The SpeedCycler
Purpose
Most strobes require a few seconds to recycle. In some circumstances a photographer will
need to fire faster than the recycle times permit. The SpeedCycler allows a photographer to
increase shooting rates by cycling from one strobe to the next. This will give each strobe
more t ime to r ecycle.
Operation
With a camera connected to the sync-in, each trigger will sync to one sync-out terminal at a
time. After each trigger, the sync connection moves to the next sync-out terminal in order
1-2-3-4-1... etc. The SpeedCycler will only trigger sync-out terminals that are turned on.
Changing Batteries
For proper operation, p lease use only 'AA' alkaline batteries. Use of standard or rechargeable
batteries is not recommended. Rechargeable batteries have an output voltage lower than
alkaline batteries so reliability and total operating time will suffer.
To change the batteries, hold the unit upside-down with the rounded corners away from you.
Take both thumbs and push the cover away from you. It will slide out far enough to remove
the batteries but cannot co me ou t of the case entirely. Be sure to reinstall the batteries
properly. The plus (+) and minus (-) markings designate the end of the battery that is
showing through the hole. There is also a label inside the battery channel that shows the
proper battery orientation.
Batteries should last for about 300 hours of operation.
Care and Feeding.…
Your SpeedCycler is a rugged piece of equipment. However, to insure continued
reliability, please follow these guidelines:
• Do not subject the unit to high mechanical shock (don't drop it!)
• Damage may occur to some components if the SpeedCycler is stored below -20°C
(-4°F) or above +85°C (185°F).
• Keep your SpeedCycler dry.
• Do not connect any devi ce to this unit unless that device i s approved for use by LPA
Design. Connection to unapproved devices may cause damage and will void your
warranty.
• Remove the batteries when storing the unit for an extended amount of time. Remove
spent batteries promptly.
• To clean the SpeedCycler, use a li ghtly dampened cloth to wipe the exterior surfaces. Do
not use solvents or other cleansers. Do not immerse the unit in any liquid.
