I. Safety Warnings
Turn OFF flash if foreign objects or water has entered the the battery
compartment or internal electronics. Continued use in this state may
cause fire or electrical shock. Contact the SeaLife service center for repairs.
The battery chamber is waterproof. If no water has entered the flash
head, the battery chamber may be cleaned without causing permanent
damage to the internal electronics. Rinse the waterproof battery
compartment with fresh water and allow the inside to dry. Replace the
o-rings and apply lube. Install new, fully-charged batteries and test fire
flash. If flash does not operate properly, please contact your local
SeaLife dealer or the SeaLife service center in your country.
Do not attempt to disassemble or access the electronic circuitry for
any reason. The internal electronics uses high-voltage components that
may result in severe electrical shock.
Do not expose flash to heat or direct sunlight for prolonged periods of
time.
Observe all SCUBA dive safety rules and control your buoyancy at all
times. Consult your dive instructor for dive safety questions.

IV. Preparing your flash
INSTALLING BATTERIES:
1) Unscrew waterproof battery cap.
2) Insert 4 new or freshly charged AA
batteries according to the polarity
markings.
3) Align cap notch with key and screw
on waterproof battery cap. Lightly
hand-tighten - Do not overtighten
using excessive force or tools.
Important:
Make sure o-rings are perfectly clean, undamaged and lightly lubed. See
page 23 for important information on maintaining a waterproof seal.

Attach camera (housing) to the tray. Carefully hand-tighten the
mounting screw. Do not over tighten!
Important:
Only attach the flash to cameras/housings with minimum thread
depth of 0.28" (7.2 mm) and using standard 1⁄4-20 tripod type thread.
Never force or over-tighten the screw, or you may damage the
housing seal and threads.

Connecting Flash Link optical cable to the external flash
The Flash includes the Flash Link optical cable (item
#SL96208). The optical cable is used to transmit light from the
camera to the light sensor under the flash head. The external
flash will fire when the light sensor detects light coming from
the end of the cable.
The external flash should come with the optical cable already
attached to the flash head, but it is good to know how the cable
can be removed and re-attached.
1. Turn the cable locking screw counter-clockwise by about 2
rotations to loosen the clamping effect of the lock. Do not
remove the locking screws.
2. Insert the optical cable into the hole of the cable lock until the
cable stops [make sure cable is pushed up all the way].
3. Turn the cable locking screw clockwise to lock the cable into
place [finger tight only – Do not over tighten].

Connecting Flash Link optical cable to SeaLife cameras
For SeaLife cameras:
Attach the other end of the optical cable to the camera adapter
included with your SeaLife camera.
1. Push the optical cable into one of the grooves so it’s locked
firmly into position. The end of the cable must be directed at
the camera’s flash but should not stick out beyond the
adapter. The adapter has two grooves, so you can add another
cable when using two flashes.
2. Attach the Flash Link adapter around the lens and push down
until it locks firmly into place. There are two small locking
mechanisms located on the outer edge of the adapter that
should lock in to the camera housing. Make sure the adapter
is oriented so it is aligned with the recessed flash window.
3. Once the cable and adapter is firmly attached, run the cables
along the bottom of the flash base and up the flash arm. The
cables should be secured to the flash arm using the Velcro ties
provided with your flash accessory.

Connecting Flash Link optical cable to NON-Sealife cameras
The universal cable adapter included with the flash allows you to
attach the optical cable to any underwater camera housing.
Step 1: Cut two small strips of adhesive
backed hook-and-loop fastener
Step 2: Remove adhesive backing strips
and firmly attach above and below the
flash window of the underwater housing.
Make sure housing surface is clean and
dry.
Step 3: Unscrew cable adapter assembly
and insert the larger half through the hole
of the hook-n-loop fastener as shown.
Make sure the “hook” side of the fastener
is facing towards the wide end of the
adapter (towards the camera).
