USER’S MANUAL

INTRODUCTION

Congratulations on your purchase of the EMR812 Multi-Channel

In-Out Thermometer with 433MHz cable free sensor.

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. Initially place both units close together. This will ensure

synchronization between the remote unit and the main unit.

Then, install batteries for the main unit or reset the main unit.

4. Position the remote unit and main unit within effective

transmission range, which, in usual circumstances, is 30 meters.

Note : Building materials and where the main and remote units are

positioned can vastly affect effective range. 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 remote thermo-hygro sensor unit uses two (2) UM-3 or “AA”

size batteries.

Follow these steps to install / replace batteries:

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. Insert the batteries strictly according to the polarities shown therein.

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

Replacethebatterieswhenthelow-batteryindicatoroftheparticular

channel lights up on the main unit. (Repeat the steps described in

section“BEFOREYOUBEGIN”)

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

The main unit uses two UM3 or "AA" size alkaline batteries.

To install them,

1. Slide open the battery compartment door.

2. Insert the batteries strictly according to the polarities shown therein.

3. Replace the battery compartment door.

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")

Respectively, for a remote sensor unit, the low-battery icon will

show when the channel is selected.

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 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

thekineticwaveiconwillshow“ ”. PressCHANNELandMEM

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 CHECK REMOTE AND

INDOORS TEMPERATURES

The indoors temperature is shown on the bottom line of the

display.

Asfortheremotesitesorchannels,pressCHANNELtogofromone

channelto another.Thekineticwavedisplay onthe channelnumber

indicates the reception of that particular channel is in good order.

DISCONNECTED SIGNALS

If without obvious resasons the display for a particular channel

goes blank “ ”, press CHANNEL and MEM to enforce an

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.

3. Thetransmissionis withinrangeandthe pathisclearof obstacles

and interference. Shorten the distance when necessary.

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.

If the temperature goes above or below than the temperature meas-

uring range of the main unit or the remote unit ( stated in specifi-

cation), the display will show “HHH” or “LLL”.

channel and the limits are exceeded, the alarm will activate with the

display switching from one channel to another at five seconds

intervals.

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.

NOTE ON °C AND °F

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
