In order to establish proper communication between the display and outdoor transmitter it is important that they be set up as follows:

1. Bring both units inside and have the units 3-5 feet apart with nothing in-between them.
2. Remove the batteries from both units.
3. Press one of the buttons on the display at least 20 times to clear all memory. Verify that the display is blank before proceeding.
4. Using a good quality alkaline battery place them back into the remote sensor; making sure they are installed according to the diagrams in the battery compartment. Next, taking care not to press any buttons, reinstall the batteries in the display according to the diagram in the battery compartment.
5. Do not press any buttons for at least 15 minutes after installing the batteries. (Let them establish a good connection.)
6. An outdoor temperature should be showing on your display. You can now put your outdoor sensor back outside.

In order to get an accurate reading and to prolong the life of your sensor we recommend that you have it in a sheltered area out of the sun and direct rain. Fog and Mist will not affect the sensor, but a soaking in water may. If your sensor becomes soaked, removed the batteries and allow it to try overnight; then restart the station (see section 1A). You can mount it outside under an eve of your house or any other suitable place that will keep it out of the sun and rain. Do not wrap the sensor in plastic or seal it in a plastic bag.

The maximum transmission range is 80 feet in a straight line (line of sight). Exterior walls and obstructions will reduce transmission range by as much as 25-30 feet while interior walls and similar obstructions will reduce transmission range by as much as 15-20 feet. (An obstruction would include anything that is between the line of sight like a roof, walls, floors, ceilings, trees, etc.) For best signal reception the transmission range should be greater than the line of sight distance between the transmitter and receiver. Certain building materials as well as electrical interference may also affect signal reception.

Each temperature sensor is manufactured to be accurate to within 1 degree plus or minus and under normal conditions, so two sensors could be as much as 2 degrees different. However, the difference can be exaggerated further because the sensors are designed for different working environments. The indoor sensor is less responsive to ambient air currents because of the shielding effect of the display's case. In addition, the case can act as a heat sink to absorb and store heat from external sources (i.e. handling of the case or radiant heat). Also, the much greater at the extreme ends of a range, making it harder to compare different ranges with different curves. Under non-laboratory conditions, it is difficult to compensate for the above factors and obtain an accurate comparison.

If either MIN or MAX is displayed above either temperature, press and release the MIN & MAX button until neither MIN nor MAX is showing on the display.

Press and hold the MIN & MAX button for 5 seconds. The temperatures will then reset to the current temperatures.

Check the polarity on your batteries to make sure they are installed according to the diagrams in the battery compartment. Also make sure that you are using a new good quality alkaline battery.
