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.

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.
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.
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 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

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
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 inter-
vals.
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.

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
immediatesearch. Ofcourse noreadingwill beshownif noremote
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.

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
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.
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
The RMR182 is designed to automatically synchronize its calen-
dar 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.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 in the last hour will be
indicated.
For better reception, place the clock away from metal objects and
electrical appliances to minimize interference.
