User manual OREGON SCIENTIFIC EMR812A

[. . . ] RESET Returns all user programmed settings to original factory set values F. REMOVABLE TABLE STAND For standing the remote unit on a flat surface 3. This will ensure synchronization between the remote unit and the main unit. Position the remote unit and main unit within effective transmission range, which, in usual circumstances, is 30 meters. [. . . ] Note : When the temperature falls befow freezing point, the batteries of outdoor units will freeze, lowering their voltage supply and the effective range. The transmission is within range and the path is clear of obstacles and interference. Shorten the distance when necessary. If no signals are received, blanks " " will be displayed and the kinetic wave icon will show " ". Press CHANNEL and MEM simultaneously to enforce another search for about 30 seconds. This is useful in synchronizing the transmission and reception of the remote and main units. Repeat this step whenever you find discrepancies between the reading shown on the main unit and that on the respective remote unit. TEMPERATURE TREND The temperature trend indicator on the screen shows the trend of readings collected at that particular remote site. Three trends, rising, steady and falling, will be shown. Arrow indicator Temperature Trend Rising Steady Falling HOW TO CHECK REMOTE AND INDOORS TEMPERATURES The indoors temperature is shown on the bottom line of the display. As for the remote sites or channels, press CHANNEL to go from one channel to another. The kinetic wave display on the channel number indicates the reception of that particular channel is in good order. DISCONNECTED SIGNALS If without obvious resasons the display for a particular channel 5 If the temperature goes above or below than the temperature measuring range of the main unit or the remote unit ( stated in specification), the display will show "HHH" or "LLL". GB GB HOW TO READ THE KINETIC WAVE DISPLAY The kinetic wave display shows the signal receiving status of the main unit. are HOW TO USE TEMPERATURE ALARMS The temperature alarms allow you to set the upper and lower limits of readings for individual channels. An "OFF" message will be displayed if the alarm for that limit is turned off. If this is the first time you set the limits, the lower limit will start from -50°C (-58°F) and the upper limit +70°C (158°F). The respective HI, LO or both indicators will light up to signify the status of the alarm. When an alarm activates, the display will switch to the respective channel with the display flashing. It will alarm again if the temperature continues to exceed the set limit. To disable an alarm altogether, select the channel and use TEMP AL ON/OFF to turn it off. If you have set the upper and lower temperatures for more than one 6 MAXIMUM AND MINIMUM TEMPERATURES The maximum and minimum recorded indoor temperatures and those of each channel will be automatically stored in memory. Press MEM once to display the maximum temperature and again the minimum temperature. The display will return to the last screen with maximum and minimum temperature erased from memory. If you press MEM now, the maximum and minimum temperatures will have the same values as the current ones until different readings are recorded. channel and the limits are exceeded, the alarm will activate with the display switching from one channel to another at five seconds intervals. As for the remote unit, it comes with a wall-mount holder and a removable stand. [. . . ] Always read the user's manual thoroughly before operating the unit.
