Lathem DWA 18-1 Bell Ringer: Daylight Savings Time Adjustment Instructions

The DWA 18-1 Bell Ringer by Lathem does not automatically change for Daylight Saving Time. You must manually adjust the time each time Daylight Savings Time rolls around. Lathem's DWA 18-1 has been discontinued for quite some time.

To adjust your Lathem DWA 18-1 for Daylight Savings Time:

  1. Pull the PULL TO ACCESS KEYPAD button to separate the keypad panel from the door.
  2. Press the DAY of the week.
  3. Press the WK key.
  4. Press AM or PM for morning or afternoon.
  5. Enter the time to adjust for Daylight Savings Time.
  6. (Press the CLR key to make any corrections.)
  7. Press the CLK key to start the clock.

After the CLK key is pressed, your Lathem DWA 18-1 will be successfully adjusted for Daylight Savings Time.
