Power Saving Function - AmazonBasics DF500 Manual De Instrucciones

Operating Instructions
5. S2 MODE
S2 MODE (slave mode 2 or pre-flashing cancel mode) can only be used when
the camera or master flash is on TTL MODE. The camera or master flash will
flash twice: the first flash tests the environmental light and the second flash
captures the image. The Electronic Flash will ignore the first flash and will flash
synchronously with the second flash.
6. Automatic save function
The Electronic Flash will automatically save the current settings.
7. PC synchronous port input
The Electronic Flash synchronous port is used for connecting the flash to
the camera using a coaxial PC cable (not included). When the two pieces
are connected, the Electronic Flash can be positioned away from the
camera and doesn't need to be mounted on the camera's hot shoe bracket.
Note: the PC sync flash only accepts synchronous signal input and does
not support synchronous signal output.
8. External power supply box
The Electronic Flash uses a standard Canon external power socket. A
compatible power supply box can be purchased and connected to the
external power source socket port.

9. Power saving function

The Electronic Flash has an auto sleep function to save battery power for
n
longer use. When the Electronic Flash enters auto sleep mode, the indicator
light turns off. The POWER indicator light will flash green for 0.5 second
intervals.
In M MODE, the Electronic Flash will idle for five minutes and then will enter
n
auto sleep mode. To restart the Electronic Flash, press the TEST button or
activate the camera.
