Port Seal Inside View

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.

To Remove Port

To remove the port lift up on each

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 draw 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’s 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 it clicks into place. It may help to slightly rotate the port as you push in on the port lock. When the port lock clicks into place the Release Button will drop down against the port lock.

Check around the perimeter of the port seal to see that the o’ring is properly sealed and not extruded.

Using External Strobes Cont.

Using the Conversion Circuitry (Set DS Substrobe to TTL mode)

• Mode and Compensation Buttons

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.

• TTL Mode (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 isselected. Depress the Mode buttons to select +/- compensation. Note that the TTL +/- compensation values are in the yelow bar with the heading TTL.

• Manual Mode (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 bar with the heading M. (Set DS Substrobe to TTL mode)

Release Button and slide the port lock away from the port.

Caution:

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 stillwarped, use of the #5509.28 package may be required.(See page 8)

NOTE: DS Substrobe Up-date may be required. DS50 Substrobes

• DS50 SubStrobes with a Serial Number below 63,850 can not be updated to operate with the TTL Conversion Circuitry.

• DS50 SubStrobes with a Serial Number between 63,850 and 69,999 operate with the TTL Conversion Circuitry, but require update to provide optimum performance.

• DS50 Substrobe with a Serial Number of 70,000 or higher or with one of the two following labels in the battery compartment provide optimum performance with the TTL Conversion Circuitry. DS125 Substrobes

• DS125 Substrobes with a Serial Number below 2,500must be updated to operate correctly with the TTL Conversion Circuitry.

• DS125 Substrobes with a Serial Number between 2,501 and 4,900 operate with the TTL Conversion Circuitry but require update to provide optimum performance.

• DS125 Substrobe with a Serial Number of 5,000 or higher or with one of the two following labels in the battery compartment provide optimum performance with the TTL Conversion Circuitry.
