MAINTENANCE AND CARE INSTRUCTIONS • Extreme temperatures, shock or areas of unusual vibration should 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 UNITS. NOTE: Opening the housing (other than the battery compartment) of either the Remote Sensor or the Home Unit will invalidate your warranty. Do not attempt to repair this unit - There are no consumer serviceable parts. TROUBLE SHOOTING Indoor and Outdoor temperatures do not match when placed next to each other - Each sensor is manufactured to be +/- 1 degree in accuracy under normal conditions. So it is possible to have up to two degrees difference shown on the separate temperature sensors (one could be "+1 degree" and the other "-1 degree". 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 "SETTING UP THE WIRELESS THERMOMETER" section beginning on page 2 of the instructions 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 units will come with 4 "AA" alkaline batteries (2 "AA" batteries required for each unit). We recommend using only alkaline batteries for replacements. 8 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. Modifications not authorized by the manufacturer may void users authority to operate this device.
