The    electronically-contralled
shutter  will not work  without
loading the battery.
The shutter will be mechanical-
ly controlled when the battery
is not  loaded and  will be re-
leased at  1/500 sec., regardless
of  the  setting on  the  shutter
speed dial.
Use one 6 volt silver oxide bat-
tery or alkaline-manganesebat-
tery.
