You can check your manual but i think the SE position of the switch is to shut off after a length of time and save the batteries. Depending on how long it's sat, it will take a short while to get ready to fire again. Therefore in some situations you might want to not use the SE position so as to be instantly ready to shoot at all times. But of course you must remember to switch it to SE if you're going to set it down for awhile :-) * **** ******* *********************************************************** * For list instructions, including unsubscribe, see: * http://www.a1.nl/phomepag/markerink/eos_list.htm ***********************************************************
