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 88.
●
If the indicators on the LCD panel or the ready
lamp does not light up, 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 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.
