Fantasea Nano Flash Instruction Manual 26110120

1. Introduction

The Nano Flash is a universal underwater slave flash especially designed for compact digital

housings. It triggers in sync with the camera built-in flash and was designed to significantly

improve the colors in underwater photographs, as well as to retrieve the light absorbed by

water. The Nano Flash is recommended at all depths, during daylight and night dives. It also

enhances images by allowing for diverse creative lighting opportunities, while reducing the

amount of backscatter in the images and preventing the shadowing effect caused by the

camera internal flash, especially when accessory lenses are mounted on the housing lens

port.

iii.Insert the Nano Flash carefully into the front door of the housing, making

sure it seats fully.

iv.Prior to closing the Nano Flash Housing, the O-ring, positioned at the back

door, should be visually inspected. If there is any debris present, including

dirt, sand, dust, hair, grease or other matter, it must be cleaned to ensure a

proper watertight seal. Cleaning the O-ring is a simple matter of wiping it

with a damp, soft cloth to remove the foreign matter. Be careful the cloth

you use does not leave any of its own material behind, as this can also affect

the effectiveness of the seal.

v. It is recommended to apply a slight layer of silicone on the O-ring. Use the O-

ring Remover in order to remove the O-ring from its groove and make sure it

note that the amount of lubrication required on the O-ring is only enough to

allow it to slip into place without friction, so it does not twist or become

dislodged. More grease is not necessarily better, and in some cases might

interfere with the watertight seal of the Nano Flash Housing.

vi.When replacing the O-ring seal, place it back into the same groove you have

taken it out of. Be sure it is completely positioned in the channel for a proper

seal.

vii. Close the back door of the housing. Make sure you close it completely.

viii. Rotate the Dial Lock counterclockwise until

the Security Lock is pointed upwards. Lock

the Dial Lock by pushing the Security Lock in

(image #3).

e. Select the Proper Pre-Flash Program for Your

Camera

i. Please note that watching the Nano Flash

fire does not mean it triggers on the right

timing. If it is not synchronized with your

camera, this will usually result with

underexposed images.

What are Pre-Flashes?

Pre-flashes are one or more flashes given out to assist in the focusing and

exposure setting of the camera before the actual picture-taking primary flash

is fired. It is important to set the Nano Flash to the correct pre-flash setting so

it fires in sync with the primary flash of the camera.

The Nano Flash features 3 different pre-flash settings (image #4):

1 For cameras with no pre-flash

2 For cameras with 1 pre-flash

3 For cameras with 2 pre-flashes

ii.In order to properly synchronize the Nano Flash with your camera, you should

determine which pre-flash program on the Nano Flash is the most suitable

with your camera internal flash. In order to do so, please follow the

instructions below:

1. Place your digital camera in front of the Nano Flash within a distance of

approximately 1 meter, so they are facing each other.

2. Set your camera built-in flash to ON.

3. Turn the Nano Flash on by setting the Pre-

f. Test the Watertight Seal of the Nano Flash

After closing the Nano Flash, always test it in a shallow water pool prior to diving

with it, in order to verify that it is perfectly watertight sealed. Make sure no

bubbles escape from it and that no water enters the housing.

g. Mount the Nano Flash on an Arm

i. Remove the screw from the Y-S Connector at the bottom of the Nano Flash

Housing by unscrewing it all the way out.

ii.Position the Nano Flash on top of the arm so that the Y-S Mount on top of the

arm is aligned with the Y-S Connector at the bottom of the Nano Flash (image

#5).

iii.Install the screw all the way through the Nano Flash and arm. Tighten it

enough to keep the Nano Flash within a fixed position (image #6).

h. Attaching a Nano Fiber Optic Cable to the Nano Flash (optional)

Although the Nano Flash features a slave sensor and is capable of synchronizing

with the camera internal flash without using any cables in most diving conditions,

a fiber optic cable ensures the best synchronization between the camera internal

flash and the Nano Flash at all angles and within various diving conditions,

especially when photographing in shallow clear water with bright ambient light.

i. The fiber optic cable consists of

two ends: One is attached to a

white plastic fitting (flat white

plastic at the end of the cable

with Allen screw inside), and

the other is loose (image #7).

Insert the exposed end of the

fiber optic cable (the end

without the fitting) into the

small hole of the black Nano Adaptor unit, starting from the end that features

a screw and pushing it towards the end that features an O-ring, until the fiber

optic cable reaches the end of the adaptor.

ii.Use the tool included in the Nano Adaptor Kit in order to tighten the screw

on the adaptor (image #8 on the following page). Tighten it enough to

Image #5

Image #6

Image #7



Fantasea Nano Flash Instruction Manual 26110120

stabilize the fiber optic cable inside the adaptor, but don't tighten it too

strongly. Tightening the screw too much might damage the fiber optic cable.

iii.Install the black and clear plastic diffuser cover on the Nano Flash Housing.

iv.Insert the Nano Adaptor inside the lower right grommet (the one with the

wider hole) of the black diffuser cover, so that the adaptor screw doesn't get

in its way. Insert it all the way to the end, and do not use force once you

encounter any resistance (image #9).

v. If attaching the Fiber Optic Cable to

a Fantasea FP7000 Housing or any

other housing that features a

dedicated fiber optic cable

attachment configuration (image

#10), please refer the housing

instruction manual for specific

instructions regarding attaching the

fiber optic cable to the camera housing. If attaching the Fiber Optic Cable to

any other standard camera housing, please follow the instructions below.

vi.The other end of the fiber optic cable attaches outside of the camera housing

- opposite the camera internal flash - by using both sides of the Velcro strip

included in the kit. The white plastic fitting normally comes with the Velcro

tape attached and therefore you are only required to apply the other side of

the Velcro strip on the housing to receive it (images #11 and #12 on the

following page). If your housing features a built-in flash diffuser, the Velcro

strip should be attached beneath it, directly to the housing. If possible, place

the Velcro strip between the built in flash diffuser and the housing,

positioned opposite the internal flash of the camera.

vii. It is preferable to totally block out the internal flash of the camera after

attaching the camera side of the cable by applying black electrical tape over

the fiber optic connector attached to the housing case. This effectively

achieves two things: it diminishes the effects of backscatter, as well as

eliminates any shadowing effect caused by lens accessories mounted on the

housing lens port. Removing the built-in flash diffuser will have no affect on

lighting.

viii. In some cases, after using the fiber optic cable frequently or for a long period,

you might encounter a decrease in performance. You can easily solve this

problem by cutting 1 cm/0.3 inch off the fiber optic cable ends, using a sharp

tool and performing a very straight angled cut. This allows you to remove any

worn ends and to expose a new portion of the cable.

i. Taking Photographs with the Nano Flash

i. Turn the Nano Flash on by setting the Pre-Flash Mode Dial to the pre-flash

program found most compatible with your camera (section e).

ii.Position the flash in a way that it is pointed at your subject. Also, if a fiber

slave sensor, so the Nano Flash can synchronize with your camera internal

flash.

iii.Set your camera built-

iv.Take a photograph by pushing the shutter-release button of the camera. The

camera built-in flash fires and triggers the Nano Flash as well. Always take

photographs with the Ready Light fully lit up.

v. Adjust the output of the Nano Flash by turning the Power Output Control to

achieve the desired exposure in your photograph.

vi.Removable Flash Diffusers: It is highly recommended to install a diffuser

when shooting wide angle or extreme macro images. In wide angle

photography, the diffuser can be used in order to spread the light more evenly

and in a way that it covers a greater angle. In macro photography, the diffuser

Image #12





Fantasea Nano Flash Instruction Manual 26110120

can be used to absorb part of the light when

the flash is too powerful, even when set to the

lowest output. In order to install any of the

flash diffusers, first install the Diffuser Holder

on the flash housing by simply clicking it in.

Then slide any of the diffusers through the slot

found at the top of the Diffuser Holder (image

#13). It is recommended to secure both the

Diffuser Holder and the flash diffusers to the

flash by secure strings.

vii. When the Nano Flash is not in use, it is best to

turn it off in order to prevent exhaustion of the

batteries.

j. Care & Maintenance

The Nano Flash requires only a minimum amount of care for reliable

performance. The following tips will enable you to get the best results.

i. Submerge the flash in fresh water for about 20 minutes after every dive in

order to dissolve the salt water crystals from around the controls and

openings of the flash. Manipulate each of the movable controls to assist the

removal of salt particles from these tight areas.

ii.Allow the flash to dry thoroughly before packing it away for the day or for

the trip home. You may use a soft towel or cloth to dry the flash. Be sure

there is no grease or other debris on the towel.

iii.Visually check the condition of the O-ring before every dive. If it is dirty,

clean it with fresh water and dry it with a soft cloth as described above. If it

is damaged in any way, such as cut or perforated, replace it immediately.

iv.It is recommended to slightly lubricate the O-ring periodically. It's important

to note that the amount of lubrication required on the O-ring is only enough

to allow it to slip into place without friction, so it does not twist or become

dislodged. More grease is not necessarily better, and in some cases might

interfere with the watertight seal of the flash.

v. Do not drop the flash on hard surfaces. It is not a shock absorber, and could

crack, affecting its watertight integrity. It could also cause damage to the

electronic components inside.

vi.When travelling, remove batteries, leave back the door loose or

unassembled and pack the unit in a protected fashion in a padded case or

bag.

vii. Never dive with the Nano Flash to a depth greater than 60 meters/200 feet.

viii. Never store the flash or housing in high temperatures (above 60C/140F

degrees).
