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.)
