1. Caution A Do not leave the sync cord or sensor connected to the camera or strobe for prolonged periods as electrolysis could occur and make removal of the equipment impossible Do not disconnect the sync cord or sensor from the housing or strobe when underwater or when wet These items are not waterproof when disconnected Make sure there is no debris on the sync cord o ring and the sync cord connector is aligned properly when attaching to the strobe bulkhead page 14 CONNECTION TO STROBE To connect either a sync cord or sensor to the DS161 Strobe follow these instructions 1 Turn the strobe to OFF and make sure all components are dry Clean and lightly lubricate the stem o ring and the bulkhead connector threads Check the o ring for nicks or cuts 2 Note the positioning of the receptacles and pins on the end of the cord Properly align the end of the cord and insert it into the strobe bulkhead connector When using the 4103 51 cord which connects an Ikelite housing to an Ikelite Strobe both cord ends are identical either end can be connected to the strobe 3 The connector threads are very fine do not cross thread If it is difficult to turn the knurled retaining ring on the cord or sensor you are likely cross threading This can make removal of the strobe or sensor impossible Hand tighten the knurled retaining ring on the cord or sensor Push the end of the cord further into the bulkhead connector and continue
2. The front section of the DS161 which houses the main electronics is safely sealed separately from the battery pack The front section will remain waterproof when the battery pack is removed However avoid salt water contact with the battery pins Damage corrosion can cause a short circuit O RING The o ring is located on the inside rim of the battery pack Keep the o ring and the sealing surfaces clean DO NOT stretch the o ring when cleaning It is not necessary to lubricate the o ring Never use spray lubricant because it may crack the plastic CLOSING THE STROBE Make sure the power switch has been rotated to the OFF position Place the front of the strobe face down on a flat surface Check that the o ring and sealing surfaces are clean make sure the o ring is positioned properly inside the rim of the battery pack Place the locking lever in the open position slide the lever out flip the lever up and rotate the lever counterclockwise 90 degrees until it stops Align the front and rear sections of the strobe Lower the battery pack onto the front section of the strobe Proper alignment of the two sections is extremely important to avoid possible damage to the internal components To seal the strobe simply press down slightly on the rear of the battery pack and rotate the lever clockwise 90 degrees until it stops Flip the lever down and then slide the lever into the locked position to properly seal the strobe LI I

4. CAMERA READY LIGHT Triggered via Sync Cord When using a TTL Auto exposure camera film or digital in an Ikelite TTL compatible housing connected to the DS161 strobe by sync cord the flash ready light in the camera viewfinder and the DS161 ready light will both glow when the Strobe has recycled and is ready to fire If the Ikelite housing does not feature TTL compatible circuitry then the ready light in the camera viewfinder would not be triggered when the strobe has recycled 19 RECOMMENDATIONS VISUAL INSPECTIONS Visual inspections are important Take the time to examine the entire assembled setup strobe camera housing arms etc above water An improper seal or loose connection can cause a lot of damage Always check for leaks once you place the equipment in the water INSURANCE It is recommended that you add an all risk floater to your homeowner s and or renter s insurance policy to cover your equipment against loss or damage While the Ikelite DS161 Strobe has a limited warranty against manufacturing defects it does not cover customer neglect TIPS Photograph through as little water as possible move in close Maximum recommended shooting distance underwater is 1 8m 6 Use the diffuser for softer lighting or a coverage angle of approximately 100 If possible measure the light with a meter and set the camera aperture accordingly A narrower aperture darkens the background a wider aperture lightens
5. it Add a second DS161 Strobe for more natural looking photos and wider angle of coverage when shooting both still and video images Add a second Strobe using either the EV Manual Controller 4100 6 or an appropriate dual sync cord Purchasing a spare Li ion Battery Pack 4067 is recommended if you dive often Weak batteries are the cause of many strobe and camera problems Do not fire the strobe more than 15 times above water in rapid succession If this does happen allow the DS161 to cool off for at least 10 minutes before resuming photography LUBRICANT Use only Ikelite brand silicone lubricant with Ikelite brand o rings other brand lubricants can cause the Ikelite o rings to swell in size Do not use spray lubricant it can crack the plastic parts of the strobe Ikelite brand silicone lubricant is provided for the sync cord stem o ring and the bulkhead connector threads Use only enough lubricant to lightly cover the area being applied wipe off any excess with a clean cloth Lubricant only reduces friction it is not a sealant 20 MAINTENANCE The Ikelite DS161 Strobe should be given the same care and attention as your other photographic equipment After using your strobe in water please follow these instructions to ensure the DS161 s longevity and good working order CLEANING AND STORAGE 2 Always rinse the exterior of the DS161 with fresh water after use especially after exposure to salt wa
