How To Set The Time On A Lacrosse Weather Station – Lacrosse Display Time Adjustment

by

Learning how to set the time on a LaCrosse weather station is a fundamental step to ensuring all your weather data is logged correctly. To set the time on a LaCrosse station, you’ll navigate the console’s settings menu using its buttons. This guide will walk you through the process for various models, troubleshoot common issues, and explain why accurate timekeeping is so important for your station’s function.

How To Set The Time On A Lacrosse Weather Station

The core process for setting the time is similar across most LaCrosse consoles. You will be using the buttons on the front or top of the unit to enter a settings menu. The exact label for the button might vary; it’s often called “SET,” “MENU,” or “CONFIG.” Have your console’s manual handy if possible, as it provides model-specific diagrams.

General Step-By-Step Instructions

Follow these general steps. They apply to popular models like the LaCrosse Technology C85845, T83646, and many others in the S-Series and Wireless Pro series.

  1. Locate and press the “SET,” “MENU,” or “CONFIG” button on your console. Hold it for 2-3 seconds until the display changes, often showing a blinking number.
  2. Use the “+” or “UP” and “-” or “DOWN” buttons to adjust the blinking value. This is usually the hour first.
  3. Press “SET” or “MENU” again to move the blinking cursor to the minutes.
  4. Adjust the minutes using the same up/down buttons.
  5. Continue pressing “SET” to cycle through other settings you may need to adjust, such as 12/24-hour format, year, date, and time zone.
  6. After setting the last value (often the time zone), press and hold the “SET” or “MENU” button again to save and exit the settings mode. The console should return to the normal weather display.

Some newer models with more advanced displays may have a dedicated “CLOCK SET” option within a main menu. The princple of using the buttons to navigate and adjust remains the same.

Setting The Time On Specific LaCrosse Models

While the general method is consistent, here are some notes for specific model families.

LaCrosse Technology Wireless Weather Stations (S-Series)

Models like the S82907 or S84870 typically have a “SET” button. Press and hold it until the time zone (like “P-8” for Pacific) blinks. Use the up/down arrows to set your time zone offset from GMT. Press “SET” to confirm and move to the hour, then minutes, then year/month/date. Remember to set the correct year, as this affects the almanac and moon phase.

LaCrosse Color Weather Stations

Color models, such as the C85845 or C84612, often feature a “MENU” button. A menu will appear on the screen. Use the arrow buttons to highlight “Time Set” or “Clock Settings” and press “MENU” again to select it. You will then follow a similar blinking sequence to set all time and date parameters. These models sometimes offer an option for Daylight Saving Time (DST) auto-adjustment, which we recommend enabling.

LaCrosse Atomic Clock Models

If you have an atomic clock model, the process is different. These units are designed to set themselves automatically by receiving the WWVB radio signal from Fort Collins, Colorado. You usually only need to select your time zone.

  1. Press and hold the “SET” button until the time zone blinks.
  2. Use the arrows to choose your correct time zone (e.g., EST, CST, MST, PST).
  3. Press “SET” to confirm.
  4. The console will then attempt to receive the atomic signal, often overnight. A “RCVD” indicator will appear when successful.

Common Issues And Troubleshooting

Sometimes, setting the time doesn’t go smoothly. Here are solutions to frequent problems.

The Time Won’t Save

If your settings revert when you exit the menu, you may not be exiting correctly. Ensure you are pressing and holding the “SET” or “MENU” button for a full 2-3 seconds after the last adjustment until the normal screen returns. Simply tapping it might just cycle to the next setting without saving.

The Buttons Are Not Responding

First, check that the console’s battery backup is fresh. Weak batteries can cause the buttons to become unresponsive or the unit to behave erratically. Replace the AA or AAA batteries in the back of the console. Also, ensure you are pressing the buttons firmly enough.

Time Is Incorrect After A Power Outage

Many LaCrosse stations rely on battery backup to maintain time during a brief power loss. If the power is out for an extended period and the backup batteries are dead, the time will reset. You will need to set it again manually following the steps above. Consider replacing the backup batteries yearly as preventative maintenance.

Atomic Clock Won’t Synchronize

If your atomic model isn’t showing “RCVD” and the time is wrong, try these steps:

  • Place the console near a window, away from electronics, for better signal reception.
  • Initiate a manual search for the signal via the menu (often called “Search for Signal” or “Manual Sync”).
  • Be patient. Reception is best at night and can take several days.
  • Check that the correct time zone is selected; an wrong zone will give you the wrong local time even with a good signal.

Why Accurate Time Setting Is Crucial

Setting the time correctly is not just about convenience. It is essential for the core features of your weather station.

  • Data Logging: High/low records, rainfall totals, and storm alerts are all time-stamped. An incorrect clock makes this historical data unreliable.
  • Forecast Accuracy: The station’s forecast algorithm uses pressure trends over time. If the time is skewed, it may misinterpret these trends.
  • Alarms and Alerts: Time-based alarms for temperature or humidity will not trigger at the right moment if the clock is off.
  • Sensor Synchronization: The console coordinates data from multiple outdoor sensors. Precise timing helps ensure all readings are aligned correctly.

Additional Time-Related Settings To Configure

Once the basic time is set, check these other settings to fully optimize your station.

Daylight Saving Time (DST)

Most modern LaCrosse models have an auto-DST option. We strongly recomend enabling this in the settings menu. It will automatically spring forward and fall back, so you don’t have to manually adjust the time twice a year. If your model lacks this, you’ll need to remember to adjust the hour manually when DST changes occur.

12-Hour vs. 24-Hour Format

You can usually choose between a 12-hour format (AM/PM) or a 24-hour military format. This is a personal preference and is typically found within the same time-setting menu sequence.

Time Zone Offset

This is critical. Even if you set the hour and minute correctly, selecting the wrong time zone offset (e.g., choosing Central when you live in Eastern) will make your station’s time wrong relative to atomic sync or your own expectations. Double-check this setting.

Maintaining Correct Time Long-Term

To avoid frequent time resets, follow these simple maintenance tips.

  1. Use high-quality alkaline or lithium batteries for the console’s backup power.
  2. Plug the console’s AC adapter into a surge protector to guard against power spikes that can corrupt its memory.
  3. For atomic models, periodically check for the “RCVD” indicator. If it disappears for more than a few days, reposition the console and initiate a manual signal search.
  4. Review the time and date every month or so to ensure it hasn’t drifted, especially on non-atomic models.

Frequently Asked Questions

How Do I Change The Time On My LaCrosse Weather Station?

You change the time by entering the settings menu. Press and hold the “SET” or “MENU” button on your console. Then, use the arrow buttons to adjust the blinking hour, minute, and other date values. Finally, hold the “SET” button again to save and exit.

Why Is The Time Wrong On My LaCrosse Atomic Clock?

An atomic clock showing the wrong time usually means it hasn’t successfully received the radio signal, or the time zone is set incorrectly. Ensure the console is placed for optimal reception (near a window, away from electronics) and verify the time zone setting in the menu.

How Do I Set The Time Zone On A LaCrosse Weather Station?

Enter the settings mode by holding the “SET” button. The first setting that often blinks is the time zone offset (like “P-8” or “EST”). Use the up/down buttons to select your correct zone, then press “SET” to move to the next setting.

What Should I Do If My LaCrosse Console Buttons Don’t Work?

First, replace the console’s backup batteries. Weak power is the most common cause of unresponsive buttons. If that doesn’t help, try unplugging the AC adapter, removing all batteries for two minutes, and then reinstalling everything to perform a hard reset.

Does My LaCrosse Station Adjust For Daylight Saving Time Automatically?

Many newer LaCrosse models do have an auto-Daylight Saving Time feature. You can check and enable this in the settings menu, often listed as “DST ON/OFF” or “Daylight Savings.” Consult your manual to confirm if your specific model supports this convenient funtion.
