Setup

1. Battery Installation

The transmitter requires 2 AA batteries for operation. Ensure correct polarity when inserting the batteries.

1. Locate the battery compartment cover on the back of the unit.
2. Remove the cover.
3. Insert 2 new AA batteries, observing the polarity markings (+/-).
4. Replace the battery compartment cover securely.

2. Channel Selection

The transmitter can be set to one of three channels (1, 2, or 3) to ensure proper communication with your TFA radio weather station and to avoid interference with other wireless devices. Ensure the channel selected on the transmitter matches the channel set on your main weather station unit.

• A channel selection switch is typically located inside the battery compartment or on the back of the unit.
• Set the switch to the desired channel (1, 2, or 3).
• Refer to your main weather station's manual for instructions on how to set its corresponding channel.

3. Placement and Mounting

For accurate readings and optimal wireless transmission, consider the following placement guidelines:

• Location: Mount the transmitter in a location protected from direct precipitation (rain, snow) and direct sunlight. An ideal location is under an eaves, on a porch, or in a sheltered area.
• Mounting Options: The unit can be hung using a screw or placed on a flat surface.
• Distance: Ensure the transmitter is within the 60-meter (197 feet) range of your main weather station. Walls, metal structures, and other electronic devices can reduce the effective range.

Operating

Once batteries are installed and the channel is set, the transmitter will automatically begin sending temperature and humidity data. The integrated display will show the current readings.

• Display Readings: The LCD screen on the transmitter will show the current temperature in degrees Celsius (°C) or Fahrenheit (°F) and the relative humidity as a percentage (%).
• Wireless Transmission Indicator: A signal icon (often resembling radio waves) on the display indicates that the transmitter is actively sending data.
• Data Reception: Your main TFA weather station (models 35.1151 or 35.1153) will receive and display this data. Refer to your weather station's manual for details on viewing external sensor data.

Maintenance

Battery Replacement

Replace batteries when the display becomes dim or the main weather station indicates a low battery for the external sensor. Always replace both batteries simultaneously with new AA batteries.

Cleaning

Wipe the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the plastic casing or the display.

Environmental Considerations

While designed for outdoor use, ensure the transmitter remains protected from extreme weather conditions, especially direct water exposure and prolonged direct sunlight, which can affect its lifespan and accuracy.
