■Types of Batteries

This flash unit uses four AA batteries of the same type, as shown below.

Alkaline battery (LR6) Lithium battery (FR6)

Nickel-Metal Hydride battery (Ni-MH)

(Nickel manganese (Ni-Mn) and nickel cadmium (Ni-Cd) batteries cannot be used.)

●For information about recycling times and total number of flashes, refer to “Specifications” on page 20.

●If the ready lamp does not light up when you turn on the power (page 8), the batteries may be exhausted or not inserted correctly. Verify the orientation of the batteries or, if the indicators and ready lamp still do not light up, replace them with new batteries.

●If charging time takes more than 20 seconds, the batteries are exhausted and should be replaced with new batteries.

●If you let the flash unit discharge successively using lithium batteries, the batteries will overheat, activating a safety circuit that temporarily disables the flash unit. If this occurs, rest the flash unit so that the temperature of the batteries returns to normal.
