hi
i have just recived a 540EZ i bought off ebay , there are no instructions with it, before i blow my camera or do something silly i would appreciate any help setting this up i have a 20D and want to use this in M mode many thanks for any help

hit the mode button until it goes into M mode, then to change the power you hit the Sel/Set button and the the power will blink, at that time you can use the + and - buttons to turn up or down the power.

You can dl manual here:
