CHILDREN MAY SWALLOW BATTERIES.

Keep batteries out of the reach of children. If a child swallows a battery, contact a doctor immediately.

Do not point the flash at a driver or rider of a vehicle (bicycle, automobile, train, etc.) and fire the flash. This may cause a traffic accident. Turn off the flash or make sure the flash does not fire before shooting this kind of subject.

Do not fire the flash close to the eyes of a human or animal. Eyesight may be temporarily impaired.

If an internal component is exposed because the unit was dropped or otherwise damaged: ① Never touch the exposed component.

②Immediately remove the batteries, being careful not to expose yourself to electric shock, burn yourself, or otherwise injure yourself,

③Send the unit to your camera store or Olympus service center. The unit contains a high-voltage circuit that could cause electric shock, burn you, or otherwise injure you.

Do not try to disassemble, repair, or modify the unit. The unit contains a high-voltage circuit that may cause electric shock, burn you, or otherwise injure you.

Do not activate the flash when your skin or other object is in contact with the flash reflector. Do not touch the flash reflector after the flash has fired repeatedly. You may burn yourself.

Do not use the unit near flammable gas or substances (such as gasoline, benzine, or thinner). This can cause explosion or fire.

If the unit is dropped in water, or if water, metal particulate, a flammable foreign object gets into the unit:

①Remove the batteries immediately.

②Send the unit to your camera store or Olympus service center. Using the unit in this condition may cause fire or electric shock.

Do not wet the unit or touch the unit with wet hands. This could cause electric shock.

Batteries

Insert two “AA”-size alkaline batteries, lithium batteries, nickel-manganese batteries, NiMH batteries or NiCd batteries as shown in the illustration.

If the camera is equipped with a hot shoe, mount the flash directly on the hot shoe.

If the camera is equipped with an external flash terminal, mount the flash using the flash bracket and bracket cable.

You cannot use the FL-20 flash if the camera is not equipped with a hot shoe or external flash terminal.

Slide the flash all the way into the hot shoe.

Turn the shoe lock dial to secure the flash in place.

The wide panel covers an angle equivalent to a 24 mm wide-angle lens assuming the use of a 35 mm film.

Note that “AA”-size manganese (zinc-carbon) batteries cannot be used.

Set the Mode dial to AUTO.

When the CHARGE lamp lights up, press the TEST button and confirm flashing.

Indicator Lamps The following lamps indicate the flash status.

CHARGE lamp		OFF	ON	Regular blinking	Communication errors
					When the FL-20 mode is; TTL AUTO: Error communicating with the camera.
	OFF	Under charge	Charge completed	Communication error
AUTO CHECK					(The camera is OFF, set to the wrong mode, etc.)
lamp	Blinking	Optimum light intensity	–	Low battery warning	The CHARGE lamp blinks when the camera’s LCD monitor is turned off on the following models
					(as of January, 2003): C-4000ZOOM, C-4040ZOOM, C-3000ZOOM, C-3040ZOOM, C-2040ZOOM.

TTL AUTO Operation <Flash must be connected to the camera through a hot shoe or 5-pin external flash terminal>

The AUTO CHECK lamp will blink when the flash illumination reaches optimum intensity. If the

AUTO CHECK lamp does not blink, move closer to the subject or reduce the camera’s aperture.

The AUTO CHECK lamp does not blink on the following models (as of January, 2003):

C-4000ZOOM, C-4040ZOOM, C-3000ZOOM, C-3040ZOOM, C-2040ZOOM

AUTO Operation

Camera’s ISO speeds and apertures

ISO speed	Aperture

MANUAL Operation

The flash emits light at the maximum intensity. The AUTO CHECK lamp does not blink in this mode.

Optimum shooting ranges

Set the FL-20’s Mode dial to TTL AUTO and set the

camera’s MODE DIAL to or .

In the TTL AUTO mode, the flash adjusts the light intensity automatically according to changes in the camera’s aperture. (TTL AUTO mode operation requires that the camera’s mode is set as shown in the above illustration.)
