Press the button on the right labeled "start/stop" and at the same time press the button on the left labeled "split/reset." Hold both of these buttons down to scroll through the functions.
Release both buttons when the "Alarm Set" display is reached. This will show the time that the alarm is set for, even if the alarm is not active.
Press and hold the "Mode" button, which will remove the bars shown under the days of the week. Wait until all of the bars have been removed. This will stop hourly chiming.
