INTR DUCTI N
Thank you for purchasing an kelite Strobe. kelite brings over 45 years of underwater
photographic and lighting experience to the strobe market. kelite Strobes are designed
and built in the USA by kelite to suit both the professional and the amateur photographer.
DS51 Strobe USE
The purpose of a strobe is to illuminate the subject and assist the camera in taking vivid
pictures. The kelite DS51 strobe is equally suited for general and wide-angle
photography, covering up to 80° with a diffuser. The compact size of the DS51 makes it
ideal for macro photography while its 5700°K color temperature helps bring out the true
colors of the underwater world.
The kelite DS51 strobe is pre-flash compatible and operates with traditional film
cameras, DSLR cameras, and digital still cameras. TTL/auto and manual exposure with
five fractional power setting firing modes are featured. The DS51 electronics are safely
sealed away from the battery compartment.
Aim the DS51 strobe and illuminate your subject’s colors with the optional Mini-C Lite and
Lite Bracket 4073 (page 5). The bracket secures beneath the strobe, allowing the Mini-C
Lite to be used as both an aiming light and as a night diving light.
VERVIEW F DS51 FEATURES
- Mode switch features TTL/auto and manual exposure settings.
- Battery compartment accommodates four AA batteries: alkaline, NiCad, or NiMH.
Lithium-ion batteries are NOT recommended.
- Ready light indicates when strobe has recycled.
- Female kelite bulkhead connector accepts different camera sync cords and the
4403 Optical Slave Converter.
- Exposure guide label references recommended exposure settings.
- Diffuser provides softer lighting, wider coverage angle and reduces strobe output
by one f-stop.
STARTING UT
Before using the kelite DS51 Strobe, please read this owner’s manual thoroughly and
retain it for future reference. kelite recommends becoming familiar with the features and
functions of the kelite DS51 Strobe above water before trying the camera and strobe in
the water. And, if you have not yet done so, it is suggested that you read your camera’s
owner’s manual as well.

IKELITE ARM/M UNTING SYSTEMS
kelite offers several arm choices compatible
with the DS51. Arms and mounts are NOT
supplied with the strobe unless purchased as
part of a complete package.
The DS51 will accept several kelite strobe
arms and mounts on the underside of the
strobe body. For further information, please
visit www.ikelite.com.
Caution: kelite arm systems are designed for
underwater use. Be careful when transporting
the system above water since some camera
trays, or arm adjustments may be unable to
support the weight of the strobe(s) above
water.
M UNTING THE STR BE
Lite Bracket 4073
The optional Lite Bracket secures the
kelite Mini-C Lite underneath the
DS51 strobe for use as an aiming light
and night diving light.
The Lite Bracket is placed between
the strobe body and the strobe mount.
Using a Phillips Head screwdriver,
remove the strobe mount from the
underside of the strobe and secure the
Lite Bracket in its place. Then, using

The female kelite bulkhead connector permits kelite sync cords to be connected to the
strobe. The sync cord relays a signal from the camera to the strobe that tells the DS51 when
to flash.
The removable waterproof bulkhead cap seals the bulkhead connector when a cord is
connected to the DS51. The strobe’s bulkhead connector must be sealed to remain
waterproof (page 7).
Caution:
- Do not leave the sync cord connected to the camera housing or strobe
for prolonged periods as electrolysis could occur and make removal of the
equipment impossible.
- Do not disconnect the sync cord from the camera housing or strobe when
underwater, or when wet. These items are not waterproof when disconnected.
C NNECTI N T STR BE
To connect a sync cord to the DS51 Strobe, follow these instructions:
1. Turn the strobe to OFF and make sure all components are dry. Clean and
lightly lubricate the stem o-ring and the bulkhead connector threads.
Check the o-ring for nicks or cuts.
2. Note the positioning of the receptacles and pins on the end of the cord. Properly
align the end of the cord and insert it into the strobe bulkhead connector.
When using the 4103.51 cord, which connects an kelite housing to an kelite
strobe, both cord ends are identical; either end can be connected to the
strobe.
3. The connector threads are very fine; do not cross thread. f it is difficult
to turn the knurled retaining ring on the cord or sensor, you are cross-threading.
This can make removal of the strobe impossible.
Hand-tighten the knurled retaining ring on the cord. Push the end of
the cord further into the bulkhead connector and continue to tighten the knurled
retaining ring. Do not use a tool when tightening. t could damage the
cord or strobe.

kelite Sync Cord
TTL SYNC C RDS
kelite offers interchangeable sync cords so that the DS51 strobe can be connected to
different camera systems. A TTL sync cord (illustrated above) is required to send the
TTL/auto exposure signal from the camera to the strobe.

8
For use with the following types of systems:
- kelite housings for digital cameras with TTL conversion circuitry
- kelite housings for film cameras
- Nikonos V, RS cameras
- Non- kelite housings for digital cameras and compatible TTL adapter
Connect the strobe using an appropriate kelite TTL sync cord. Digital cameras require the
use of a Digital TTL sync cord. These cords are designated by a blue band at one end.
The DS51 may be used in TTL/auto or manual exposure modes.
TTL (thru-the-lens) exposure automatically compensates for aperture, distance and filters.
When the strobe fires, the camera reads the light and signals the strobe to turn off when
the exposure is correct.
Strobe output can be adjusted in TTL/auto mode using either exposure compensation built
into the camera or an exposure compensation control (dial or push buttons) located on the
back of the housing (if applicable).
f an exposure compensation control is featured in the back of the housing, strobe output
may be controlled manually while the strobe itself is left in TTL/auto mode. n order to use
the manual exposure modes on the strobe itself, the housing electronics must be set to a
manual position.
When using a non- kelite TTL adapter or third party conversion circuitry, please refer to
the product instructions for help in using the DS51 with this setup.

Trigger your kelite DS-series strobe off any camera or strobe flash. The Optional 4403
Optical Slave Converter simply attaches to the strobe's electrical bulkhead in place of a
sync cord connector. The enlarged slave window provides approximately a 90 degree
field of view for remote triggering; or you can thread on the Fiber Optic Port (included
with Slave Converter) for the attachment of and triggering with a fiber optic cord.
The Optical Slave Converter automatically configures itself for compatibility with both
pre-flash and non pre-flash camera modes. No setting of small switches or confusion
over number of pre-flashes. Simply turn on your strobe and take one picture to configure.
The Optical Slave Converter can be extended using an optional 3-foot Extension Cord
for creative backlighting in wrecks, caves, and pool studio set-ups. t can also be used
above water for studio photography work.
The Optical Slave Converter supports manual exposure modes as set on the attached
DS strobe. TTL exposure mode is not supported.
Use of multiple strobes requires one Optical Slave Converter per strobe.
The Converter can be triggered off a camera flash or another strobe.

PENING THE C MPARTMENT
Always turn the strobe to OFF before opening the battery door located at the back of the
strobe.
To access the battery compartment, rotate the knob counter-clockwise several times and
gently pull the door off. Tilt the rear portion of the strobe down while removing
the battery door to eliminate the possibility of water droplets falling into the battery
compartment after a dive. Do not remove the knob from the battery door.
The battery compartment is sealed separately from the main electronics. Do not
disassemble the strobe. Disassembly will void your kelite limited warranty.
BATTERY C MPARTMENT -RING
Be aware of the position of the o-ring around the perimeter of the battery door. Keep the
o-ring and sealing surfaces clean.
Lubricant is not necessary for proper sealing of the battery door o-ring. To extend its life,
you can lightly lubricate the exposed part of the door’s o-ring before storing
(see “Cleaning and Storage”, page 18).
CHANGING THE BATTERIES
nstall four AA-cell batteries: alkaline, NiCad, or NiMH. Refer to the “+” and “ – “ markings
in the battery compartment to help properly install the batteries. f the batteries are
installed incorrectly, it may damage the strobe’s electronics.
Always carry spare batteries; weak batteries cause many camera and strobe problems.
t’s time to replace the batteries when the ready light remains dark for 15 seconds or
longer after a flash (see “Strobe Ready Light”, page 10).
Note: t is possible to buy bad “new” batteries, so check the voltage output with
a meter. Lithium-ion batteries are not recommended due to their effect on the strobe’s
recycle time and the batteries’ thermal switch characteristics.

C MPARTMENT FL DING
The battery compartment is separate from the DS51 factory sealed electronics. Should
the battery compartment flood, flush the compartment with fresh water and dry
thoroughly. Determine the cause of the flooding to the best of your ability. Send the
DS51 and other system components involved to kelite for inspection and testing as
soon as possible.
Often, divers find themselves in remote locations for extended periods without access to
multiple strobes. f the strobe with the flooded battery compartment is the only one
available to you at the time and you’re desperate to continue shooting, please follow
these instructions for a temporary fix:
1. Air out and thoroughly dry the battery compartment with air from a blow dryer
or a SCUBA tank hose.
2. Wash out the battery compartment with alcohol. Repeat Step 1.
3. Replace all batteries after battery compartment flooding. Never re-use
batteries that have been wet. The water could create an internal short circuit
in the strobe at some later date, potentially causing an explosion.
4. Reassemble with fresh batteries.
5. After returning from your trip, send the DS51 and other system components to
kelite for inspection and testing.
CL SING THE C MPARTMENT
Again, check that the o-ring and sealing surfaces are clean. Make sure the o-ring is back
in its original position and free of any debris.
Lubricating the o-ring will NOT result in a better “seal” to the strobe and is not
recommended. The o-ring is seated in the battery door channel and does not need to
be removed. Frequent removal of the o-ring can increase the risk of dirt or debris getting
into the o-ring channel and causing a leak. f the o-ring needs to be removed, do not use
a screwdriver or other sharp instrument that may damage the o-ring channel and result
in a leak.
Replace the battery door. Make sure the door fits into the recess around the battery
compartment. Rotate the knob clockwise several times and firmly hand-tighten to assure
the proper o-ring seal; otherwise, the battery compartment may leak. The o-ring seal is
visible through the battery door. Visually confirm that there is a solid black line
which indicates a seal all the way around the door.
BATTERY C MPARTMENT continued

S T R B E DIFFUSER
USING THE DIFFUSER
The white diffuser can be secured to the front of the DS51 strobe when softer lighting
or a coverage angle of up to 80° is desired.
The diffuser reduces the DS51 light intensity by one full f-stop.
For the TTL/auto mode example with an SO rating of 100, if you set your camera to f-8
without the diffuser, you can shoot subjects up to 1.2m (4’) away. f you add the diffuser to
the strobe with the camera set at f-8 and using SO 100, you must reference one number
greater than f-8 in the chart. n this case, that number is f-11, which means you can shoot
subjects up to 0.6m (2’) away.
DIFFUSER INSTALLATI N AND REM VAL
1. The white diffuser features two protruding tabs for use in installation and
removal. The tabs on the diffuser should be positioned away from the strobe.
2. Place the diffuser over the front of the strobe. Spread the two tabs apart, insert
the diffuser into the recessed front, and then rotate the diffuser until it locks
into position.
3. To remove the diffuser, bend one tab out towards the edge while lifting
simultaneously.
A lanyard or string can be attached to the diffuser by threading it through the
two circular openings near its edge. Attach the other end to the strobe arm to
prevent accidental loss.

STR BE READY LIGHT
The kelite DS51 Strobe features a ready light at the rear of the strobe that glows red
when the DS51 has recycled and is ready to fire its flash again. This recycling time should
not exceed 15 seconds. f the glow disappears for longer than 15 seconds between
flashes, it may be time for new batteries (see “Changing the Batteries” on page 11).
STR BE READY LIGHT AND TTL H USING
When the DS51 is in TTL mode and connected to an kelite DSLR housing, the strobe
ready light will glow green for approximately two seconds to indicate a correct exposure. f
no green light appears, check the image for possible underexposure. When the strobe has
recycled again, the ready light will again glow red indicating that the strobe is fully
powered and ready to fire. f the strobe ready light does not glow red, the batteries may
be expended.
Your camera’s ready light “lightning bolt” in the camera viewfinder may blink while the
DS51 is recycling and then glow solid when the DS51 is fully charged. Nikon DSLRs and
older Canon DSLR models such as the 20D and Rebel XT will always display a solid glow
“lightning bolt” regardless of the strobe cycle.
READY LIGHT and 4403 ptical Slave Converter
When using the DS51 strobe with the optional Optical Slave Converter (page 10), without
optional sync cord, the strobe is not electronically connected to the camera. Therefore, the
ready light in the viewfinder of the camera indicates when the on-camera flash has
recycled. Examine both the camera and strobe ready lights to make sure both flashes
have fully recycled before taking the next picture. The Converter can be triggered off a
camera flash or another strobe.

M DE SWITCH
The DS51 Strobe mode switch has eight different positions: OFF, TTL/auto exposure
setting, and six manual exposure settings. Refer to illustrations on page 16.
FF P SITI N (Refer to illustrations on page 16)
(Fig.1) Shows the mode switch in the OFF position. The white indicator on the knob
aligns with OFF. Always turn the strobe to OFF before connecting or disconnecting a sync
cord or opening the battery compartment.
TTL/AUT EXP SURE P SITI N (Refer to illustrations on page 16)
(Fig.2) Shows the mode switch in the TTL (Thru-the-Lens) / auto exposure position. From
the OFF position, rotate the switch clockwise to access the TTL/auto exposure setting; the
white indicator on the knob aligns with TTL. When taking pictures with the mode switch in
this position, the camera automatically signals the strobe to turn off
when the exposure is correct.
- When the DS51 is connected directly to the camera, the camera must feature
compatible TTL/auto exposure to utilize this mode.
- The TTL/auto firing mode must be selected when connecting the EV Manual
Controller #4100.6 (page 10).
MANUAL EXP SURE P SITI N (Refer to illustrations on page 16)
Figure 3 shows the mode switch in the manual exposure mode with the DS51 Strobe
turned to the F (full power) position. Rotate the mode switch clockwise to access the
different power settings. Each power setting clockwise from F reduces the light output of
the DS51 Strobe in one-half f-stop increments. When shooting in the manual mode, it is
suggested that you start the strobe at full power and adjust the camera’s aperture based
on the strobe-to-subject distance.
f the subject in the photo is underexposed (dark) you must move closer to the subject. f
the subject is overexposed (light), then you can rotate the mode switch clockwise to
reduce the light output of the strobe until the desired exposure is obtained. The DS51
provides five reductions in power in one-half f-stop increments from the full power setting.
(Fig.4), for example, shows the mode switch set to -1 and 1/2 f-stops.
Do not use manual strobe settings with a camera that emits “pre-flash.” Leave the
DS51 in the TTL position and adjust exposure using your camera settings or
housing conversion circuitry (if applicable).

VISUAL INSPECTI NS
Visual inspections are important. Take the time to examine the entire assembled setup
(strobe, camera housing, arms, etc.) above water. An improper seal or loose
connection can cause a lot of damage. Always check for leaks once you place the
equipment in the water.
INSURANCE
t is recommended that you add an all-risk floater to your homeowner’s and/or renter’s
insurance policy to cover your equipment against loss or damage. While the kelite DS51
Strobe has a limited warranty against manufacturing defects, it does
not cover customer neglect.
TIPS
- Photograph through as little water as possible; move in close. Maximum
recommended shooting distance underwater is 1.8m (6’).
- Use the diffuser for softer lighting or a coverage angle between 70° and 80°.
- f possible, measure the light with a meter and set the camera aperture
between your subject and the background, meter the available light and set
the camera aperture accordingly. Using a narrower aperture darkens the
background.
A wider aperture lightens the background and may overexpose the photographs.
- More natural looking photos can be achieved through the addition of a second
external strobe. The kelite 4403 Optical Slave Converter works well with a
second strobe when you plan on using manual exposure.
- Always carry spare batteries. Weak batteries are the cause of many strobe and
camera problems; check the voltage with a meter. Note: it’s possible to buy bad
“new” batteries.
- Do not fire the strobe more than 15 times in rapid succession. f this does
happen, allow the DS51 to cool off for at least 10 minutes before resuming
photography.
LUBRICANT
- Use only kelite brand silicone lubricant with kelite brand o-rings; other brand
lubricants can cause the kelite o-rings to swell in size.
- Do not use spray lubricant; it can crack the plastic parts of the strobe.
- kelite brand silicone lubricant is provided for the sync cord stem o-ring and the
bulkhead connector threads. Use only enough lubricant to lightly cover the area
being applied; wipe off any excess with a clean cloth.
- Lubricant only reduces friction; it is not a sealant.
REC MMENDATI NS

18
Your kelite DS51 Strobe should be given the same care and attention as your
other photographic equipment. After using your strobe in water, please follow
these instructions to insure the DS51 longevity and good working order.
CLEANING AND ST RAGE
Caution: Make sure the DS51 battery door is on and tightened down before
exposing the strobe to water. deally, water should never enter the battery
compartment. f this does occur, see “Compartment Flooding” on page 12.
1. Always rinse the exterior of the DS51 with fresh water after use, especially after
exposure to salt water. While rinsing, turn the mode switch to free salt or debris
that might have accumulated in the DS51 recesses during the dive.
2. Dry the DS51 thoroughly.
3. Check the battery door’s o-ring and sealing surfaces for any debris and gently
wipe it away with a soft, lint free cloth. Lightly lubricate the exposed part of the
door’s o-ring. Lubricant will help preserve the o-ring, but does not assist the o-ring
seal.
4. Check the DS51 bulkhead connector threads for debris. Gently wipe away with
a soft, lint free cloth or a cotton swab to clean the threads. Afterwards, lightly
lubricate them.
5. Remove the batteries and store the DS51 with the battery door lightly screwed
on (this will allow any hydrogen/air mixture to escape the battery compartment
and avoid placing unnecessary pressure on the o-ring that could cause it to
flatten).
n addition to these procedures, it is strongly recommended that this strobe be
returned to kelite periodically for inspection and water pressure testing. deally
your DS51 should undergo this process every two years or 100 dives, whichever
comes first.

TR UBLESH TING
STR BE WILL N T FIRE
1. Check the DS51 ready light. Turn the strobe’s mode switch to OFF and then
back to TTL. Make sure that the switch has actually clicked into position.
2. Check that the batteries are inserted according to the “+” and “-” markings.
t is possible to buy bad “new” batteries, so check the voltage output with
a meter if possible. f using NiCad or NiMH batteries, make sure the charger is
operating properly and that the batteries are fully charged.
3. Check the mode switches on the camera and strobe.
4. Check the cord connections at the camera and strobe.
5. When using a sync cord between the camera and strobe, disconnect the cord
from the camera but leave the cord connected to the strobe. Then use the two
ends of a bent paper clip to connect different receptacles on the flash cord
contacts, as detailed in the diagram below. This process, known also as
“shorting,” creates a temporary circuit that can test-fire the strobe.
Caution: When creating a circuit via paper clip, or “shorting,” pay close attention
to which two receptacles you connect. f you short across the wrong receptacles
on a TTL sync cord, you may damage the DS51 electronics.
The specific receptacles to connect with the paper clip vary based on the type
of cord you own. Please refer to the diagram of two types of flash cord contacts.
Ikelite TTL Cord: Point the raised half-circle at the end of the cord encompassing
the receptacles towards you, per the above diagram. Place one end of the paper
clip on the center receptacle and one end on the lower right-hand receptacle.
The DS51 should flash.
Nikonos TTL Cord: Point the indexing groove at the end of the cord towards you,
per the above diagram. Place one end of the paper clip on the top-most, center
receptacle and one end on the lower, right-hand receptacle. The DS51 should flash.
f the DS51 flashes, the source of the problem lies somewhere in the camera.
f the DS51 does not flash, please send both the strobe and cord used in the test to
an authorized kelite dealer or to kelite (see “Returning Products for Service”
on page 20).
Do not attempt to repair the strobe or cord yourself. This may cause
further damage and void your kelite limited warranty.
