For your safety
CAUTIONS for Speedlights
A 1. Do not touch the flash unit with wet hands, as this could cause an
electric shock.
2. Keep the flash unit away from children to prevent them from putting
the unit in or near their mouth, or otherwise touching a dangerous part
of the product; as such contact could cause an electric shock.
3. Do not apply strong physical shocks to the unit, as this could cause a
malfunction that could cause the unit to explode or catch on fire.
4. Never use active agents that contain flammable substances such as
paint thinner, benzene or paint remover to clean the unit, and never
store the unit in locations containing chemicals such as camphor and
naphthalene, as this could damage the plastic case, cause a fire or cause an
electric shock.
5. Remove any batteries from the unit before storing the unit for a long
time to prevent the unit from catching on fire or leaking corrosive liquids.
6. Do not exceed the maximum number of continuous firings, as this may
cause the flash head to overheat and can result in burns and damage to the
flash panel and body.
WARNINGS for Batteries
1. Never heat or throw batteries into a fire, as this could cause the batteries
to leak corrosive liquids, generate heat or explode.
2. Do not short-circuit or disassemble the batteries because this could cause
the batteries to leak corrosive liquids, generate heat or explode.
3. Do not mix battery types, brands or old and new batteries, as this could
cause the batteries to leak corrosive liquids, generate heat or explode.
4. Do not install batteries in the reverse direction as this could cause
the batteries to leak corrosive liquids, generate heat or explode. Even if
only one battery is installed in reverse it will cause the Speedlight
to malfunction.
5. Be sure to use the battery charger specified by the battery maker to
avoid the possibility of batteries leaking corrosive liquids, generating heat or
exploding.
6. Do not carry or store batteries along with metallic materials such as
necklaces and hair pins because such materials could cause the batteries to
short-circuit, leading to battery leakage, heat generation or an explosion.
In addition, specially when carrying a quantity of batteries, place them
carefully in a storage case that prevents the battery terminals from
touching another battery's terminals because if they touch in reverse order
it could also cause the batteries to short-circuit, leading to battery leakage, heat
generation or an explosion.
