Things to think about
If you had just turned on the dse905 you must wait until the blinking stops prior to using the manual button.
if unit blinks when pressing the manual button... it could be an indication that the battery needs charging... or possibly a bad battery ... try will either a fully charged battery or just try it with the other one.
just a few possibilities
