Types of Batteries
This flash unit uses four AA-size 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 fire 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.
■
Using the Optional External Power
Source
Use the optional TR Power Pack-3 (upcoming product,
sold separately) as an external power source.
●
For information on how to use the TR Power
Pack-3 and connect to the flash unit, refer to the
manual provided with the TR Power Pack-3.
●
For information on how to recharge the flash unit
using the TR Power Pack-3, refer to “Charging
the AF540FGZ with the Optional External Power
Source” on page 16.
●
The TR Power Pack-2 cannot be used with the
AF540FGZ for mechanical reasons.
The external power source uses six C-size alkaline
batteries (LR14).
(Nickel cadmium (Ni-Cd) batteries cannot be used in the
TR Power Pack-3.)
If charging time takes more than 20 seconds, the
batteries have been exhausted and should be replaced
with new batteries. If the flash unit is used with
exhausted batteries, the settings may return to their
default configuration.
