CABLE FREE WEATHER STATION MODEL: WMR112A USER'S MANUAL THE THERMO-HYGROMETER The thermo-hygrometer measures outdoor temperature and humidity. It uses two (2) UM-3 or "AA" size batteries. Follow these steps to install / replace batteries: 1. Remove the screws on the battery compartment. RESET SECTION 1 INTRODUCTION Congratulations on your purchasing the WMR112A Cable Free Weather Station. An all-purpose easy-to-use system, the WMR112A lets you monitor the following weather elements: - Air temperature - Relative humidity - Barometric pressure The WMR112A is also equipped with: - RF calendar clock with daily alarm - Weather forecast within 32 to 48 km (20- to 30-mile) radius - Weather alarms - Memory for maximum and minimum readings - Touch-screen plus key button operation THE BARO-THERMO-HYGROMETER PACKAGE The original WMR112A includes the following: - Main unit (WMR112A) - Baro-thermo-hygrometer (BTHR968) - Thermo-hygrometer (THGR268) - 12V AC adapter The WMR112A can support up to seven different remote instruments. You can connect up to three optional thermo or thermo-hygro sensors to the system. Optional items include: - Anemometer (WGR968) - Rain gauge (RGR968) - Thermo sensor (THR238/THC268) - Outdoor Thermo-hygrometer(THGR968) Contact an authorized dealer for optional items. 2. Mount the unit where you want to monitor the readings. Or you can make use of its table stand to place it on a flat surface. The baro-thermo-hygrometer measures the atmospheric pressure, temperature and humidity. The sensor uses four UM4 or "AAA"-sized batteries. To install it, 1. Insert alkaline batteries accordingly. 2. Assign a channel to the sensor by changing the channel switch in the battery compartment of the remote sensor. 3. Select the unit of measurement for the temperature display on the degrees C and degrees F slide switch 4. Insert the batteries strictly according to the polarities shown therein. 5. Press the [RESET] button. 6. Replace the battery compartment door and secure its screws. SECTION 2 INSTALLATION THE MAIN UNIT The main unit gives you all the readings and controls. It should be placed indoors. The main unit is powered up by the 12V AC adapter. To install it, 1. Position the main unit and other units within effective range (300 feet). 2. Insert four UM4 or "AAA"-sized alkaline batteries for backup purpose. 1 The WMR112A operates at 433MHz. No wire installation is required among units. The WMR112A has an effective range of 300 feet in an open area. Position the units within the range and be sure the transmission path is clear of interference and obstacles. Note: The thermo-hygrometer should be installed outdoors and in locations that best measure the weather elements which the instruments are designed for. As for the baro-thermo-hygrometer, it must be installed indoors. If you have any optional thermo or thermo-hygro sensors, they can be installed outdoors or indoors.

The main unit will start searching for signals for about four minutes. Upon successful reception, the readings will be displayed. The main unit will update the readings at regular intervals. LOW-BATTERY WARNING ] for the main unit, baroThere are low-battery indicators [ thermo-hygrometer, thermo-hygrometer and optional remote thermo and thermo-hygro sensors. Replace the batteries when the respective indicators light up. Note: The readings collected from the thermo-hygrometer and any optional remote thermo and thermo-hygro sensors share the same display window. The "OUT" and remote channel will share the same low-battery indicator.When the battery level of the thermohygrometer or the optional remote sensors is low, the lowbattery indicator will blink. To locate the channel in question, press the window to scan through all available devices. The lowbattery indicator will stop blinking if the battery level is low for that one.

It automatically synchronizes its current time and date when it is brought within range of the radio signal generated from U.S. Atomic Clock. You can also set the calendar clock manually. To do so, 1. Press the RF calendar clock and alarm window. 2. Press and hold [ ] to disable the radio reception function. ABOUT RADIO CONTROLLED CLOCK RECEPTION Whenever the WMR112A is brought within range of the radio signal with its radio reception function activated, it will search for the clock signal at a predefined time on each day while the manual calendar clock settings will be overridden. When the unit is new and just out of the box, synchronization with the U.S.atomic clock can take upto 72 hours. The unit will receive the mostdependable and interference free signal automatically between Midnightand 4 AM. While receiving the signal the radio reception indicator will blink. A complete reception generally takes 2 to 10 minutes, depending on the strength of the radio signal. The indicator will stop blinking when the reception is complete. The status of reception will be shown: For best signal reception, place the unit away from other equipment that emit RF or microwave signals such as TV's, radios, PC'sor microwave ovens. Other causes for signal interference include electrical power transmission towers, steel reinfoced concrete construction, and/or metal siding. After receiving the initial signal, updates are accomplished with greaterease. Even though there are areas that may have more difficulty in receiving a signal, the RF clock contains very accurate quartz movement and will retain precise time even if a signal is missed on a rare occasion. To disable the radio reception function: 1. Press the RF calendar clock and alarm window. ] to disable the function. The radio reception 2. Press and hold [ indicator will disappear.
