• Outdoor Sensor: Replace 3 x LR6 AA batteries when the low battery indicator appears. Ensure proper polarity during installation.

6.2 Cleaning

Wipe the main display unit and outdoor sensor with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the surfaces or electronic components. Regularly check the outdoor sensor for any debris that might obstruct the rain gauge or wind sensors.

7. Troubleshooting

• Screen Does Not Stay On: If the screen does not remain illuminated after searching for the WWVB signal, press the brightness adjustment button located on the side of the main display unit.
• No Outdoor Sensor Data: Ensure the outdoor sensor is within the 100-meter (330-foot) transmission range of the main unit and that there are no significant obstructions. Verify that the outdoor sensor has fresh batteries and that the main unit and sensor were initially paired in close proximity.
• Inaccurate Readings: Ensure the outdoor sensor is placed in an open area, away from direct heat sources, reflective surfaces, or obstructions that could affect wind or rain measurements. Allow time for the sensor to acclimate to its environment.
