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.

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.

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

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.
