AA Alkaline/Rechargeable Ni-MH Batteries
The following describes the proper use of batteries and how to prolong their
life. Incorrect use can shorten battery life or cause leakage, overheating, fire,
or explosion.
■Cautions: Handling the Batteries
• Do not expose to water, flame, or heat, or store in warm or humid condi-
tions.
• Do not transport or store with metal objects such as necklaces or hairpins.
• Do not disassemble or modify the batteries or battery casing.
• Do not subject to strong physical shocks.
• Do not use batteries that are leaking, deformed, or discolored.
• Keep out of reach of infants and small children.
• Insert in the correct orientation.
• Do not mix old and new batteries, batteries with different charge levels, or
batteries of different types.
• If the fl a s h will not be used for an extended period, remove the batteries.
Note that flash settings will be reset.
• The batteries may be warm to the touch immediately after use. Turn the
fl a s h off and allow the batteries to cool before handling.
• Battery capacity tends to decrease at low temperatures. Keep spare bat-
teries in a pocket or other warm place and exchange as necessary. Cold
batteries may recover some of their charge when warmed.
• Fingerprints and other stains on the battery terminals can impair battery
performance. Thoroughly clean the terminals with a soft, dry cloth before
inserting them in the fl a s h .
If the batteries leak, clean the battery chamber thoroughly before
inserting new batteries.
If fluid from the battery comes into contact with skin or clothing,
flush the affected area with water. If fluid enters your eyes, immedi-
ately flush the affected area with water and seek medical attention. Do
not rub your eyes. Failure to observe this precaution could result in per-
manent visual impairment.
■Ni-MH Batteries
The capacity of Ni-MH batteries may be temporarily reduced when new, af-
ter long periods of disuse, or if they are repeatedly recharged before being
fully discharged. This is normal and does not indicate a malfunction.
The fl a s h draws a small amount of current even when off. Ni-MH batteries that
have been left in the fl a s h for an extended period may be drawn down to the
point that they no longer hold a charge. Battery performance may also drop
if the batteries are run down in a device such as a flashlight. Batteries that no
longer hold a charge even after repeatedly being discharged and recharged
have reached the end of their service life and must be replaced.
Ni-MH batteries can be recharged in a battery charger (sold separately). Bat-
teries may become warm to the touch after charging. Refer to the instructions
provided with the charger for more information. Use the charger with compat-
ible batteries only.
Ni-MH batteries gradually lose their charge when not in use.
■Disposal
Dispose of used batteries in accord with local regulations.

EN-3 ENGLISH
Liquid Crystal
In the event that the display is damaged, care should be taken to avoid con-
tact with liquid crystal. Take the urgent action indicated should any of the
following situations arise:
• If liquid crystal comes in contact with your skin, clean the area with a cloth
and then wash thoroughly with soap and running water.
• If liquid crystal enters your eyes, flush the affected eye with clean water for
at least 15 minutes and then seek medical assistance.
• If liquid crystal is swallowed, rinse your mouth thoroughly with water.
Drink large quantities of water and induce vomiting, then seek medical
assistance.
Caring for the Flash
To ensure continued enjoyment of the product, observe the following pre-
cautions.
■Storage and Use
If the flash will not be used for an extended period, remove batteries. Do not
store or use the flash in locations that are:
• exposed to rain, steam, or smoke
• very humid or extremely dusty
• exposed to direct sunlight or very high temperatures, such as in a closed
vehicle on a sunny day
• extremely cold
• subject to strong vibration
• exposed to strong magnetic fields, such as near a broadcasting antenna,
power line, radar emitter, motor, transformer, or magnet
• in contact with volatile chemicals such as pesticides
• next to rubber or vinyl products
■Water and Sand
Exposure to water and sand can also damage the flash and its internal cir-
cuitry and mechanisms. When using the flash at the beach or seaside, avoid
exposing the flash to water or sand. Do not place the flash on a wet surface.
■Condensation
Sudden increases in temperature, such as occur when entering a heated
building on a cold day, can cause condensation inside the flash. If this occurs,
turn the flash off and wait for the condensation to evaporate.
■Cleaning
Use a blower to remove dust from the flash window, then gently wipe with a
soft, dry cloth. Any remaining stains can be removed by wiping gently with
a piece of FUJIFILM lens-cleaning paper to which a small amount of lens-
cleaning fluid has been applied. Care should be taken to avoid scratching
the flash, particularly the flash window. The body of flash can be cleaned
with a soft, dry cloth.

Manual Flash Photography
Manual flash control is unaffected by reflections, making it the ideal
choice for pictures of highly reflective or unreflective subjects.
1
Turn the camera and flash on.
2
Choose from the (APS-C) or (35 mm) focal
length format displays.
3
Adjust exposure compensation. Choose higher values to increase
flash output, lower values to decrease.
4
Adjust zoom. Note that if is selected, the flash not light the
entire subject if zoom less than the focal length of the lens.
5
Adjust flash output by choosing a power ratio (PR) and confirm
that appears in the display.
6
Settings are complete when the red backlight turns off and the
icon for the selected setting stops blinking. Wait for the ready
lamp to light before taking photographs.
■Effective Range
The effective shooting range of the flash in meters can be calculated
by multiplying the guide number by the sensitivity (ISO) coefficient
and dividing by the aperture (for feet, multiply the result by 3.28).
Flash range = guide number × ISO coefficient ÷ aperture (f-number)
The guide number varies with flash output and lens focal length.

Using the Wide Panel
The wide panel is located above the flash window. When shooting
with wide-angle lenses with focal lengths as short as 20 mm (35 mm
format equivalent), extend the wide panel (if is selected for zoom,
you will also need to zoom the flash out to 24 mm). Flash output
drops slightly when the wide panel is used.
Wide

Bounce Lighting
Light from the EF-42 can be reflected (bounced) from a ceiling or wall
in TTL mode. Under some conditions, the flash may create dark shad-
ows in the background when aimed directly at the subject. A softer,
more natural effect can be produced by bouncing the light from the
flash off a ceiling or wall.
Rotate the flash head to choose the flash angle
and direction.
QDo not attempt to rotate the flash head beyond
the limits shown on the flash body. Failure to ob-
serve this precaution could damage the flash.
QFlash intensity may drop by about 25% depend-
ing on the color and type of the reflecting sur-
face.
QIf possible, bounce lighting off a surface that is
white or nearly white. Particular care is advised
when taking color photographs, as light reflected
from colored surfaces may affect the colors in the
image.

EN-12
ENGLISH
Continuous Use
Using the flash many times in quick succession can cause overheating
that may damage the flash. It is recommended that you turn off the
flash for ten minutes after about ten consecutive shots.
