
•Lithium battery packs (CR-V3 type) (Olympus LB-01)....... x 2
• AA (R6) manganese batteries cannot be used.
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.
