USER'S MANUAL
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.
Thebasicpackagecomeswithamainunit,whichisthetemperature
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.

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 trans-
mission range, which is 60 meters in open area.

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.
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 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.

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.
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.
Toclearthememory,holddown[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

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.
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
DCF77radio signal. (Rugby MSF-60 Radio signal forUKversion).
When the RMR183/RMR183U is within range, the radio-con-
trolled 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.
The unit is in searching mode.
