Setting of Selector
The selectors can be turned clockwise and counterclockwise to se-
lect the desired time unit, time range, or operating mode.
Each selector has a snap mechanism that secures the selector at a
given position. Set the selector at a position at which it is secured.
Do not set it midway between two securing positions or a malfunc-
tion could result from improper setting.
