DISPLAY UNIT PLACEMENT

Place the display unit in a dry area free of dirt and dust.
The display unit stands upright for tabletop/countertop use.

Important Placement Guidelines

To ensure accurate temperature measurement, place units out of direct sunlight and away from any heat sources or vents.
The display unit and outdoor sensor must be within 200ft (60m) of each other.
To maximize wireless range, place units away from large metallic items, thick walls, metal surfaces, or other objects that may limit wireless communication.
To prevent wireless interference, place both units at least 3ft (1 m) away from electronic devices (TV, computer, microwave, radio, etc.

OUTDOOR SENSOR PLACEMENT

The sensor must be placed outside to observe outdoor conditions. It is water resistant and designed for general outdoor use, however, to prevent damage place the sensor in an area that is protected from the direct weather elements and direct sunshine. The best location is 4 to 8 feet above the ground with permanent shade and plenty of fresh air to circulate the sensor.
The display unit and outdoor sensor must be within 100 feet of each other.
To maximize the wireless range, place units away from large metallic items, thick walls, metal surfaces or other objects that may limit wireless communications.
To prevent wireless interferences, place both units at least 3 feet away from electronic devices (EX: TV, computer, microwave etc.)

Outdoor Sensor Function

Once the display unit has been set up and the channel synchronized with the outdoor sensor, the display unit will begin the registration process. It can take up to 3 minutes to complete the registration, where the display unit will search for an RF (Radio Frequency) signal from the outdoor sensor. The outdoor sensor signal strength will show the connection strength to the outdoor sensor. If there are no bars or if bars are not showing at their maximum strength (4 bars) try placing the outdoor sensor or display unit elsewhere for better connection. The temperature and humidity data are updated every minute if a change is detected.
If the RF Signal is lost and not reconnected, the outdoor temperature and humidity level will begin to flash after 1 hour of lost connection. If no connection was found after 2 hours only a dotted line ‘ – -. – ’ will be displayed in place of the temperature and humidity level.
To manually restart the RF registration, press and hold the “CH” button for 3 seconds. The display unit will now search for the RF signal for the next 3 minutes.
