Frequently Asked Questions - 404-1235UA-SS LA CROSSE TECHNOLOGY
How do I set the time on my La Crosse Technology 404-1235UA-SS clock?
Press and hold the SET button for 3 seconds to enter manual time setting. Use the +/- buttons to adjust hours, minutes, year, month, and date. Press SET again to confirm each step. The clock will automatically search for the atomic time signal after setup.
Why is my clock not receiving the atomic time signal?
Place the clock near a window facing Colorado (USA) at night. Avoid interference from electronics. Press and hold the RECEIVE button to manually force a signal search. It may take up to 10 minutes to sync.
How do I set the alarm?
Press the ALARM button to enter alarm mode. Use +/- to set the alarm time. Press ALARM again to save and activate. The alarm icon will appear. To silence, press any button or the SNOOZE button for a 10-minute snooze.
Can I use rechargeable batteries in this clock?
Yes, you can use rechargeable AA batteries. However, battery life may be shorter. Ensure they are fully charged. The clock will indicate low battery when needed.
How do I mount the clock on a wall?
Remove the desk stand. Use the built-in keyhole slot on the back to hang on a screw. Ensure the screw head is appropriate for the slot. Use a level to keep it straight.
What does the temperature reading show?
The clock displays indoor temperature only unless you add a remote sensor (model LTH8). With a sensor, it can show outdoor temperature and humidity. Refer to the manual for pairing instructions.
How do I change between 12-hour and 24-hour time format?
Press and hold the SET button until the hour digits flash. Press the + button to toggle between 12H and 24H. Press SET to confirm and exit.
Why is the display showing 'LL' or 'HH'?
'LL' means the temperature is below the measurable range (below 32°F). 'HH' means it exceeds the maximum (above 122°F). Move the clock to a more suitable location and allow it to adjust.
How do I replace the batteries?
Slide the battery cover downward on the back of the clock. Remove old batteries and insert two new AA batteries with correct polarity (+/-). Replace the cover. The clock will reset and begin searching for an atomic signal.
Can I disable the atomic time synchronization?
Yes, press and hold the RECEIVE button for 5 seconds to turn off atomic sync. The clock will then function as a standard quartz clock. Repeat to turn sync back on.
