IINNTTRROODDUUCCTTIIOONN
Thank you for purchasing an Ikelite Substrobe. Ikelite brings over 45 years of
underwater photographic and lighting experience to the strobe market. Ikelite
Substrobes are designed and built in the USA by Ikelite to suit both the professional and
the amateur photographer.
The purpose of a strobe is to illuminate the subject and assist the camera in taking vivid
pictures. The Ikelite DS160 Substrobe is equally suited for general and wide-angle
photography, covering up to a full 100° angle with a diffuser.
This strobe is everything you need for stunning photos.
SSTTAARRTTIINNGG OOUUTT
Before using the Ikelite DS160 Substrobe, please read this owner’s manual thoroughly
and retain it for future reference. Ikelite recommends becoming familiar with the
features and functions of the Ikelite DS160 Substrobe 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.
SSTTRROOBBEE CCOOMMPPAATTIIBBIILLIITT
The DS160 Substrobe is compatible with all Ikelite TTL systems and current digital
cameras, as well as all older TTL film cameras including the Nikonos system. A variety of
sync cords, sensors, and TTL adapters are available to connect to almost any camera
system currently on the market.
SSTTRROOBBEE PPOOWWEERR
The DS160 recycles in a quick 1.5 sec from full discharge. When fired at a fractional
power — whether in TTL or manual mode — the strobe recycles virtually
instantaneously. Number of flashes per full charge will increase dramatically in most
cases when using in TTL mode with a compatible camera system. The powerful DS160 is
adjustable in 10 half-stop increments for precise control over your exposure when used
in manual mode.

Always turn the Substrobe OFF before opening.
OOPPEENNIINNGG TTHHEE SSTTRROOBBEE
Turn the strobe OFF, and place the strobe face down on a flat surface.
Slide the locking lever out by either grasping the sides of the lever and pulling it out OR
use your thumb to apply slight pressure to the top of the lever and slide it out.
Flip the lever up and then rotate the lever counter-clockwise 90°. The internal spring
automatically pushes open the strobe. Lift the rear section off of the strobe front (See
illustrations on page 7). The rear section is the NiMH battery pack for the strobe.
The NiMH pack does NOT remain waterproof when removed from the strobe.
Therefore, we suggest keeping the open portion of the NiMH pack pointed down while
removing to eliminate the possibility of water droplets falling inside. The NiMH batteries
remain permanently secured inside the pack.
The front section of the DS161, which houses the main electronics, is safely sealed
separately from the NiMH pack. The front section will remain waterproof when the
NiMH pack is removed. However, avoid salt-water contact with the battery pins.
Damage/corrosion can cause a short circuit. DDOO NNOOTTdisassemble the strobe or the
NiMH pack. We suggest storage of your strobe with the locking lever OPEN to allow
any hydrogen/air mixture to escape.
OO--RRIINNGG
The o-ring is located on the inside rim of the NiMH pack. Keep the o-ring and the sealing
surfaces clean. DDOO NNOOTTstretch the o-ring when cleaning. It is not necessary to lubricate
the o-ring. Never use spray lubricant because it may crack the plastic.
RREECCHHAARRGGEE TTHHEE BBAATTTTEERR PPAACCKK
See "NiMH BATTER PACK" section for recharging information (page 8).
CCLLOOSSIINNGG TTHHEE SSTTRROOBBEE
Make sure the power switch has been rotated to the off position.
Place the front of the strobe face down on a flat surface. Check that the o-ring and
sealing surfaces are clean; make sure the o-ring is positioned properly inside the rim of
the NiMH pack. Place the locking lever in the open position (slide the lever out, flip the
lever up, and rotate the lever counterclockwise 90 degrees until it stops).
Align the front and rear sections of the strobe. Lower the NiMH pack onto the front
section of the strobe. Proper alignment of the two sections is extremely important to
avoid possible damage to the internal components.
To seal the strobe, simply press down slightly on the rear of the NiMH pack and rotate
the lever clockwise 90 degrees until it stops. Flip the lever down and then slide the lever
into the locked position to properly seal the strobe.

The Ikelite DS160 strobe combines high intensity output and wide coverage angle
in a compact, versatile design. This strobe features 160 watt-sec. intensity and covers
a full 100° using the diffuser. Special soft-lite reflector provides rich reds, oranges, and
warmer flesh tones.
The Ikelite DS160 strobe is pre-flash compatible and operates with both traditional film
cameras and digital still cameras. Multiple firing modes are featured, including TTL/Auto
exposure.
The DS160 electronics are safely sealed separately from the battery pack. The industrial
grade NiMH batteries recycle in an incredible 1.5 seconds and the NiMH pack
is easily interchangeable with a spare unit. When in the “BBaatttt ww//LLiittee” position, the fuel
gauge references the remaining battery capacity. Aim the DS160 and illuminate your
subject's colors with the built-in modeling light / night diving light.

The #4061 DS160 comes standard with rechargeable NiMH battery pack and flash
diffuser (page 9). The NiMH battery pack requires #4066.1 Smart Charger (page 19), not
included except with certain strobe packages.
Rechargeable NiMH battery pack #4066.5 is compatible only with Ikelite's DS160 and
DS161 strobe. It is the only battery pack usable in the DS160 AND DS161. The rear
section of the strobe is the NiMH battery pack for the strobe. Additional NiMH packs
(rear sections) #4066.5 are available through an Ikelite dealer. Battery pack is also
compatible with older DS125 strobes.
A fully charged NiMH pack provides at least 222255 ffuullll ppoowweerr ffllaasshheess. It consists of six
sub-C-cell industrial grade NiMH batteries (1.8Ah rating).
The NiMH pack does NOT remain waterproof when removed from the strobe.
Therefore, we suggest keeping the open portion of the NiMH pack pointed down
while removing to eliminate the possibility of water droplets falling inside. The
NiMH batteries remain permanently secured inside the pack.
DDOO NNOOTTdisassemble
the NiMH pack or charger.
The DS160 accepts the same #4066.5 NiMH module used on our older DS125 Substrobes.
If you intend to use an older battery pack on your new Substrobe, please reference the

Recharge the NiMH pack after each use. DDOO NNOOTTfully discharge NiMHs as this shortens
the battery life. Recharge the NiMHs if the modeling light dims or if the recycle time
exceeds 8-10 seconds; batteries are nearly depleted. Store the NiMH pack fully charged and
recharge the pack for a few hours each month. In our application, the NiMHs should NOT
develop a memory. Fully discharging the NiMHs or allowing the NiMHs to completely lose
a charge does far more damage than any risk of NiMH memory.

An optional paddle-type or ball-type mount can be mounted to the underneath side of
the strobe. The mount slides into the strobe base and is secured with a screw (supplied
with optional mount). Make sure to slide the mount into the strobe base until it stops.
Be careful to not cross-thread the screw when tightening the mount. The DS160 Shroud
can be rotated slightly to gain better access to the strobe base with a screwdriver.
Although not necessary, you can apply a small amount of Ikelite lube around the screw
threads before attaching the strobe mount. Use Ikelite lube only which is supplied with
the DS161 strobe. This will reduce the possibility of seizing and allow removal of the
screw should the mount need to be removed. Removing the mount for long storage
periods will also reduce the possibility of seizing.

Bulkhead Cap
The female Ikelite bulkhead connector permits different Ikelite sync cords or the Ikelite
EV manual controller sensor to be connected to the strobe. The sync cord or sensor relays
a signal from the camera to the substrobe that tells the DS160 when to flash.
The removable waterproof bulkhead cap seals the bulkhead connector when neither a
cord nor a sensor is connected to the DS160. The strobe’s bulkhead connection must be
sealed to remain waterproof (page 12).
CCaauuttiioonn::
•DDoo nnoottleave the sync cord or sensor connected to the camera or strobe
for prolonged periods as electrolysis could occur and make removal of the
equipment impossible.
•DDoo nnoottdisconnect the sync cord or sensor from the housing or strobe when
underwater or when wet. These items are not waterproof when disconnected.
• Make sure there is no debris on the sync cord o-ring and the sync cord connector
is aligned properly when attaching to the strobe bulkhead (page 12).
CCOONNNNEECCTTIIOONN TTOO SSTTRROOBBEE
To connect either a sync cord or sensor to the DS160 Substrobe, follow these instructions:
1. Turn the substrobe 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 Ikelite housing to an Ikelite
Substrobe, both cord ends are identical; either end can be connected to the
strobe.
3. The connector threads are very fine; do not cross thread. If it is difficult
to turn the knurled retaining ring on the cord or sensor, you are likely
cross-threading. This can make removal of the strobe or sensor impossible.
Hand-tighten the knurled retaining ring on the cord or sensor. Push the end of
the cord further into the bulkhead connector and continue to tighten the knurled
retaining ring. DDoo nnoottuse pliers or a tool when tightening. It could damage the
cord or strobe.

For use with the following types of systems:
- Ikelite or non-Ikelite housings without external strobe connector
The EV Manual Controller #4100.6 is required to use the DS160 as a slave strobe. The
EV Controller watches the camera's built-in flash and triggers the strobe at the
appropriate time.
Set the DS160 mode switch to "TTL" to utilize the power settings on the EV Manual
Controller. If the DS160 is set to a manual exposure mode, the power settings of the EV
Manual Controller are ignored.
The camera must be set to a "forced flash" mode, usually designated by a lightning bolt,
in order for the DS160 to fire consistently in every photo. Both the camera's built-in
flash and the DS160 must recycle completely before taking another flash photo.
Most digital cameras fire one or more short preflashes to help the camera determine
focus, exposure and color balance. After the preflash(es), the camera's built-in flash fires
to illuminate the subject while the photo is taken. Both the EV Manual Controller and
the Substrobe DS160 are preflash compatible. The internal switches on the EV Controller
must be set properly for the DS160 to fire at the correct time. Refer to the EV Manual
Controller instruction manual for more information.
If the DS160 fires at the incorrect time resulting in a dark photo, the preflash setting is
most likely incorrect. Check both the preflash switch on the EV Controller and the
camera's exposure mode. Some digital cameras such as the Canon G-series fire a preflash
in Auto, Program, shutter priority and aperture priority modes, but not manual exposure
modes.

- Non-Ikelite housings for digital cameras with Nikonos-style strobe connector
Connect the strobe using an appropriate Ikelite sync cord. The DS160 must be used in
manual exposure modes. Strobe output is not automatically adjusted for proper
exposure when set to TTL(Auto) mode.

For use with the following types of systems:
- Ikelite housings for digital cameras with TTL conversion circuitry
- Ikelite housings for film cameras
- Nikonos V, RS cameras
- Non-Ikelite housings for digital cameras and compatible TTL adapter
Connect the strobe using an appropriate Ikelite TTL sync cord. Digital dSLR cameras
require the use of a Digital TTL sync cord. These cords are designated by a blue band at
one end. The DS160 may be used in TTL(Auto) or manual exposure modes.
TTL (thru-the-lens) exposure automatically compensates for aperture, distance and
filters. Because there's such a wide range of apertures and subject distances,
photographers wanting to easily balance lighting and control close-up photographer
should select the TTL(Auto) exposure mode. 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 module in the back of the housing
(if applicable).
If an exposure compensation module is featured in the back of
the housing, strobe output may be controlled manually while
the strobe itself is left in TTL(Auto) mode. In order to use the
manual exposure modes on the strobe itself, the housing
module must be set in a manual position.
When using a non-Ikelite TTL adapter or third party conversion
circuitry, please refer to the product's instructions for help in
using the DS160 with this setup.

Use the modeling light to aim the strobe. Look thru the camera's viewfinder, and aim
the strobe so that the modeling light shines in the center of your picture area. If your
subject distance greatly changes, you should recheck the positioning of the strobe.
When using auto-focus cameras, the modelng light may be required in low light levels to

The middle #2 LED on the fuel gauge functions as the visual ready light.
The DS160 also features a confidence light that will glow if the strobe properly exposes
the picture. The #3 LED on the fuel gauge will glow GREEN for three seconds if the
DS160 strobe quenches, indicating that the strobe has provided proper exposure. This
green confidence light illuminates only in the TTL exposure mode. If no green light
appears, check the image for possible under-exposure. When the strobe has recycled
again, the ready light will again glow red indicating that the strobe is fully powered and
ready to fire. If the strobe ready light does not glow red, the batteries may be expended.
our camera’s ready light “lightning bolt” in the camera viewfinder may blink while the
DS160is recycling and then glow solid when the DS160 is fully charged. Nikon dSLRs and
older Canon dSLR models such as the 20D and Rebel XT will always display a solid glow

When using a TTL/Auto exposure camera (film or digital) in an Ikelite TTL compatible
housing connected to the DS160 strobe by sync cord, the flash ready light in the camera
viewfinder and the DS160 ready light will both glow when the Substrobe has recycled and
is ready to fire.
If the Ikelite housing does not feature TTL compatible circuitry, then the ready light
in the camera viewfinder would not be triggered when the strobe has recycled.
TTrriiggggeerreedd vviiaa SSllaavvee SSeennssoorr
When using the DS160 strobe with the optional EV-Controller (without optional
sync cord), the strobe is not electronically connected to the camera. Therefore, the ready
light in the viewfinder of the camera only indicates when the on-camera flash has
recycled. Reference both the camera and DS160 ready lights to make sure both flashes
have fully recycled before taking the next picture.

When the switch is rotated to the “Batt w/Lite” position, the fuel gauge on the side of
the strobe will display 0, 1, 2, or 3 red LED lights indicating the remaining charge in the
battery pack (see below). A fully charged NiMH pack will provide at least 225 full power
flashes and all 3 LED's should light. When no LED's are illuminated, then the battery
capacity is low and you may have less than 36 full power flashes remaining. For general
guidelines, refer to the following list:
• 3 LED’s - above 75%
• 2 LED’s - above 50%
• 1 LED - above 25%
• No LED - less then 25%
CCOONNFFIIDDEENNCCEE SSIIGGNNAALL
The DS160 strobe features a confidence signal indicator light that will glow if the strobe
properly exposes the picture. The #3 LED on the fuel gauge will glow GREEN for three

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.
IINNSSUURRAANNCCEE
It is recommended that you add an aallll--rriisskk ffllooaatteerrto your homeowner’s and/or
renter’s insurance policy to cover your equipment against loss or damage. While the
Ikelite DS160 Substrobe has a limited warranty against manufacturing defects, it does
not cover customer neglect.
TTIIPPSS
• 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 of approximately 100°.
• If possible, measure the light with a meter and set the camera aperture
accordingly. A narrower aperture darkens the background; a wider aperture
lightens it.
• Add a second Substrobe DS160 for more natural looking photos and wider angle
of coverage when shooting both still and video images. Add a second DS
Substrobe using either the EV Manual Controller #4100.6 or an appropriate dual
sync cord.
• Purchasing a spare #4066.5 NiMH Battery Pack is recommended if you dive
often. Weak batteries are the cause of many strobe and camera problems.
•DDoo nnoottfire the strobe more than 15 times in rapid succession. If this does happen,
allow the DS160 to cool off for at least 10 minutes before resuming photography.
LLUUBBRRIICCAANNTT
• Use oonnllyyIkelite brand silicone lubricant with Ikelite brand
o-rings; other brand lubricants can cause the Ikelite o-rings to swell in size.
•DDoo nnoottuse spray lubricant; it can crack the plastic parts of the strobe.
• Ikelite 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.

our Ikelite DS160 Substrobe should be given the same care and attention as your
other photographic equipment. After using your strobe in water, please follow these
instructions to ensure the DS160’s longevity and good working order.
CCLLEEAANNIINNGG AANNDD SSTTOORRAAGGEE
1. Always rinse the exterior of the DS160 with fresh water after use, especially after
exposure to salt water. While rinsing, turn the mode and power switches to free
salt or debris that might have accumulated in the DS160’s recesses during the dive.
The strobe can be cleaned by soaking it in a mild soapy solution. Use liquid soap;
RINSE and DR the strobe before storage.
2. Check the NiMH battery o-ring sealing surface for any debris and gently
wipe it away with a soft, lint free cloth.
3. Check the DS160’s 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.
4. The o-ring #0132.36 is located on the inside rim of the DS160 battery pack. Keep
the o-ring and the sealing surfaces clean. DDOO NNOOTTstretch the o-ring when cleaning.
It is not necessary to lubricate the o-ring. Never use spray lubricant because it may
crack the plastic.
5. Keep the strobe bulkhead connector threads clean and lightly lubricated. Also keep the
sync cord o-ring and threads clean and lightly lubricated.
6. Recharge the NiMH pack after each use; DDOO NNOOTTfully discharge the NiMHs because
you will shorten the battery life. Store the NiMH pack fully charged, and recharge the
pack for a few hours each month. DDOO NNOOTTdisassemble the battery pack.
7. The strobe is factory sealed; DDOO NNOOTTdisassemble.
In addition to these procedures, it is strongly recommended that this strobe be returned
to Ikelite periodically for inspection and water pressure testing. Ideally your DS160
should undergo this process every two years or 100 dives, whichever comes first.
MMAAIINNTTEENNAANNCCEE
CCaauuttiioonn::
• The DS160’s bulkhead connector is not waterproof and must be capped when not
connected to a cord or sensor. Using a DS160 underwater with the bulkhead
connector uncapped or unconnected will cause the strobe to flood. DO NOT
continue to use a flooded strobe; return to Ikelite for repair.
• The strobe is factory sealed; ddoo nnoottdisassemble. Disassembly will void your
Ikelite DS160’s limited warranty.
•DDoo nnoottcontinuously fire the strobe more than 15 times above water in rapid
succession. If this does happen, allow the strobe to cool down for at least 10
minutes.

1. Make sure the NiMH battery pack is fully charged.
2. Check the DS160’s ready light. Turn the strobe’s mode switch to OFF and then
back to ON. Make sure that the switch has actually clicked into position.
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.
CCaauuttiioonn::When creating a circuit via paper clip, or “shorting,” pay close attention
to which two receptacles you connect. If you short across the wrong receptacles
on a TTL sync cord, you may damage the DS160’s 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.
IIkkeelliittee TTTTLL CCoorrdd::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 DS160 should flash.
NNiikkoonnooss TTTTLL CCoorrdd::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 DS160 should flash.
If the DS160 flashes, the source of the problem lies somewhere in the camera.
If the DS160 does not flash, please send both the strobe and cord used in the test to
an authorized Ikelite dealer, or to Ikelite; see “Returning Products for Service”
on page 24.
DDoo nnoottattempt to repair the strobe or cord yourself. This may cause
further damage and void your Ikelite limited warranty.

The DS160 electronics are safely sealed separately from the battery pack. Should the
battery pack flood, flush with fresh water and dry thoroughly. Determine the cause of
flooding. REPLACE THE COMPLETE BATTER PACK #4066.5. Never re-use batteries
that have been wet. The water could create an internal short circuit at some later date
causing a potential explosion. DO NOT disassemble the strobe, NiMH pack.
Send the strobe head in for service if there is any discoloration of the battery pins.
