300 - challenge - first mistakes

My battery went down during the first round yesterday - so I switched to (powerless mode) with the hope that I can continue do pictures like that, just few hours later I remembered that in this mode the speed is stuck at 1/400 - so the shots in the dark will be just black without any white :)
Will look for battery today during lunch break.

It looks something like that - so it is not easy to find.

here is what I have found in the manual:

If you were to suddenly find yourself with a

dead battery in the midst of a photographic

session, switch over to the emergency shutter

operation mode. In order to do so, push the

Collar Stop lever “D” toward the camera body

and while holding it there align the white dot of

the Release Button Collar with the orange dot

“E” on the camera body. The shutter will now

operate (even without a battery) at approximately

1/400 sec., regardless of the setting of

the Shutter Speed Dial.

Because electricity is not being used in the

emergency shutter operation mode, the

Monitor Lamps in the viewfinder will not

illuminate. Moreover, even if the Dark Slide is

not withdrawn, the shutter can still be

released, so exercise care.
