Thank you for choosing Bolt, and congratulations on the purchase of your Bolt
PP-400DR Power Pack for Portable Flash. This rechargeable large-capacity
lithium-ion battery pack will supply up to 1400 flashes (depending on flash unit
and power setting) and fast recycling times for one or two portable flashes at the
same time. It’s compatible with most on-camera flashes, including Nikon, Canon,
Sony, Bolt, Sunpak, Vivitar, and Metz.
This Bolt Cyclone DR includes one removable and interchangeable battery
pack—the PP-400BP (additional PP-400BP batteries are available separately).
When the battery begins to lose power, it can be removed in just a few seconds
and replaced with a new, fully charged PP-400BP battery—you can extend your
shoot as long as you need to, without worrying about recharging.
The Bolt Cyclone DR features a microcontroller unit (MCU) circuit design with
integrated software and hardware protection for more efficient energy use as
well as heat-resistant lightweight construction.

Using Your Flash with Your Cyclone DR
Your Cyclone DR can recycle in just 1 second with many popular flash units to keep you shooting and ensure
that you don’t miss important moments. With your flash firing at full power, it can power between 1200 and
1400 flashes, depending on the specific unit you’re using. It can power thousands of shots in automatic mode
with some flash units.
To get the best use out of your Cyclone DR:
• Use in environments with moderate temperatures.
•Don’t fire more than 40 full-power flashes in a row. Doing this can overheat and even damage your flash.
The Cyclone DR has a much higher power output than the typical built-in battery of a flash unit. Refer to
your flash unit’s manual for information on its continuous full-power flash capacity and limitations.

clip. To do this, loosen the screws securing it with a Phillips screwdriver, remove the clip, then tighten the
screws again.
• Shoulder strap. Thread the shoulder strap through the built-in lugs on the Cyclone DR and through the strap
clips and buckles, as shown here. After threading it, pull it tight to take up any slack. Always make sure that
your strap is attached securely; dropping the Cyclone DR can damage it.
