The SE (Save-Energy) Function
Turn the main switch OFF (“O" mark) when flash
photography is finished to prevent unnecessary battery
consumption. The Canon Speedlite 300TL has a built-in
SE (Save-Energy) function that automatically turns off
the power when the flash is not used for approx. 5
minutes. To use this function, slide the main switch to
the "SE” position.
To use the flash after it has turned off automatically,
either press the shutter button halfway or sef the main
switch to the "I" position and then again to the "SE" posi
tion.
Interval flash photography is possible if the Command
Back 90 is used with the 300TL. Set the Command Back
90 to the interval timer or self-timer mode and set the
300TL to the "SE” position. (The flash charge will starf
one minute before the shutter release.)
