Precautions

△

• Please read and follow these instructions, and keep this manual in a safe place.
• Do not attempt to disassemble or repair this product. There are components inside that can produce a hazardous electric shock.
• Keep this product and AA batteries away from children.
• Clean the unit with only a soft, dry cloth.

• If you detect smoke or a burning smell coming from the battery pack, immediately stop operation. Once smoking has subsided, remove the batteries to prevent the product from igniting or melting, and take the product to an authorized service center for repair.

• Keep this unit away from water and any flammable gases or liquids.

• Remove all batteries from the battery pack before long-term storage. Do not store or use this product at temperatures above 104°F (40°C).
• To avoid overheating and damaging your flash unit, wait at least 10 minutes after 20 continuous flashes at full power. Refer to your flash unit's manual for information on its continuous full-power flash capacity and limitations.
  • Images are for illustrative purposes only.

Battery Warnings

• Always follow the warnings and instructions printed on the batteries to avoid activities that could cause the batteries to leak corrosive liquid, generate heat, or explode.
• Use in environments with moderate temperatures. When some battery types get cold, they lose some of their ability to supply power. However, this does not mean that they have lost their charge, and they will regain the ability to supply power when their temperature returns to a more moderate level.

• To conserve battery life, turn the flash unit off or disconnect the Compact Battery Pack from it during long standby periods. Very little power is consumed when the pack is in standby mode. The amount may vary according to working conditions and the specific flash model used with the pack.

• High temperatures can cause some battery types to drain more quickly.

• Dispose of batteries properly. Never heat them or throw them into a fire, as this could cause the batteries to leak corrosive liquid, generate heat, or explode.
• Don't fire more than 20 full-power flashes in a row, as this can overheat and damage your flash. Refer to your flash unit's manual for information on its continuous full-power flash capacity and limitations.

To install batteries, unplug the battery pack from your flash unit and follow these steps:

1. Press down on the battery compartment cover and slide the cover in the direction of the arrow.

Connecting to Your Flash

Align the flash cable connector with the separate flash power cord to connect them. Then plug the other end of the flash power cord into your flash.

Make sure the connector is correctly aligned with the pins and alignment grooves on the power port. Forcing a connector into a port upside down can damage both your flash and the Compact Battery Pack connector.

Important!

• The connectors should easily attach. Forcing a connector can damage both your flash and the Compact Battery Pack connector.
• Batteries must be installed in the flash before you connect it to the Universal Compact Battery Pack. Most flash units require batteries to be installed in order to operate.
• You may need to configure the custom function on your flash unit to make it draw power from the battery pack. Refer to your flash unit's instructions for more information.
• Disconnect the Compact Battery Pack from your flash unit before storing it.

Troubleshooting

Problem Solution
The Compact Battery Pack has fresh batteries installed and is connected to a flash unit, but the indicator light does not turn on.	Most flash units require AA batteries for the display and functions to operate.Make sure you have AA batteries installed in the flash unit.The batteries are installed in the wrong orientation. Check each battery in the compartment to ensure that it is installed with the correct orientation.If you’re using only four batteries, ensure they are installed in the left four or right four bays of the battery compartment.
After a long series of continuous flashes, the indicator light is on, but the pack does not power the flash, or it charges slowly.	The battery pack and batteries may have become too hot due to a long series of continuous flashes. This is to protect the flash unit and battery pack from overheating. Allow the system to cool down before using the battery pack.
Recycle times have become slow. Change	all four or eight batteries.If you’re using rechargeable batteries, recharge them.
