arge volume capacitor, it can get quite a long time delay. First l/2 (556) in the oscillator mode, with a period l/f. The oscillator output is applied to the N divider network to produce an output signal having N/f cycles used to trigger other half 1/2 (556). The divider is connected to a second half (556) of the input feet, it determines the total amount of delay produced by the divider. Delay time has 30min, 1h, 2h, 4h, 4 block. If an additional series N8281 divider, such that the total amount of delay can be increased up to several days or even weeks.
