Note that the shutter speed is not being changed. Then, I would take the EV number from the meter and transfer it to the camera by depressing the the little lever at the bottom of the lens an moving the indicator to the setting indicated on the meter. On my IIc, I would first set a shutter speed by moving the ring to the desired setting.

I don't think I've ever read a good explanation of the EV system, and the Retinette Guide is no exception.
