Cable Free Weather Station with Thermo-Hygrometer and Radio controlled clock MODEL: BAR938HGA USER'S MANUAL INTRODUCTION Congratulations on your purchasing of BAR938HGA Cable Free Weather Station with Thermo-Hygrometer and Radio controlled clock. RF- controlled, BAR938HGA can automatically synchronize its current time and date when it is brought within range of the radio signal generated from the U.S. Atomic Clock. BAR938HGA does weather forecasts with kinetic-movement graphic illustrations and tells indoor and outdoor temperature. It also shows the trend of changes plus the recorded maximum and minimum temperatures. Apart from temperature, BAR938HGA shows the indoor and outdoor relative humidity and rates the comfort level. It also stores in memory the maximum and minimum relative humidity readings. A remote thermo-hygro sensor is included with the unit. BAR938HGA is able to receive and display readings from up to 3 remote sensors. The built-in barometer enables BAR938HGA to display the atmospheric pressure with user-selectable altitude adjustment. A bar graph will show the pressure trend of the last 24 hours. What is more, BAR938HGA is equipped with a moon phase scanner, which lets you check the moon phase of any day between 1990 and 2019. Other features include a HiGlo backlight, daily alarm and extralarge display. No wire installation is required between the main and remote units. As BAR938HGA operates at 433MHz, it can be used in the U.S. and most places in Continental Europe. However, the Atomic Clock function of the BAR938HGA is pertinent to the U.S. only.

ABOUT RADIO RECEPTION BAR938HGA is designed to automatically synchronize its calendar clock once it is brought within range of the U.S. Atomic Clock radio signal. It will scan and adjust every full hour. When the unit is new and just out of the box, synchronization with the U.S. Atomic Clock can take up to 72 hours. When the unit is receiving radio signal, the RADIO RECEPTION indication will start to blink. A complete reception generally takes about 2 to 10 minutes, depending on the strength of the radio signal. When the reception is complete, the RADIO RECEPTION indication will stop blinking. If the signal is received, a RADIO RECEPTION indication [ ] will be shown. Otherwise, [ ] is displayed. For better reception, place the clock away from metal objects and electrical appliances to minimize interference. Should you wish to deactivate the RF controlled function, press and hold UP and DOWN button simultaneously. To reactivate the RF control function, from its deactivated status press and hold UP and DOWN simultaneously. 4. Insert the batteries strictly according to the polarities shown therein. 5.
