The basic package comes with a main unit, which is the temperature and calendar clock station, and a remote unit, the thermo sensor. The main unit has large read-outs for indoors temperature, calendar clock and temperatures collected and transmitted by the remote unit. The main unit can support up to three remote units. The main unit is capable of keeping track of the maximum and minimum temperature of different sites. And no wire installation is required and the RMR112 operates at 433MHz. As for the calendar clock, it is radio-controlled. It automatically synchronizes its current time and date when it is brought within an approximate 1500km radius of the radio signal generated from Frankfurt, Germany (DCF77). You can also set the calendar clock manually when it is off range. Other features include four-language display, four-step crescendo dual alarms and interchangeable display modes. 1 GB GB A FOUR-LINE DISPLAY Facilitates easy reading of remote and indoors temperatures and calendar clock B CHANNEL BUTTON Selects among different channels C MEMORY BUTTON Recalls the maximum or minimum temperature of individual channels D ALARM [24HR OFF] BUTTON Sets the time for the alarms E MODE/SET BUTTON Toggles the display modes and confirms entry while setting the values for display F RADIO RECEPTION SIGNAL Indicates the condition of radio reception G UP ( v ) BUTTON Advances the value of a setting H DOWN ( w ) BUTTON Decreases the value of a setting I ALARM [ AL ON/OFF] BUTTON Enables or disables the alarms J RESET BUTTON Returns all settings to default values K °C/°F SLIDE SWITCH Selects between degree Centigrade (°C) and Fahrenheit (°F) 2 L BATTERY COMPARTMENTS Accommodates two UM-3 or "AA" size 1.5V alkaline batteries M REMOVABLE TABLE STAND For standing the main unit on a flat surface N WALL-MOUNT RECESSED HOLE For mounting the main unit on a wall MAIN FEATURES: REMOTE UNIT A LCD Displays the current temperature monitored by the remote unit B LED INDICATOR Flashes when the remote unit transmits a reading C °C/°F SLIDE SWITCH Selects between Centigrade (°C) and Fahrenheit (°F) D CHANNEL SLIDE SWITCH Designates the remote unit Channel 1, Channel 2 or Channel 3 E F RESET BUTTON Returns all settings to default values BATTERY COMPARTMENT Accommodates two AAA-size batteries G BATTERY DOOR H WALL-MOUNT HOLDER Supports the remote until in wall-mounting I MOVABLE TABLE STAND For standing the remote unit on a flat surface reset the main unit after installing batteries.

Install 2 alkaline batteries (UM-3 or "AA" size 1.5V) strictly according to the polarities shown. 3. Replace the battery compartment door. LOW BATTERY WARNING Wall-mount When it is time to replace batteries, the respective low-battery indicator will show up when the respective channel is selected. The battery level of the main unit will be shown on the indoor temperature when it is running low. Table Stand 4 THE RESET BUTTON This button is only used when the unit is operating in an unfavorable way or malfunctioning. Use a blunt stylus to hold down the button. All settings will return to their default values. HOW TO CHECK REMOTE AND INDOOR TEMPERATURES The indoors temperature is shown on the second 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. If no readings are received from one particular channel 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 press CHANNEL and MEMORY simultaneously to enforce an immediate search. Of course no reading will be shown if no remote unit is assigned to that channel. If the temperature goes above or below than the temperature measuring range of the main unit or the remote unit (stated in wpecification), the display will show "HHH" or "LLL". GETTING STARTED Once batteries are in place for the remote units, they will start transmitting temperature readings at 30-second intervals. The main unit will also start searching for signals for about a minute once batteries are installed. Upon successful reception, the individual channel temperatures will be displayed on the top line and the indoors temperature on the bottom line. The main unit will automatically update its readings at about 30-second intervals. TEMPERATURE TREND If no signals are received, blanks "----" will be displayed and the kinetic wave icon will show " ". Press CHANNEL and MEMORY 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. The temperature trend indicator on the screen shows the trend of samplings collected at that particular remote site. Three trends, rising, steady and falling, will be shown. Arrow indicator Temperature Trend 5 Rising Steady Falling GB GB HOW TO READ THE KINETIC WAVE DISPLAY The kinetic wave display shows the signal receiving status of the main unit. There are three possible forms: The unit is in searching mode. Temperature readings are securely registered. No signals. DISCONNECTED SIGNALS If without obvious reasons the display for a particular channel goes blank, press CHANNEL and MEMORY to enforce an immediate search. If that fails, check: 1. The remote unit of that channel is still in place. 2. The batteries of both the remote unit and main unit. Replace as necessary. Note: When the temperature falls below freezing point, the batteries of outdoor units will freeze, lowering their voltage supply and the effective range. 3. The transmission is within range and path is clear of obstacles and interference. Shorten the distance when necessary. MAXIMUM AND MINIMUM TEMPERATURES The maximum and minimum recorded indoor temperatures and those of each channel will be automatically stored in memory. To display them, 1. Select the channel to be checked. 2. Press MEMORY once to display the maximum temperature and again the minimum temperature. The respective indicators, MAX or MIN will be displayed. To clear the memory, hold down MEMORY for two seconds. The maximum and minimum temperatures will be erased. If you press MEMORY now, the maximum and minimum temperatures will have the same values as the current ones until different readings are recorded. TRANSMISSION COLLISION Signals from other household devices, such as door bells, home security systems and entry controls, may interfere with those of this product and cause temporarily reception failure. This is normal and does not affect the general performance of the product. The transmission and reception of temperature readings will resume once the interference recedes. NOTE ON °C AND °F The unit of temperature display is selected on the °C/°F slide switch. Select °C for Centigrade or °F for Fahrenheit. Note that the remote temperature display on the main unit is dominated by the selection on the °C/°F slide switch of the main unit. Whatever the display units of the remote sensors are, they will be 6 automatically converted to the chosen one of the main unit. CALENDAR CLOCK DISPLAY MODES The RMR112 supports four display modes in the sequence of: MODE 1. Hour-Minute-Second (of local time) -------------------------------------------Day-Month (of local time) MODE 4. Hour-Minute-Day of the Week (of second time zone) ---------------------------------------------------------------Day-Month (of second time zone) Each press on the MODE button will toggle the display in the above order. Note: The bottom line of the display will be replaced by the alarm time if the [24HR OFF] button is pressed. MODE 2. Hour-Minute-Day of the Week (of local time) ------------------------------------------------------Day-Month (of local time) ABOUT RADIO RECEPTION The RMR112 is designed to automatically synchronize its calendar clock once it is brought within range of the Frankfurt DCF77 radio signal. When the RMR112 is within range, its radio-control mechanism will override all manual settings. When the unit is receiving radio signal, the radio reception signal 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 signal will stop blinking. The strength of the reception for the last full hour will be indicated. MODE 3. Hour-Minute-Day of the Week (of local time) ------------------------------------------------------Hour-Minute (of second time zone) 7 GB GB - Strong Press MODE/SET to confirm. The minute digits will blink. Repeat the same procedure to set the minutes, then the day-of-month, month, display language, day-of-week and offset for the second time zone. Note that the time and date are displayed in 24-HOUR clock and DAY-MONTH format, respectively. For display language, you can choose among English (E), German (D), French (F) and Italian (I)-in that order. Day-of-week is the usual sequence of Monday through Sunday. For the second time zone, which is indicated by the ZONE ICON, enter the hour offset using the or buttons and the RMR212 will calculate the second time accordingly.
