el. Dial digits appear in the six windows around the time setting knob
according to the rated time selected by turning the rated time selec-
tor (i.e., rotary switch) located at the lower left corner of the front
panel.
The following digits will appear in the respective dial digit display
windows:

Switch Setting
The selector switches for time unit, scale, and function can be
turned in both directions, clockwise and counterclockwise. Each se-
lector switch has a snap mechanism that secures the switch at a giv-
en position. Set the switch at a position at which it is secured. Do not
set it midway between two securing positions because such prac-
tice may causes the Timer to malfunction or, in the worst case, break
down.
Accurately move and set the scale selector switch, matching the 0
position mark to a division on the scale.
!
Caution
Do not change the time unit, or operation mode while the Timer
is in operation. Otherwise, the Timer may malfunction or suffer
from damage. Be sure to turn off the power supply of the Timer
before changing the time unit, rated time or operation mode.
WARNING
