I put new batteries into my Taylor WEC 1502 and both indoor and outdoor temperature works but I can not get the time to set right.

To disable the alarm function on your Taylor weather station type WEC-1502, follow these steps:

1. Press and hold the "ALARM" button on the top of the unit until the alarm icon disappears from the display.
2. Release the "ALARM" button.
3. Press the "MODE" button on the top of the unit until the display shows the "CLOCK" mode.
4. Press and hold the "ALARM" button again until the alarm icon disappears from the display.
5. Release the "ALARM" button.

Your Taylor weather station should now be set without the alarm function.

Question edited to add make name, which also happens to be mine!

The easiest way is just to remove the batteries for 20 seconds. The manual as not good because it is made in China.
