How do I stop my Canon Speedlite (430exii) from going to sleep? (auto power off)

Question

I want to use my Speedlite flash as my main flash off-camera and fire it remotely (with cactus V2 triggers) but I find it really annoying when the camera just goes to sleep and I have to walk over and wake it up again.

Is there any way to disable this power save feature?

Answer 1

The "Auto power off" feature can be toggled as one of the unit's "custom features". You need to set feature number 1 to have the value "1".

To set the custom features:

1. Press the "C.Fn" button for 2 sec. or more so that "C.Fn" is displayed on screen.
2. Select the Custom Function No.
   • Press the + button to select the Custom Function number ("01").
3. Change the setting.
   • Press the "sel" button.
   • The setting number will blink.
   • Press the + button to set the desired number ("1"), then press the "sel" button.
   • After you set the Custom Function and press the "MODE" button, the camera will be ready to shoot.
