USER'S MANUAL

INTRODUCTION

Congratulations on your purchase of the RMR112 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 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.

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,

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 trans-

missionrange,which,inusualcircumstances, is 20to30 meters.

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 AND CHANNEL

INSTALLATION: REMOTE UNIT

1. Remove the screws on the battery compartment.

2. Select the channel number on the CHANNEL slide switch.

3. Select the temperature display unit on the C/F slide switch.

4. Install 2 alkaline batteries (UM-4 or “AAA” size 1.5V) strictly

according to the polarities shown.

5. Replace the battery compartment door and secure its screws.

HOW TO USE THE TABLE STAND

OR WALL MOUNTING

The main unit has a removable table stand, which when connected,

can support the unit on a flat surface. Or you can remove the stand

Note that once a channel is assigned to a remote unit, you can only

change it by removing the batteries or resetting the unit.

BATTERY INSTALLATION: MAIN UNIT

1. Slide open the battery compartment door.

2. 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

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.

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

thantwo minutes, blanks “---” will be displayeduntil further read-

ings 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 mea-

suring range of the main unit or the remote unit (stated in

wpecification), 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.

THE RESET BUTTON

This button is only used when the unit is operating in an unfavor-

able 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 trans-

mitting temperature readings at 30-second intervals.

Themain unit will also start searching for signals for about a minute

once batteries are installed. Upon successful reception, the indi-

vidual 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.

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.

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:

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.

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 batter-

ies of outdoor units will freeze, lowering their voltage sup-

ply and the effective range.

3. The transmission is within range and path is clear of obstacles

and 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 temporarily reception failure. This is nor-

mal and does not affect the general performance of the product.

The transmission and reception of temperature readings will re-

sume once the interference recedes.

NOTE ON °C AND °F

Theunit of temperature display is selectedon the °C/°Fslideswitch.

Select °C for Centigrade or °F for Fahrenheit.

Note that the remote temperature display on the main unit is domi-

nated 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

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 2. Hour-Minute-Day of the Week (of local time)

-------------------------------------------------------

Eachpresson 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.

ABOUT RADIO RECEPTION

The RMR112 is designed to automatically synchronize its calen-

dar 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.

For better reception, place the clock away from metal objects and

electrical appliances to minimize interference.

If you wish to disable the auto-reception feature, press the but-

ton for three seconds. The radio reception signal will disappear.

The unit will not respond to radio signals.

To enable the feature again, press the button for three seconds.

The radio reception signal will start blinking to initiate reception

automatically.

HOW TO SET THE CLOCK MANUALLY

To set the clock manually, hold MODE/SET for three seconds.

The display will return to MODE 1, with the hour digits blinking.

Use or to select the hour. Keep pressing the button will in-

crease or decrease the value rapidly.

Press MODE/SET to confirm. The minute digits will blink. Re-

peat 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.

If there is an item you do not wish to change, simply press MODE/

SET to bypass the item.

When you are done, press MODE/SET to exit. The display will

return to the mode last chosen.
