Usable batteries

Install two AA-type penlight batteries (1.5 V or lower) of any of these types: Alkaline-manganese (1.5 V), Lithium (1.5 V), Oxyride (1.5 V), Ni-MH [Nickel Metal Hydride (rechargeable), (1.2 V)]

• When replacing batteries, replace both with fresh ones of the same brand.
  • Carbon-zinc batteries are not recommended for use with the SB-400.
• Depending on battery specifications, when the Lithium batteries become hot, the safety circuits are activated, cutting off power. This often occurs when the flash unit is operated in the repeating flash mode. Battery power will recover when the temperature returns to normal.

Replacing/recharging the batteries

When the battery power becomes low, the Ready-light blinks at 2 Hz (twice in a second) for approx. 40 seconds. Replace or recharge batteries.

Standby function to conserve battery power

• If the SB-400 and the camera are not used for more than 40 seconds, the standby function activates and automatically turns the SB-400 off to conserve battery power (it goes into the standby mode).
• When the SB-400 is mounted on a camera, the SB-400 automatically turns off when the camera goes into standby mode after the camera's exposure meter is switched off.
• When in the standby mode, the SB-400 turns back on again when the [ON/OFF] switch is [ON], or the camera's shutter release button is lightly pressed.

Flash shooting distance range

The SB-400's usable flash shooting distance range is 0.6m to 20m (2 to 66 ft) and varies, depending on the camera's ISO sensitivity and lens aperture in use.

ISO sensitivity	Aperture
1600	4	5.6	8	11	16	22	32	—	—	—	—
800	2.8	4	5.6	8	11	16	22	32	—	—	—

Usable flash shooting distance range (m/ft)	1.9-20/6.2-65.0	1.4-14.8/4.6-49.0	1.0-10.5/3.3-34.0	0.7-7.4/2.3-24.3	0.6-5.2/2.0-17.0	0.6-3.7/2.0-12.1	0.6-2.6/2.0-8.5	0.6-1.8/2.0-5.9	0.6-1.3/2.0-4.3	0.6-0.9/2.0-2.3	0.6/2.0

Available flash modes

The SB-400's available flash modes vary, depending on the cameras and lenses in use or the camera's exposure mode.

• Each mode should be set on the camera body, since it cannot be set through the SB-400. For details, see your camera user's manual.
• For shooting with slow shutter speeds, use of a tripod is recommended.

Slow-sync flash

The flash is controlled at a slow shutter speed to obtain the correct exposure for both the main subject and background in low-light situations or at night.

Red-eye reduction

To prevent the center of your subject's eyes from appearing red in color pictures, the SB-400 fires three flashes at reduced output just before the picture is taken.

Red-eye reduction with slow-sync flash mode

In this mode, red-eye reduction is combined with slow-sync.

Rear-curtain sync

Rear-curtain flash sync creates a picture in which the blur or a moving subject appears behind the subject and not in front.

FV (Flash Value) Lock

Flash Value, or "FV", is the amount of flash exposure for the subject. Using FV Lock you can lock in the appropriate flash exposure for the main subject.

Exposure compensation and flash output level compensation

Exposure compensation allows you to take well-balanced pictures by intentionally modifying the flash exposure. This is useful when a subject of extremely high or low reflectivity is included in the scene or when you want to create flash photographs to match your creative preferences.

• Use the camera's exposure compensation function to modify both the SB-400's flash output level and the background exposure.
• With cameras that have the flash output level compensation function, the SB-400's flash output level can be adjusted to make exposure compensation for a flash illuminated main subject without affecting the background exposure.

Manual mode (only with D4, D800-Series, D700, D300-Series, D90, D7000, D5100, D5000, D3200, D3100, D60 and D40-Series cameras)

Manual flash operation is possible with the camera's custom setting.

Effective usage of Speedlight

With the SB-400 mounted on your camera's hot shoe, you can tilt the flash head in four steps (horizontal, 60°, 75° and 90°) to bounce the light off the ceiling.

Horizontal

Bounce flash

Shooting using the light bounced off the ceiling or other surfaces by tilting the flash head is called the bounce flash operation.

This technique offers following advantages:

• Eliminates Red Eye
• Creates soft shadows
• Prevents hair or clothes appearing to shine.

Notes on bounce flash

For a simple bounce flash technique, tilt the flash head upward and bounce the flash light off the ceiling. Note that the flash should not directly illuminate the subject.

White ceiling 60° 75° 90° 1-2m

• The recommended distance between the flash head and reflective surface (ex. ceiling) is 1 to 2m (3.3-6.6 ft).
• Note to prevent the flash light directly illuminating the subject.
• In color photography, select white or highly reflective surfaces to bounce the light off. Otherwise, your pictures will come out with an unnatural color cast similar to that of the reflecting surface.

Lightproof white paper

- When the distance between the flash head and reflective surfaces is long, use some A4-size white paper to bounce the light off. Check that the bounced light rightly illuminates the subject.

When the subject has a mottled appearance with the flash light, raise the tilting degree of the flash head.

Shooting with the flash head tilted up 90°

Depending on the lens' focal length and tilting degree of the flash head, the bounced light may illuminate the subject in a mottled tone.

- Tilt the flash head 90^ and take the shot.

In case the light is not enough

Shooting with higher ISO sensitivity

When the reflective surface is too far away, the light from Speedlight may be not enough to illuminate the subject.

• When taking photograph with digital cameras, set the ISO sensitivity higher than in normal shooting.
• For bounce flash shooting, set the lens' aperture larger (f/3.5, f/4.5 or f/5.6) than for normal shooting.
• Reduce the distance between the reflective surface and the Speedlight.

TTL Remote Cords SC-29/28/17 provide TTL auto flash operation when the SB-400 is used off-camera. Their flash shoes come with one tripod socket. The SC-29's AF-assist illuminator cannot be used with the SB-400.

Tips on Speedlight care

WARNING

Never use thinner, benzene, or other active agents for cleaning the Speedlight, as this may damage the Speedlight or cause it to catch fire. Using these agents may also impair your health.

Cleaning

• Use a blower brush to remove dirt and dust from the Speedlight and clean it with a soft, clean cloth. After using the Speedlight near saltwater, wipe the flash unit with a soft, clean cloth moistened slightly with tap water to remove the salt, then dry it with a dry cloth.
• Do not drop the Speedlight or knock it on a hard surface, as this may damage its precision mechanisms.

Storage

• Store the Speedlight in a cool, dry place to prevent malfunctions due to high humidity, as well as the growth of mold or mildew.
• Keep the Speedlight away from chemicals such as camphor or naphthalene. Avoid exposing the Speedlight to magnetic waves from televisions or radios.
• Do not use or leave the Speedlight in locations subject to high temperatures such as near a heater or stove, as this may cause damage.

• When not using the Speedlight for more than two weeks, be sure to remove the batteries to prevent damage due to battery leakage.

• Take the Speedlight out once a month, insert the batteries, and fire the unit several times to reform the capacitor.

• When the Speedlight is stored together with a desiccant, renew the desiccant occasionally.

Operating location

• An extreme temperature change can cause condensation to form inside the Speedlight. When exposing the Speedlight to high temperatures from very low temperatures, or vice versa, place it inside an airtight container such as a plastic bag. Leave it inside the container for a while before gradually exposing the Speedlight to the outside temperature.
• Avoid exposing the Speedlight to strong magnetic or radio waves from televisions or high voltage power transmission towers, as this may cause it to malfunction.

Notes on handling batteries

• Because flash consumes a large amount of battery power, rechargeable batteries may not operate properly before reaching the end of their stated lifespan or the number of charging/discharging as specified by the battery manufacturer.
• If the battery terminals become soiled, remove dirt and smudges before use, as this may cause a malfunction.
• Battery power tends to weaken as the temperature drops. It also gradually decreases when batteries are not used for a long time and recovers after a short break following intensive use. Be sure to check battery power and replace the batteries with fresh ones, if you notice any delays in the recycling time.
• Do not store batteries in locations subject to high temperatures and high humidity.

Ni-MH

Recycling rechargeable batteries

To protect the earth's environment, do not dispose of used rechargeable batteries yourself. Instead, take these batteries to your nearest recycling center.

Notes on continuous flash shooting

To prevent the SB-400 from overheating, allow the SB-400 to cool down for at least 10 minutes after the maximum number of continuous firings have been performed as shown in the table below.

CAUTION

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.

Max. number of continuous firings

Flash mode	Max. number of continuous firings
i-TTL auto flashManual flash (Flash output level: M1/1, M1/2)	15
Manual flash (Flash output level: M1/4 to M1/128)	40

CAUTION

Be careful when replacing batteries after continuous flash use, because batteries may generate heat during continuous flash photography.

Notes when using the SB-400 with D90, D80, D70-Series, D7000, D5100, D5000, D3200, D3100, D3000, D60, D50, D40-Series or COOLPIX 8800 cameras

When using the SB-400 with D90, D80, D70-Series, D7000, D5100, D5000, D3200, D3100, D3000, D60, D50, D40-Series or COOLPIX 8800 cameras, the SB-400 must be turned on.

• If the SB-400 is turned off while mounted on any of the above cameras, and the camera's "Auto flash" function is on, the camera's built-in flash will automatically pop up when shooting in poor light, coming into contact with the SB-400.
• It is recommended that the SB-400 be detached from the camera when flash is not required.

A note on microcomputer-controlled Speedlights

The Speedlight incorporates a microcomputer to control flash operations. In rare cases, the Speedlight may not work properly even after a fresh battery is properly installed. If this happens, replace the battery while the Speedlight's power is turned on.
