The DWA-H Work Alerter is a simple, single circuit, self-contained program timer which is programmable to set and change signal schedules on an internal keypad. However, the DWA-H does not automatically change for Daylight Saving Time. The time must be manually adjusted for every occurrence of Daylight Saving Time.
The instructions on changing the time on the DWA-H Work Alerter is shown in the user manual:
- If the DWA-H Work Alerter has a key labeled E-Day, click here for the manual.
- If the DWA-H Work Alerter does not have a key labeled E-Day, click here for the manual.
The SonaChron DWA-S changes automatically for Daylight Saving Time.
