TEMPERATURE/HUMIDITY SENSORS
• Mounting under an eave or deck rail works well.
• Mount the remote sensor on the North side where to prevent sun from
causing incorrect readings
• Be sure the outdoor sensor is mounted vertically to drain moisture.
• Mount at least 6 feet in the air for a strong RF (radio frequency) signal.
• To prevent wireless interference, place units at least 3 ft (0.9 m) away from
electronic devices (TV, computer, microwave, radio, etc.)
• To maximize atomic signal reception, place the weather station away from large
metallic items, thick walls, metal surfaces, or other objects that may limit
radio communication.
• The maximum wireless transmission range must be within 300 feet (100m)
in open air, not including walls and floors.
• In Normal display, press and release to interchange the reading display
for the outdoor temperature/humidity sensors.
• There are CH1, CH2 CH3 or cycle display.
• In cycle display mode, the outdoor temperature/humidity reading will be
switched every 3s.
