Page 9: Attaching A Sync Connector
1. Remove the bulkhead cap. 2. Lightly lubricate the connector O-ring. We recommend using only Ikelite silicone lubricant to eliminate the possibility of swelling due to incompatible compounds. 3. Line up the pins and receptacles and insert the Sync Cord Plug into the bulkhead. -
Page 10: Battery Compartment
Do not remove the knob from the battery door. The battery compartment is sealed separately from the main electronics. Do not disassemble the strobe. Disassembly will void your Ikelite limited warranty. Opening the Compartment Be aware of the position of the o-ring around the perimeter of the battery door. -
Page 11: Battery Compartment - Continued
Battery Compartment - continued Closing the Compartment Check that the o-ring and sealing surfaces are clean. Make sure the o-ring is back in its original position and free of any debris. Lubricating the o-ring will NOT result in a better “seal” to the strobe and is not necessary. -
Page 12: Compartment Flooding
Should the battery compartment flood, flush the compartment with fresh water and dry thoroughly. Determine the cause of the flooding to the best of your ability. Send the DS51 and other system components involved to Ikelite for inspection and testing as soon as possible. -
Page 13: Strobe Ready Light
Strobe Ready Light The Ikelite DS51 Strobe features a ready light at the rear of the strobe that glows red when the DS51 has recycled and is ready to fire its flash again. This recycling time should not exceed 15 seconds. If the glow disappears for longer than 15 seconds between flashes, it may be time for new batteries. -
Page 14: Mode Switch
Mode Switch The DS51 Strobe mode switch has eight different positions: OFF, TTL/ auto exposure setting, and six manual exposure settings. (Fig.1) (Fig.2) (Fig.3) (Fig.4) OFF position (Fig.1) Shows the mode switch in the OFF position. The white indicator on the knob aligns with OFF. Always turn the strobe to OFF before connecting or disconnecting a sync cord or opening the battery compartment. -
Page 15: Ttl/Auto Exposure Position
Manual Exposure Position (Fig. 3) shows the mode switch in the manual exposure mode with the DS51 Strobe 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 DS51 Strobe in one-half f-stop increments. -
Page 16: Strobe Diffuser
Strobe Diffuser Using the Diffuser The white diffuser can be secured to the front of the DS51 strobe when softer lighting or a coverage angle of up to 80° is desired. The diffuser reduces the DS51 light intensity by one full f-stop. -

3. To remove the diffuser, bend one tab out towards the edge while lifting simultaneously. A lanyard or string can be attached to the diffuser by threading it through the two circular openings near its edge. Attach the other end to the strobe arm to prevent accidental loss.
