Selector Setting
The selectors can be turned clockwise and counterclockwise to
select the desired time unit, time scale, 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 malfunction could result from improper setting.
