The EMR812 is an easy-to-use, state-of-the-art thermometer. The  
basic package comes with a main unit, which is the temperature  
station, and a remote unit, the thermo sensor.

The main unit has extra-large read-outs for indoors temperature  
and for that collected and transmitted by the remote unit. The main  
unit can support up to three remote units.  
The main unit is capable of monitoring temperature changes of  
remote sites. By setting the upper and lower temperature limits the  
alarm will activate when those limits are exceeded. Also, the maxi-  
mum and minimum temperature of different sites can also be  
retrieved quickly.

No wire installation is required between the main and remote units.  
As the EMR812 operates at 433MHz, it can be used in the U.S. and  
most places in Continental Europe.

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. Replace the battery compartment door.  
4. Insert the batteries strictly according to the polarities shown therein.  
5. Replace the battery compartment door and secure its screws.  
LOW BATTERY WARNING  
Replace the batteries when the low-battery indicator of the indoor  
temperature display lights up. (Repeat the steps described in  
section"BEFOREYOUBEGIN")

channel lights up on the main unit. (Repeat the steps described in  
sectionBEFOREYOUBEGIN”)  
Respectively, for a remote sensor unit, the low-battery icon will  
show when the channel is selected.  
Note that once a channel is assigned to a remote unit, you can only  
change it by removing the batteries or resetting the unit.  
GETTING STARTED  
BATTERY INSTALLATION: MAIN UNIT  
Once batteries are in place for the remote units, they will start  
transmitting temperature readings at 30-second intervals.  
The main unit uses two UM3 or "AA" size alkaline batteries.  
To install them,  
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 indoors temperature on the bottom line. The main unit will  
automatically update its readings at about 30-second intervals.  
1. Slide open the battery compartment door.  
2. Insert the batteries strictly according to the polarities shown therein.

immediate search. If this fails, check the following.  
1. The remote unit of that channel is still in place.  
2. The batteries of both the remote unit and main unit and replace  
as necessary.  
Note : When the temperature falls befow freezing point, the  
batteries of outdoor units will freeze, lowering their voltage  
supply and the effective range.  
If no signals are received, blanks “

simultaneously to enforce another search for about 30 seconds.  
This is useful in synchronizing the transmission and reception of  
the remote and main units.  
3. The transmission is within range and the path is clear of obstacles  
and interference. Shorten the distance when necessary.  
Repeat this step whenever you find discrepancies between the  
reading shown on the main unit and that on the respective remote  
unit.  
TEMPERATURE TREND  
The temperature trend indicator on the screen shows the trend of  
readings collected at that particular remote site. Three trends,  
rising, steady and falling, will be shown.

HOW TO READ THE KINETIC  
WAVE DISPLAY  
HOW TO USE TEMPERATURE ALARMS  
The temperature alarms allow you to set the upper and lower limits  
of readings for individual channels. The alarm will activate if a  
limit is exceeded. To set the alarm,  
The kinetic wave display shows the signal receiving status of the  
main unit. There are three possible forms:  
1. Select the channel to be set.  
2. PresstheHI/LObuttonfortheupper(HI)orlower(LO)limit. An  
“OFF” message will be displayed if the alarm for that limit is  
turned off.  
The unit is in searching mode.  
Temperature readings are  
securely registered.  
3. Use the ADVANCE ( s ) button to set the upper or lower  
temperature.  
No signals.  
If this is the first time you set the limits, the lower limit will start from  
-50°C (-58°F) and the upper limit +70°C (158°F). Otherwise, the  
reading will start from the temperature last selected.  
MAXIMUM AND MINIMUM  
TEMPERATURES  
Each press on the button will increase the temperature by one degree.  
Holding on the button will step up the increment by five.  
The maximum and minimum recorded indoor temperatures and  
those of each channel will be automatically stored in memory. To  
display them,  
4. Press TEMP AL ON/OFF button to switch on or off the Max./  
Min. temperature alarm. The set limit will be displayed.  
5. Press HI/LO button to set another limit or return to normal  
display. The respective HI, LO or both indicators will light up to  
signify the status of the alarm.  
1. Select the channel to be checked.  
2. Press MEM once to display the maximum temperature and again  
the minimum temperature. The respective indicators, MAX or  
MIN will be displayed.  
When an alarm activates, the display will switch to the respective  
channel with the display flashing. If undisturbed, it will alarm for  
one minute. Press any key to momentarily mute the alarm. It will  
alarm again if the temperature continues to exceed the set limit.

channel and the limits are exceeded, the alarm will activate with the  
display switching from one channel to another at five seconds  
intervals.  
As for the remote unit, it comes with a wall-mount holder and a  
removable stand. Use either to hold the unit in place.

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 resume  
once the interference recedes.  
Remote unit  
NOTE ON °C AND °F  
Wall-mount  
Table Stand  
The unit of temperature display is selected on the °C/°F slide  
switch. Select °C for Centigrade or °F for Fahrenheit.  
Note : 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.  
HOW TO USE THE TABLE STAND OR  
WALL MOUNTING  
THE RESET BUTTON  
The main unit has a retractable table stand, which when flipped  
open, can support the unit on a flat surface. Or you can flip close the  
stand and mount the unit on a wall using the recessed screw hole.  
This button is only used when the unit is operating in an  
unfavorable way or malfunctioning. Use a blunt stylus to hold  
down the button. All settings will return to their default values.
