INTRODUCTION

Thank you for selecting the BAR938HG Top Weather Station. BAR938HG is an all-in-one clock and weather device. RF- controlled, it can automatically synchronize its current time and date when it is brought within an approximate 1500km radius of the radio signal generated from Frankfurt, Germany (DCF77). BAR938HG 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, BAR938HG shows the indoor and outdoor relative humidity and rates the comfort level. It also retains the maximum and minimum relative humidity readings. A remote thermo-hygro sensor is included with the unit. BAR938HG is able to receive and display readings from up to 3 remote sensors. The built-in barometer enables BAR938HG 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, BAR938HG is equipped with a moon phase scanner, which lets you check the moon phase of any day between 1990 and 2089. Other features include a HiGlo backlight, daily crescendo alarm with eight-minute snooze function, and extra-large display. No wire installation is required between the main and remote units. As BAR938HG operates at 433MHz, it can be used in the U.S. and most places in Continental Europe.

To enable this function, first activate the alarm function. Then enter the Pre-Alarm mode by pressing the ALARM button twice. The Pre-Al icon will be displayed. Press and hold the ALARM button for 3 seconds to set the operating time interval for this pre-alarm function. Use the UP or DOWN button to select from the 4 timeintervals: 15, 30, 45 or 60 minutes. Press the ALARM button to confirm and exit. The pre-alarm function will be enabled automati4
If no signals are received when the remote temperature and humidity is selected, blanks will be displayed. Press and hold the CHANNEL button to enforce a search. This is useful in synchronizing the transmission and reception of the remote and main units. If that fails, check if the remote unit is still in place. Make sure the transmission is within range and path is clear of obstacles and interference. Repeat this procedure whenever you find discrepancies between the reading shown on the main unit and the remote unit.

NOTE ON C AND F

The outdoor temperature display on the main unit is dominated by the selection on the C/F slide switch of the main unit. Whatever the display unit of the remote sensor is, it will only apply to the remote sensor itself and the temperature will be automatically converted to the chosen one of the main unit.
3. The Sunny icon, when applies to night time, implies clear weather.

COMFORT LEVEL INDICATORS

The comfort level indicators COM, WET or DRY will tell you if the curent environment is comfortable, too wet or too dry. The comfort indicators will appear on the display of the main unit when the following conditions are satisfied: Indicator displays on the unit Shows that the Current Environment Ideal range for both relative humidity and temperature Contains excess moisture Contains inadequate moisture
MAXIMUM AND MINIMUM TEMPERATURES
The maximum and minimum recorded temperatures will be automatically stored in memory. To display them, press MEMORY to toggle among the maximum, minimum and current temperatures. The respective MAX or MIN indicator will be displayed. To clear the memory, hold down MEMORY for three seconds. The maximum and minimum temperatures will be erased. If you press MEMORY now, the maximum and minimum temperatures and humidities will have the same values as the current one until different readings are recorded.

HOW TO CHECK THE BAROMETRIC PRESSURE
The current and historical barometric pressure is shown on the atmospheric pressure window. For users staying at a higher altitude such as in the mountain area, sea-level barometric pressure applies. In this case, press and hold HISTORY button to enter the altitude compensation setting mode. Use the UP or DOWN button to select from 100 to 2500 meters (whichever appropriate). Press HISTORY button to confirm and exit. If the altitude changes, the ALT icon will flash to indicate such change. It will stop flashing when the pressure reading is recorded again. The atmospheric pressure can be displayed in mb/hPa or inHg. The pressure unit is selected on the atmospheric pressure slide switch inside the battery compartment. If you want to check the pressure history for a particular hour during the past 24 hours, press the HISTORY button. Each press on the button will go back by an hour. The recorded atmospheric changes for the past 24 hours are displayed in a bar chart above the atmospheric pressure window.
