Nikon EL2 - Manual (Page 19)

the lock depressed, rotate the dial counterclockwise off
of the “A" position; when the dial is aligned with white
settings of from 2 to 1000, the actual shutter speed is a
fractional value of from 1/2 second to 1/1000 second,
while the remaining settings indicate the actual values
of from 8 seconds to 1 second. The red "125” setting
indicates that the 1/125 second shutter speed is the
fastest speed providing X synchronization for use with
electronic flash units. At the “B” setting, the shutter
remains open as long as the shutter-release button is
depressed. If you have forgotten to install the battery,
the shutter gives a mechanically fixed speed of 1/90
second regardless of the dial position. (See "Flash
Synchronization” on page 38 for additional infor­
mation on flash photography.)
Note: The Nikon EL2 consumes battery power at all shutter-
speed dial settings and, thus, is subject to the same limitations
on battery life (i.e., approx. 10 hours continuous operation
with fresh batteries) even at the "B” setting.
