Turning off the power switch on the connected camera (except for DSLR-A100) automatically places the flash unit in power-
saving mode.
You can specify the power-saving timer for the flash unit by selecting [External Flash Set.] - [Ext. Flash Cust. Set.] - [Power
Save] from the menu of the camera attached with this flash unit; or the power-saving timer during wireless flash photography
by selecting [WL Power Save].
Checking the remaining battery power
When the batteries are running out of power, the TEST button on the back of this flash unit flashes in orange.
When flashing slowly
The batteries are running out of power. It is recommended that you replace the batteries.
The flash unit, however, is still capable of firing flashes in this state.
When flashing quickly
The flash unit is not capable of firing flashes. Replace the batteries.
Notes on continuous flash firing
If this flash unit fires flashes in quick succession for a short period of time, its built-in safety circuit will be triggered to suspend
flash firing and the flash interval may be forced to extend.
In addition, if the temperature inside the flash unit rises further, the TEST button on the back of the flash unit flashes in red to
indicate that flash firing is disabled for a while (overheated state). In such a case, make sure that you turn the power switch on
the flash unit to “OFF” and leave the flash unit unused for about 20 minutes to let it cool down.
Continuous flash firing causes the batteries inside this flash unit to build up heat. Take sufficient care when you remove the
batteries.
