BEFORE YOU BEGIN

ToensureproperfunctioningoftheEMGR819LR(MRC800)follow

this setup procedure.

For best operation:

1. Assign different channels to different remote units.

2. Insert batteries for remote units before doing so for the main

unit (see instructions for battery installation).

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

transmission range, which, in usual circumstances, is up to 100

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.

GETTING STARTED

Once batteries are placed in a given remote sensor unit, it will start

transmitting information at 40-second intervals.

Also, for approximately a 3-minute duration, the main unit will

automatically search for signals once batteries are installed. Upon

successful reception, the individual channel temperature reading

will be displayed on the top line and the respective humidity

reading on the bottom line. The main unit will automatically

update its readings at about 40-second intervals.

If no signals are received, blanks “ --- ” will be displayed and the

kinetic wave icon will not show.

To force a signal search:

• Press and hold IN/REMOTE for 2-seconds to enforce a

3-minute search.

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

Display of readings from a remote sensor or the main unit is a one-

step procedure. The remote sensor channel or the main unit display

The temperature range is from -50°C (-58°F) to +70°C

(158°F).

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.

The humidity range is from 2% to 98%.

If this is the first time you set the limits, the lower limit will

startfrom 2%andtheupper limit98%Otherwise,the reading

will start from the humidity last selected.

3. Repeat the steps to set the upper humidity setting and the lower

temperature and humidity settings.

4. When finished, press HI/LO to set another limit or wait

16-seconds and the unit will automatically return to the normal

display. The respective HI, LO or both indicators will light up

to signify the status of the alarm.

If in another channel other than channel one is selected, when the

alarm activates the display will switch to channel-1 and the display

will flash. If left untouched, the alarm will activate for 1-minute.

Pressanykeytomomentarilystopthealarm.Thealarmwillactivate

again if the limit continues to be exceeded.

Note: If a second limit is passed while an alarm is active, the

first alarm will complete its 1-minute cycle and the alarm

will continue to activate for a second minute to indicate that

a second limit has been surpassed.

To disable an alarm:

DISCONNECTED SIGNALS

If without obvious reasons the display for a particular channel

goes blank, press IN/REMOTE 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 that 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 temporarily 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.

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 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.
