1. Choose a range from the timing table by setting the A and B selectors to the desired position. For example,

setting the A and B selectors to the positions A: ↓ and B: ↓ selects a range of time between 64 and 640 minutes

(1 to 10 hours).

2. Set the red selector to multiply the minimum value of the chosen range by the value at which it is pointing. If the

selector points to position 2: 2 * 64 = 128 minutes (approximately 2 hours). If the selector points to position

4: 4 * 64 = 256 minutes (approximately 4 hours).
