BEFORE YOU BEGIN

For best operation,

1. Insert batteries for remote units before doing so for the main unit.

2. Position the remote unit and main unit within effective transmission range, which, in usual cir­cumstances, is 20 to 30 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.

BATTERY INSTALLATION: REMOTE UNIT

1. Remove the screws on the battery compartment.

2. Select the channel

3. Install 2 batteries (UM-3 or “AA” size 1.5V) strictly according to the polarities shown.

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

BATTERY INSTALLATION: MAIN UNIT

1. Open the battery compartment door.

2. Install 2 batteries (UM-3 or “AA” size 1.5V) strictly according to the polarities shown.

3. Replace the battery compartment door.

LOW BATTERY WARNING

When it is time to replace batteries, the respective low-battery indicator [ ] will show up on
the indoor or outdoor temperature.

HOW TO USE THE TABLE STAND OR WALL MOUNTING

The main unit has a removable table stand, which when connected, 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.

GETTING STARTED

Once batteries are in place for the remote unit, they will start transmitting temperature readings
at around 45 seconds intervals. The main unit will also start searching for signals for about two
minutes once batteries are installed. Upon successful reception, the outdoors temperatures will
be displayed. The main unit will automatically update its readings at about 45-second intervals.

If no signals are received, blanks “ ” will be displayed. Hold [

$

] for 2 seconds to enforce
another search for about 2 minutes. 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 remote unit.

HOW TO CHECK REMOTE AND INDOOR TEMPERATURES

The wave display on the outdoors temperature indicates the reception of the remote unit is in
good order. If no readings are received from the remote unit for more than two minutes, blanks

“ ” will be displayed until further readings are successfully searched. Check the remote
unit is sound and secure. You can wait for a little while or Hold [

$

] for 2 seconds to enforce an

immediate search. If the temperature goes above or below than the temperature measuring

range of the main unit or the remote unit (stated in specification), the display will show “ ”.

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 temperature, outdoor temperatures will be auto­matically stored in memory. To display them, Press [ MEM ] once to display the maximum read­ings and again the minimum readings. The respective indicators, [ MAX ] or [ MIN ] will be dis­played. To clear the memory, hold down [ MEM ] for two seconds. The maximum and minimum
readings will be erased.
If you press [ MEM ] now, the maximum and minimum readings will have the same values as the
current ones until different readings are recorded.

TEMPERATURE TREND

The trend indicator shows the trend of temperatures collected at that particular remote sight.
Three trends: rising, steady, and falling will be shown.

WEATHER FORECAST

The unit is capable of detecting atmospheric pressure changes. Based on collected data, it can
predict the weather for the forthcoming12 to 24 hours.

NOTE:

1. The accuracy of a general pressure-based weather forecast is about 70%.

2. The weather forecasts. It may not necessarily reflect the current situation.

3. The “Sunny” icon, as applies to night time, implies clear weather.

ATMOSPHERIC PRESSURE

The atmospheric pressure indicator, in the weather forecast window, uses arrows to indicate if
the atmospheric pressure is increasing, remaining stable, or decreasing.

DISCONNECTED SIGNALS

If without obvious reasons the display of the outdoor temperature goes blank, Hold [

$

] for 2
seconds to enforce an immediate search.
If that fails, check:

1. The remote unit 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 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.

CALENDAR CLOCK DISPLAY MODES

The clock and the calendar share the same section of the display. The calendar is displayed in
a day-month format.
Each press on the MODE button will change the display between clock with second, clock with
day of week, zone time with day of week. zone time with second and day-month.

HOW TO SET THE CLOCK

To set the clock manually, hold MODE for two seconds it will show the year. Use [

$

] or [#] to
change it. Press MODE to confirm. Repeat the same procedure to set the month, date, date­month format, 12/24, hour, minute, display language, zone time offset and °C/°F.

During the setting, press and hold [

$

] or [#] will increase or decrease the value rapidly.
For display language, you can choose among English (EN), German (DE), French (FR), Italian
(IT) and Spanish (SP) - in that order. If there is an item you do not wish to change, simply press
[ MODE ] to bypass the item. When you finished the change, press [ MODE ] to exit. The display
will return to the clock mode.

HOW TO SET AND ARM THE ALARM

To set an alarm,

1. Press [ALARM] once to display alarm time. If the alarm is disarmed, the time will be dis­played as “ OFF ”.

2. Hold [ALARM] for two seconds. The hour digits will blink.

3. Enter the hour using [

$

FAULTS AND TROUBLESHOOTING

The antenna symbol has disappeared

There is interference to the radio reception of the time signal.

The time is not received

As with all radio receivers, the base station can also experience certain reception restrictions
and transmitter interference. Fault sources include thunderstorm, metallic structural elements
in buildings, TVs, PCs, mobile phones or cordless phones. Transmitters can also be deactivated
for a time.
If the base station does not receive the time, move it to a different location. To switch the sta-

tion to reception, press the [

#

] button for at least one second. By pressing [#] button user

can search or stop searching the radio signal immediately.

Service life – no less than 3 years.
