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
N N o o t t e e : :
• When the DS is connected directly to the camera the camera must feature
compatible TTL/auto exposure to utilize this mode (See "TTL/Auto Exposure " page
and "Compatible Cameras " page )
• The TTL/auto firing mode must be selected when connecting the EV Manual

(Fig ) Shows the mode switch in the manual exposure mode with the DS
Substrobe 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 DS Substrobe 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 (See "Exposure Guide " page
If the subject in the photo is underexposed (dark) you must move closer to the
subject If 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 DS provides five reductions in power in one half f stop increments from the full
power setting (Fig ) for example shows the mode switch set to

Always turn the substrobe 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 N N o o t t e e : : D D o o n n o o t t remove the knob from the battery door
C C a a u u t t i i o o n n : : The battery compartment is sealed separately from the main electronics

Be aware of the position of the o ring around the perimeter of the battery door
N N o o t t e e : : Keep the o ring and sealing surfaces clean
Lightly lubricate the exposed portion of the o ring with the Ikelite silicone lubricant
provided Use only enough lubricant to cover the o ring; wipe off any excess with a
clean cloth (See "Lubricant" on page

Install four AA cell batteries: alkaline NiCad or NiMH Refer to the " " and " – "
markings in the battery compartment to help properly install the batteries If the
batteries are installed incorrectly it may damage the strobe's electronics
Always carry spare batteries; weak batteries cause many camera and strobe
problems It's time to replace the batteries when after the DS
light remains dark for seconds or longer (See "Strobe Ready Light " page )
N N o o t t e e : : It is possible to buy bad "new" batteries; check the voltage output with
a meter

Again check that the o ring and sealing surfaces are clean and that the o ring is
lightly lubricated Make sure the o ring is back in its original position
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 C C a a u u t t i i o o n n : : D D o o n n o o t t
