Recycling Time and Flash Count (with size-AA alkaline batteries)
" on new
• Quick flash enables a flash to be fired before flash-ready (p.1 0).
-- • Using size-AA batteries other than the alkaline type may cause improper
battery contact due to the irregular shape of the battery contacts.
• If you change the batteries after firing many flashes continuously, be
aware that the batteries might be hot.
