SETTING THE CLOCK TIME
Rotate the program dial gradually clockwise until the time of day on the outer
dial is nearly aligned with the triangle marker at the 2 o’clock position. Then set
time to the minute by rotating minute hand clockwise until the time of day (and
AM or PM) on the outer dial is aligned with the triangle marker on the inner dial.
NOTICE! Do not rotate the dial or minute hand counter-clockwise. Doing
so will damage the timer.
SETTING ON/OFF TIMES
Move the white tab (tripper) on the outer dial outward at the start of the desired
ON period. Move each adjacent tab outward until the desired OFF time is
reached.
