LCD Indoor/Outdoor (630-0867) Preparation Faxback Doc. # 7946 Thermometer/Hygrometer INSTALLING/REPLACING THE BATTERY Your thermometer/hygrometer requires two AA batteries (not supplied) for operation. For the longest life and best performance, we recommend alkaline batteries, such as Radio Shack Cat. No. 23-557. Follow these steps to install or replace the batteries. 1. Lift and pull up the top center edge of the battery compartment cover, then remove the cover. 2. Remove and discard any old batteries. 3. Place two fresh AA batteries in the compartment as indicated by the polarity symbols (+ and -) marked inside the compartment. As soon as you install the batteries, ---f188 appears on the upper display, and ---F appears on the lower display. After a few seconds, the temperature that the thermometer/hygrometer senses through the attached outdoor sensor appears on the lower display. Then the indoor temperature appears on the upper display. After about 10 seconds, the indoor relative humidity appears on the upper display. 4. Select the temperature scale by setting degree C/degree F in the battery compartment to degrees C for Celsius, or degrees F for Fahrenheit. Note: You can change the temperature scale at any time. 5. Replace the cover. Notes: Fresh alkaline batteries last for about 1 year. If the displays appear weak or if the thermometer/hygrometer does not work properly, replace the batteries. Use only fresh batteries of the required size and type. Do not mix old and new batteries. Cautions: Never leave dead or weak batteries in the thermometer/ hygrometer. Dispose of batteries properly; do not bury or burn them. CHOOSING MOUNTING LOCATIONS Choose locations for mounting the thermometer/hygrometer and the attached outdoor sensor that are within 10 feet of each other and that will let you easily route the outdoor sensor outside. For the best results, mount the thermometer/hygrometer and outdoor sensor on drywall or wood surfaces. Avoid mounting either on ceramic tile or metal surfaces. The most common way to route the outdoor sensor outside is through a corner or depression in a window sill or door edge. You can also use a pass-through tube (Such as Cat. No. 15-1200) to route the outdoor sensor through a wall. Cautions: The outdoor sensor is permanently attached to the thermometer/ hygrometer. Do not try to remove it. Avoid routing the outdoor sensor's cord where it could be pinched or cut. Note: Keep the thermometer/hygrometer and outdoor sensor away from artificial sources of heat or cold such as stoves, heating and air conditioning vents, radiators, and direct sunlight. MOUNTING THE THERMOMETER/HYGROMETER You need one flathead or Phillips wood screw (not supplied) to mount the thermometer/hygrometer on a wall. Make sure the screw head fits in the keyhole slot on the back of the thermometer/hygrometer. 1. Mark the position of the screw hole. 2. In the marked location, drill a hole slightly smaller than the wood screw. Caution: Be careful not to drill into my objects behind the wall. 3. Using a flathead or Phillips screwdriver, drive the screw into the wall, letting the head extend 1/8-inch from the wall. 4. Align the keyhole slot on the back of the thermometer/hygrometer with the screw head in the wall, then carefully push the thermometer/ hygrometer onto the screw head and slide it down into place. MOUNTING THE OUTDOOR SENSOR You need one nail, wood screw, or masonry screw (not supplied) to mount the outdoor sensor. Make sure the nail or screw head is larger than the small loop on the wire bracket attached to the outdoor sensor. 1. Mark the position of the screw hole. 2. In the marked location, drill a hole slightly smaller than the nail or screw. Caution: Be careful not to drill into any objects behind the wall. 3. Slide the wire bracket off the outdoor sensor. 4. Push the nail or screw's tip through the small loop on the wire bracket, then drive the nail or screw into the wall. 5. Slide the outdoor sensor onto the wire bracket. (LB/all-11/30/94)
