Ikelite Underwater TTL Housing for Canon EOS 40D - Manual (Page 15)

Installing the Port
There are four port locks on the
front of the housing, see figure
G, page 14. Each port lock has
a Release Button. Lift the
release button and slide each
Port Lock away from the port
opening. In the unlocked
position, the Release Button will
remain in the up position as
shown.
To prepare the port for
installation, remove the port o-ring and lightly lubricate it. The port seal
is a side-to-side seal and requires the o-ring to be lightly lubricated for
easy installation. Put a small amount of lubricant on your fingers and pull
the o-ring through your fingers to lightly lubricate it. Do not stretch the
o-ring. Check that the lip of the port where the o-ring fits and the sealing
surface on the housing are clean. Place the port, with o-ring, into the
housing port opening. Press down on the port firmly and evenly until you
feel the port slide into place. Continue to push down on the port and
push each port lock forward until the lock fully engages. It may help to
slightly rotate the port as you push in on the port lock. Visually inspect
the port lock and confirm that the Port Lock Release Button is seated
flush against the Port Lock Body. Do not rely on an audible "click" to
indicate that the lock is engaged.
Check around the perimeter of the port seal to see that the o-ring is
properly sealed and not extruded, figure 2, page 16.
