Multi-Channel In-Out Thermometer

with Cable Free Sensor and RF Clock

MODEL: RMR182

USER'S MANUAL

INTRODUCTION

Congratulations on your purchase of the RMR182 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 tempera-

ture 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 RMR182 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

RMR182_EN 8/16/04, 2:58 PM3

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

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. Gently lift the tab on 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.

4. Position the remote unit and main unit within effective trans-

mission 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. 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.

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

minuteoncebatteriesareinstalled.Uponsuccessfulreception,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.

When it is time to replace batteries, the low-battery indicator will

show up when the corresponding channel is selected. The battery

levelofthemainunitwillbeshownontheindoortemperaturewhen

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.

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.

HOWTO CHECK REMOTEAND

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 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.

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 clearthememory,holddown[MEMORY]fortwoseconds.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

arerecorded.

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.

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 automatically converted to the chosen one of the main 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:

DISCONNECTED SIGNALS

Ifwithoutobvious reasons the displayfor a particular channelgoes

blank, press [CHANNEL] and [MEMORY] to enforce an imme-

diate 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.

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.

The unit is in searching mode.

Temperature readings are

securely registered.

No signals.

ABOUT RADIO RECEPTION

TheRMR182isdesignedtoautomaticallysynchronizeitscalendar

clock once it is brought within range of the Frankfurt DCF77 radio

signal.

When the RMR182 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.Acomplete 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 in the last hour will be

indicated.

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

electrical appliances to minimize interference.

Ifyouwish todisabletheauto-receptionfeature,press the button

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 SETTHE CLOCK MANUALLY

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

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