INTRODUCTION

Congratulations on your purchase of the RMR183/RMR183U Long-Range (60 meters) Multi-Channel In-Out Thermometer with 433MHz cable free sensor and radio-controlled calendar clock.

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 a large display for indoor 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. No wire installation is required as the RMR183/RMR183U 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) (or Radio signal MSF-60 from Rugby, England for UK version).

You can also set the calendar clock manually when it is off range. Other features include five-language display, crescendo daily alarm and interchangeable display modes.

BEFORE YOU BEGIN

For best operation,

1. Assign different channels to different remote units.
2. Insert batteries for remote units before doing so for the main unit.
3. Place the main unit as close as possible next to the remote unit and reset the main unit after installing batteries. This will ensure easier synchronization between the transmission and reception of signals.
4. Position the remote unit and main unit within effective transmission range, which is 60 meters in open area.

Note that the effective range is vastly affected by the building materials and where the main and remote units are positioned. Try various set-ups for best result.

Though the remote units are weather proof, they should be placed away from direct sunlight, rain or snow.

BATTERY INSTALLATION AND CHANNEL SETTING: REMOTE UNIT

The remote unit uses two (2) UM-4 or "AAA" size 1.5V batteries.

Installation:

1. Remove the screws on the battery compartment.
2. Select the channel on the CHANNEL slide switch.
3. Insert the batteries strictly according to the polarities shown
4. Replace the battery compartment door and screws
   

Note:

1. Replace batteries when the low-battery indicator of a particular channel activates on the main unit.
2. Once a channel is assigned to a remote unit, it can only be changed by removing the batteries or resetting the unit.

BATTERY INSTALLATION: MAIN UNIT

1. Open the battery compartment door.
2. Install 2 batteries (UM-3 or "AA" size 1.5V) strictly according to the polarities shown.
3. Replace the battery compartment door.
   

LOW BATTERY WARNING

When it is time to replace batteries, the low-battery indicator will show up when the corresponding channel is selected. The battery level of the main unit will be shown on the indoor temperature when it is running low.

HOW TO USE THE TABLE STAND OR WALL MOUNTING

The main unit has a removable table stand, which when installed, can support the unit on a flat surface. Or you can remove the stand and mount the unit on a wall using the recessed screw hole.

As for the remote unit, it comes with a wall-mount holder and a removable stand. Use either to hold the unit in place.

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.

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 indoor temperature on the second line. The main unit will automatically update its readings at about 30-second intervals.

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 corresponding remote unit.

HOW TO CHECK REMOTE AND INDOOR TEMPERATURES

The indoor 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 if 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 if 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 the temperature measuring range of the main unit or the remote unit (stated in specification), the display will show "HHH" or "LLL".

TEMPERATURE TREND

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	TEMP	TEMP	TEMP
Temperature Trend	Rising	Steady	Falling

MAXIMUM AND MINIMUM TEMPERATURES

The maximum and minimum recorded indoor temperatures and those of outdoor channels 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.

NOTE ON °C AND °F

The unit of temperature display is selected with the °C/°F slide switch. Select °C for Centigrade or °F for Fahrenheit.

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 asnecessary.
   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 obstaclesand interference. Shorten the distance when necessary.

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 temporary 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.

CALENDAR AND ALARM TIME DISPLAY

The calendar and alarm time share the same section of display. The calendar is displayed in day-month format. When the calendar is displayed, pressing [ALARM] once will change the display to the alarm time. Another press on the button will activate the alarm. A third press will deactivate it.

To display the calendar, press [MODE] once.

ABOUT RADIO RECEPTION

The RMR183/RMR183U is designed to automatically synchronize its calendar clock once it is brought within range of the Frankfurt DCF77 radio signal. (Rugby MSF-60 Radio signal for UK version).

When the RMR183/RMR183U is within range, the radio-controlled mechanism will override all manual settings.

When the unit is receiving radio signal, the radio-reception Signal will start to blink. Generally, complete reception take 2 to 10 minutes depending on the strength of the radio signal.

When the reception is complete, the radio-reception Signal will stop blinking.

For better reception, place the unit away from metal objects and electrical appliances to minimize interference.

If you wish to disable the auto-reception feature, press the [ ] and [ ] buttons simultaneously for two seconds. The radio-reception Signal [ ] will disappear. The unit will not respond to radio signals.

To enable the feature again, hold down the [ ] and [ ] buttons again. The radio-reception signal will start blinking to initiate reception automatically.

HOW TO SET THE CALENDAR CLOCK MANUALLY

When the calendar is displayed, press [MODE] for two seconds. The month digits will start to blink.

Enter the month using the [ ] and [ ] buttons. Hold down either button to rapidly increase or decrease the value.

Press [MODE] to confirm and proceed to set the day, display language, day-of-the-week, hour and minute.

For the display language, you can choose between English (E), German (D), French (F), Italy (I), Spanish (S).

The day-of-the-week display for the languages is as follows:

After setting the minutes, press[MODE] to return to normal display. If changes are made on the minutes, the seconds will reset and start from zero.

TIME DISPLAY MODE

When the display is in calendar mode, press [MODE] once to change between the hour, minute, seconds display to hour, minute, Day-of-Week display.

HOW TO SET AND ACTIVATE THE ALARM
