[. . . ] Position the remote unit and main unit within effective transmission range, which, in usual circumstances, is 20 to 30 meters. Note that the effective range is vastly affected by the building materials and where the main and remote units are positioned. Though the remote units are weather proof, they should be placed away from direct sunlight, rain or snow. 2d) LOW BATTERY WARNING If it's time to replace batteries for the remote sensors or the unit, the respective low-battery indicator [ ] will show up on the outdoor temperature display (for the thermo/hygro sensor) or on the clock display (for the unit). [. . . ] 4a) HOW TO CHECK REMOTE AND INDOOR TEMPERATURES The wave display on the outdoors temperature indicates the reception of the remote unit is in good order. If no readings are received from the remote unit for more than two minutes, blanks " " will be displayed until further readings are successfully searched. Check the remote unit is sound and secure. You can wait for a little while or Hold [ ] for 2 seconds to enforce an immediate search. If the temperature or humidity goes above or below than the measuring range of the main unit or the remote unit (stated in specification), the display will show " " & "HHH" or "LLL" respectively. The unit can be set to automatically scan and display readings from the remote sensors, the display will show the readings from one channel for about 4-seconds and then proceed to the next channel display. There are three possible forms: The unit is in searching mode. To display them, Press [ MEM ] once to display the maximum readings and again the minimum readings. the respective indicators , [ MAX ] or [ MIN ] will be displayed. To clear the memory, hold down [ MEM ] for two seconds. the maximum and minimum readings will be erased. If you press [ MEM ] now, the maximum and minimum readings will have the same values as the current ones until different readings are recorded. 4d) TEMPERATURE ALARM Weather Station is equipped with a temperature alarm whereby a user-defined temperature can be selected. With one further pressing of the TEMP ALARM button the data entered is confirmed. Three trends: rising, steady, and falling will be shown. 4f) COMFORT LEVEL INDICATORS The comfort level indicators COM, WET or DRY will tell you if the current 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 COM Temperature Range 20°C to 25°C (68°F to 77°F) -5°C -+ 50°C (23°F - 122°F) -5°C -+ 50°C (23°F - 122°F) Less than 20°C (68°F) or More than 25°C (77°F) 72 Humidity Range 40%RH70%RH OVER 70%RH Below 40%RH 40%RH to 70%RH Shows that the Current Environment Ideal range for both relative humidity and temperature Contains excess moisture Contains inadequate moisture No comment After the batteries are installed. the clock will automatically search the radio signal. It takes about 3-5 minutes to finish this process. To enable the auto-reception feature again, holds the "Up" for 2 seconds again to force it receive and allow it receive at desired time.
