Setup

Battery Installation

For optimal performance, use high-quality alkaline batteries. Lithium batteries are recommended for outdoor sensors in environments where temperatures can drop below -4F (-20C).

1. Wireless Outdoor Sensor: Remove the battery compartment cover. Insert 2 x AA batteries, observing the polarity (+/-) diagram. Replace the cover.
2. Digital Display Unit: Remove the battery compartment cover. Insert 2 x AA batteries, observing the polarity (+/-) diagram. Replace the cover.
3. Allow both units to power on and establish a connection. This may take a few minutes.

Sensor Placement

Proper placement of the wireless sensor is crucial for accurate temperature readings and optimal signal transmission.

• Place the sensor in a location that is out of direct sunlight and away from heat sources (e.g., exhaust vents, windows).
• Mount the sensor securely using the integrated hang hole or a string.
• Ensure the sensor is within 100 feet (30 meters) of the digital display unit. Walls and other obstructions can reduce signal range.
• Avoid placing the sensor near large metal objects or heavy electrical appliances that could interfere with the wireless signal.

Intelli-Time Clock

The Intelli-Time clock is pre-programmed with the correct time and date. It automatically updates for Daylight Saving Time. Simply install the batteries, and the clock will set itself. No manual adjustment is typically required.

Self-Calibrating Forecasting

The weather forecaster uses a unique self-calibrating algorithm that analyzes changes in pressure over a period of 14 days to determine your altitude and provide the most accurate forecast for your specific location. This learning mode ensures the forecast becomes more precise over time.

Maintenance

• Cleaning: Clean the display unit and sensor with a soft, damp cloth. Do not use abrasive cleaners or chemicals that could damage the plastic components.
• Battery Replacement: Replace batteries in both the display unit and the outdoor sensor approximately every 12-24 months, or when the low battery indicator appears on the display. Always replace all batteries at the same time.
• Sensor Protection: While the outdoor sensor is weather-resistant, avoid submerging it in water or exposing it to extreme conditions beyond its specified operating range.
