HOW DO I CHANGE BATTERIES IN MY SENSORS WITHOUT LOSING DATA?

We designed this station for convenience, so that a simple change of batteries does not lose
data or require you to power down your station.
• If you have a low battery icon on your station, you need to replace the batteries in the
sensor or in the station as indicated.
• Simply install fresh
and your station will search for your sensors.
• When changing the batteries in the station, continue using the power cord. After replacing
the batteries, no other action is needed. The batteries in the station only maintain time/date
in the event of a power outage.
BAR CODE: WHAT ARE THE BARCODES AND ID NUMBERS
• Did you know that your sensors will "lock" into your station?
• This ensures that the sensor readings are from your sensor and not a neighbors'.
• When you press and release your SENSOR button you will see your station ID, your
thermo-hygro sensor ID, and your wind speed sensor ID.
• The sensor ID on the station should match your first six numbers on the barcode of that
sensor.
• These sensors will remain locked to your station until you manually delete them.
• The barcodes are also important identifiers for the La Crosse View™ app if you choose to
connect.
In the rare event you need to replace your sensor, you will first need to delete the old sensor ID
from your station.
1. Remove batteries from your old sensor.
2. Press and release the SENSOR button to view your sensor ID number.
3. While viewing your sensor ID, hold the MINUS button for 5 seconds to delete your old
sensor ID. Dashes will show for the ID number.
4. Your station will automatically begin searching for the new sensor.
5. Install batteries in your new sensor and allow up to three minutes for your new sensor
readings and ID to appear on your station.

FACTORY RESET: HOW DO I FACTORY RESET MY STATION?

• A factory reset will delete all sensor ID numbers and if connected, remove all Wi-Fi
connections.
• Basically this is a great way to return your station to "out of the box" condition.
• This is more effective than removing all power for clearing out the station.
