MAINTENANCE AND CARE INSTRUCTIONS

• Extreme temperatures, shock or areas of unusual vibrationshould be avoided to prevent damage to the units.
• Clean the units using only a soft, damp cloth to wipe. Do not use solvents, abrasives, detergents or other strong cleaning agents. After cleaning, wipe surfaces with a dry cloth.
• Do not submerge units in water or other liquids.
• Do not subject the units to extremely severe temperatures- DO NOT PLACE UNITS INTO OVENS, FREEZERS or MICROWAVE OVENS.

NOTES

• Opening the housing of either the remote sensor or the home receiver willinvalidate your warranty. Do not attempt to repair this unit. There are no consumer serviceable parts.
• If you encounter any difficulties in setting up your wireless thermometer system, please contact Consumer Relations.
• Your new RF Thermometer is built with random security code technology. The home receiver will learn the random code of the first remote sensor and log it in as channel 1. Channel 2 and Channel 3 will be registered in the same way if additional sensors are used. The home receiver can monitor up to 3 separate sensors.
• Once a channel is registered, it will not accept any new sensors. However, registered channels can be erased by removing the batteries in the remote sensor or the home unit.
• When replacing batteries for the remote sensor - Remember to clear thecorresponding channel of the home receiver by removing the batteries or select the respective channel of the sensor by pressing the CHANNEL button on the home receiver. Hold the CHANNEL button for 3 seconds to clear the registration.
• When replacing batteries for the home receiver - Please remove the batteries of all remote sensors. Once you have replaced the home receiver batteries, re-install the batteries to the sensors according to the desired channel sequence. This will ensure that the home receiver and the remote sensors are properly synchronized.
• Press the Tx button on the back of remote sensor to verify the RF reception.
• It is recommended to test the home receiver and the remote sensor nextto each other to ensure that both are properly synchronized.
• Keep the remote sensor out of direct sunlight and rain. Do not mount on a metal surface.

About the Atomic Clock
The National Institute of Standard and Technology (NIST) in Fort Collins, Colorado broadcasts the time signal (WWVB at 60kHz AM radio signal) with an accuracy of 1 second per every 3,000 years. The signal will cover a distance up to 2,000 miles from the source. Like a typical AM radio, your Atomic Clock will not able to receive the WWVB signal in places surrounded by heavy concrete or metal panels. The reception of the time signal can be affected by mobile phones, TV, electrical appliances or other electronic interference. To get the best performance of the Atomic clock, please install the home receiver near a window and away from large metallic objects. If the unit is not working properly, change the unit position. There may be some interference at this location.

TROUBLE SHOOTING

Indoor and Outdoor temperatures do not match when placed next to each other
Each sensor is manufactured to be +/- 2 degrees in accuracy under normal conditions. So it is possible to have up to four degrees difference shown on the separate temperature sensors (one could be "+2 degree" and the other "-2 degrees". Additionally, the calibration curve is different between the two units because of the greater temperature range of the outdoor sensor.
Errors are usually noted on the extreme ends of the temperature ranges.

Base unit is not accepting remote transmissions

The units may not be properly synchronized or the batteries may need to be replaced. See "GETTING STARTED" section for detailed instructions. With the two units next to each other, attempt synchronization. Remember to always place the remote sensor within the effective transmission range and away from large metal surfaces.

What is the recommended battery type?

Your unit will come with 4 "AA" alkaline batteries (2 "AA" batteries required for each unit). We recommend using only alkaline batteries for replacements.

Where can I mount the remote sensor?

To get accurate readings and to prolong the life of your sensor, we recommend that you mount it out of direct sunlight and rain. Fog and mist will not affect the sensor, but large volumes of soaking rain may. To guard against this, we recommend that you mount it under the eve of your house, your garage or any other suitable place that will keep it out of direct sun and rain.

Outdoor Temperature Reading shows "- - "

This is usually an indication that the channel selector (located in the top left corner of the home receiver) is set incorrectly to receive the signal from the remote sensor. If you have only one remote sensor, ensure that the channel selector is set to "1". To change the channel, press the "channel" button located on the front of the home receiver.
The home receiver may also be "scrolling" - looking for sensor readings from more than one remote sensor. This home receiver can support up to three remote sensors (only one is included). If it is looking for more than one remote sensor, a " " icon will appear below the channel designator. Again, to select a reading from just one remote sensor, press the "channel" button to remove the scroll icon and ensure that the channel selected now reads "1".

The unit is "locked" - I can't perform unit functions

When this occurs, the unit maybe in "forced synchronization" mode. If the radio antenna icon shows "waves" projecting from it, the unit is attempting to synchronize with the atomic clock frequency. To override, simply press the " - " button on the back of the unit. You will now be able to perform all other functions.

The weather forecast does not match current outdoor conditions

The forecast projects weather conditions 8-12 hours into the future. It does not reflect current conditions.
To ensure accurate weather forecast, it may be necessary to manually enter existing conditions (see "Input Existing Weather Conditions").
