The Conversion Circuitry default is set to TTL. To switch between
TTL and Manual Modes, depress both Mode Buttons at the same
time and keep them depressed until you see the desired Yellow
LED Mode illuminate.
•• TTTTLL M
Mooddee (indicated when the Yellow LED directly below TTL is
illuminated). TTL Mode is the default setting. When the DS
Substrobe is powered ON, the Yellow TTL LED will illuminate.
None of the Red LEDs will illuminate. This indicates that NO (+)
plus or (-) minus compensation is selected. Depress the Mode
buttons to /- compensation. Note that the TTL +/-
compensation values are in the yellow bar with the heading TTL.

Maannuuaall M
Mooddee (indicated when the Yellow LED directly below
the M is illuminated). When the Manual Mode is selected, the
Red LED directly below the F (full power) will illuminate. Note
that the Manual minus (-) compensation values are in the black

If the port is installed before the
camera is inserted into the housing,
look on the inside of the housing
front at the port seal. Check to see
that the o’ring is properly sealed as
shown in figure 1 and not extruded as
shown in figure 2.

After installing the port, turn the Zoom Control knob on the
housing. If the Zoom Control is difficult to turn, the gear sleeve
may be warped. If so, reduce or omit any rubber installed on the
Zoom Clamp. (Fig.H on pg.10).
If the Zoom Clamp is still warped,
use of the #5509.28 package may be required. (See page 7)

The housing has Conversion Circuitry built into the camera tray.
When used with Ikelite DS Substrobes, the Conversion Circuitry
provides real Olympus TTL flash exposure with over and under-
exposure compensation of two f-stops in half-stop increments.
The Conversion Circuitry also offers Manual exposure control
with 3 1/2 f-stops of under-exposure control in 1/2 stop
increments.
The Conversion Circuitry is powered by the Ikelite DS Substrobe
when connected to the housing with the #4103.51 single or
#4103.52 dual sync cord.
See page 16 for DS Substrobe compatibility with the Conversion
Circuitry.

If the camera is busy with a function such as displaying a
photograph on the LCD panel the Conversion Circuitry cannot
be accessed to make changes. Wait until the camera has
finished with any activity before making changes through the
Conversion Circuitry.
