Using this momentary action switch will cause all emergency lights to illuminate for one minute. Nice gimmick if you want to check the exterior emergency lights - no need to go inside and switch them on.
Thanks folks....I check it out last night at work after searching through some Docs.The reason the Freighters dont have the switch is because there are no escape doors apart from the Windows & the Entry door on the B752PCF.Hence same was deactivated.
I may not win often, but I damn well never lose!!!
