(H) Flasher (Repeat Cycle Starting with Pulse or Pause)
The repeat cycle timer permits different settings for on and off times. The following operating modes are possible:
 Oscillating mode; repeat cycle starts with voltage applied at A1 and B1, and continues to repeat until voltage is off.
 One cycle mode; started by energizing B1 with voltage on A1 and A2.
 Output starts with pulse or pause (switch ⊗ Up or Down).
