0 comments
Ever wonder what the weather will look like in the next 12 hours or want to keep track of indoor and outdoor conditions at a glance? With the La Crosse S84107v2 Atomic Forecast Station, you’re covered. Here’s everything you need to know to get started and make the most of your new device.

Quick Setup Guide

1. Powering Up: Start by inserting 2 AA batteries in your sensor, observing the polarity. You’ll see a red LED flash when the sensor is active. Next, plug in the 5V power cord to the station. You can also insert 3 AA batteries into the station itself for time and date backup, ensuring your settings are safe even during power outages.

2. Placing Your Sensor: Once set up, find a shaded outdoor spot for your sensor. Mounting it on a north-facing wall away from direct sunlight ensures the most accurate readings. The sensor can transmit data over 330 feet in open air, though walls and metal objects may reduce this range.

3. Configuring Settings: Dive into setup mode by pressing the SET button for 3 seconds. From here, adjust settings like language, time zone, and temperature format. Use the + or - buttons to toggle through options quickly.

Key Features You’ll Love

1. Atomic Time Signal
Thanks to the WWVB atomic time signal, your station keeps time with precision, even adjusting automatically for Daylight Saving Time. For a manual time check, just press the SEARCH button.

2. Moon Phase Display
Curious about the current moon phase? Your station keeps you in sync with the lunar cycle. The moon phase updates as you set the date and year, offering a handy reminder for night sky enthusiasts.

3. Seasonal Foliage Visuals
Enjoy a fresh visual experience throughout the year, as the display changes foliage with the seasons—from spring blossoms to winter snow, it’s all pre-programmed to give you a dynamic view of the outdoors.

4. Barometric Pressure Forecasting
The weather forecast icons provide predictions based on atmospheric pressure. You’ll see clear indicators like “Sunny,” “Rain,” or even “Snow” when the outdoor temperature drops below 32°F. Trend arrows beside the word “FORECAST” reflect pressure changes in the past three hours—helpful for tracking sudden weather shifts.

5. Temperature & Humidity Tracking
The station offers both indoor and outdoor temperature/humidity readings. Trend arrows indicate changes over the past hour, updating every 15 minutes. If you want to view daily highs and lows, just press the TEMP button.

6. Custom Weather Alerts
Need a heads-up for extreme temperatures? The S84107v2 lets you set personalized alerts for both high and low values in temperature and humidity. The alert icon will flash, and the station beeps until the conditions are back to normal.

Handy Tips for Better Usage

- Backlight Adjustment: With three intensity levels (0%, 20%, and 100%), the backlight can be adjusted for day or night viewing. On battery power alone, the backlight will activate for 10 seconds at full brightness with a button press.

- Low Battery Alert: If the battery icon appears next to your temperature readings, it’s time to replace them. The station will display the last recorded data if the signal is lost, but regular checks will help avoid any interruptions.

- Sensor Search and Signal: If you lose connection with your sensor, press the SEARCH button for the station to find it. The icon will animate while searching and turn solid once the connection is reestablished.

- Factory Reset: If you encounter connectivity issues, hold the ALERTS and LIGHT buttons for 5 seconds. This factory restart will return your device to default settings, fixing most issues with a fresh start.
