This housing has Conversion Circuitry built into the camera
tray. When used with Ikelite DS Substrobes the Conversion
Circuitry provides real Canon eTTL flash exposure with over and
under-exposure compensation of two f-stops in half-stop
increments.
The Consversion 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 12 for DS Substrobe compatibility with the Conversion
Circuitry.

If the port is installed before the
camera is inserted into the housing,
look on the inside of the housings 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.11).
If the Zoom Clamp is still warped,
use of the #5509.28 package may be required. (See page 7)

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 (+)
