BATTERY INSTALLATION:
REMOTE UNIT
The remote unit uses two UM-4 or “AAA” size alkaline batteries.
Installation:
1. Remove the screws on the battery compartment.
2. Select the desired temperature scale by switching the °C/°F
switch located inside the battery compartment.
3. Select the channel number on the CHANNEL slide switch. Note
that once a channel is assigned to a remote unit, you can only
change it by removing the batteries or resetting the unit.
4. Insert the batteries strictly according to the polarities shown
inside the battery compartment.
5. Replace the battery compartment door and secure the screws.
Note: Disposed of improperly, batteries can be harmful.
Protect the environment by taking exhausted batteries to
authorized disposal stations.
BATTERY INSTALLATION: MAIN UNIT
1. Gently lift the tab on the battery compartment door.
2. Insert four UM-3 or “AA” size alkaline batteries.
3. Replace the battery compartment door.
Note: For both the remote sensor and the main unit, replace batteries when
they are low. The low battery indicator [ ] in the indoor or / and outdoor
temperature window will be displayed when the batteries are low.
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:
The unit is in searching mode.
Channel registered in search mode.
No signal received in search mode.

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: Theremotetemperaturedisplayonthemainunitisdominated

the display units of the remote sensors, they will be automatically
converted to the choice of the main unit.
WEATHER FORECAST FUNCTION
The unit is capable of detecting atmospheric pressure changes.

12 to 24 hours. The effective range covers an area of 30 to 50 km.
MAXIMUM AND MINIMUM
TEMPERATURES
The maximum and minimum recorded temperatures will be
automatically stored in memory. To display them, press MEM.
Press MEM again to alternate between the maximum, minimum,
and current temperatures. The respective MAX or MIN indicator
will be displayed.
Toclearthememory,press MEMbuttonandholdforthreeseconds.
Themaximum andminimum-recorded temperatures will be erased.
Subsequently,if you pressMEMafter thememory has beenerased,
the maximum and minimum temperature will have the same values
as the current reading.
DISCONNECTED SIGNALS
If without obvious reasons the display for a particular channel
goesblank,press CHANNELandMEMsimultaneously toenforce
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 if
necessary.
Note: When the temperature falls below freezing point, the
batteries of outdoor units will freeze lowering their voltage
supply and the effective range.

NOTE:
1. The accuracy of a general pressure-based weather forecast is
about 70% to 75%.
2. The weather forecasts from this unit are predictions that cover
the next 12 to 24 hours. It may not necessarily reflect the current
situation.
3. The “Sunny” icon, as applies to nighttime, implies clear weather.
CALENDAR CLOCK DISPLAY MODES
The BAR112 supports four time display modes in the sequence of:
MODE 1. Hour-Minute-Second (of local time)
Day-Month (of local time)
MODE 2. Hour-Minute-Day of the Week (of local time)
Day-Month (of local time)
MODE 3. Hour-Minute-Day of the Week (of local time)
Hour-Minute (of alternate time zone)
MODE 4. Hour-Minute-Day of the Week (of second time zone)
Day-Month (of alternate time zone)
Each press on the MODE button will toggle the display in the
above order.
Note: The bottom line of the display will be replaced by the alarm
time if the ALARM SET [ ] button is pressed.
ABOUT RADIO RECEPTION
The BAR112 is designed to automatically synchronize its calendar
clock once it is brought within range of the Frankfurt DCF77 radio
signal.
When the BAR112 is within range, its radio-control mechanism
will override all manual settings.
When the unit is receiving radio signal, the RADIO RECEPTION
signal will start to blink. A complete reception generally takes
about two to 10 minutes, depending on the strength of the radio
signal.
When the reception is complete, the RADIO RECEPTION signal
will stop blinking. The strength of the reception will remain until
the next scanning cycle backs place.
For better reception, place the clock away from metal objects and
electrical appliances to minimize interference.

If you wish to disable the auto-reception feature, press the
buttonforthreeseconds.Theradioreceptionsignal[ ]willdisappear.
The unit will not respond to radio signals.
To enable the feature again, press the button for three seconds.
The radio reception signal [ ] will start blinking to initiate
reception automatically.
HOW TO SET THE CLOCK MANUALLY
Toset the clockmanually, hold MODE/SETfor three seconds.The
hour digits will blink.
Press or select the hour. Keep pressing the button to
increase or decrease the value rapidly.
Press MODE/SET to confirm. The minute digits will blink.
Repeat the same procedure to set the minutes, hour, current date,
month, display language, day-of-week and offset for the alternate
time zone.
Note: The time and date are displayed in 24-HOUR clock format.
For the language display, you can choose among English (E),
German (D), French (F) and Italian (I). Day-of-week is in the usual
sequence of Monday through Sunday.
For the alternate time zone, which is indicated by the ZONE icon,
enterthehour offset using the and buttonsandtheBAR112
will calculate the second time accordingly.
If there is an item you do not wish to change, simply press MODE/
SET to bypass the item.
When you are done, press MODE/SET to exit. The display will
return to the mode last chosen.

The four-step crescendo function allows the alarm to start off
gently and step up its intensity every 20 seconds for four times.
Without interruption, the alarm will go off for a total of two
minutes.
If a second alarm goes off when the first alarm is sounding off, the
first alarm will be disabled automatically.

NOTE ON OUTDOOR-REMOTE
TEMPERATURE
Once batteries are in place in the remote unit, it will start
transmitting samplings at 30-second intervals.
If no signals are received when the outdoor-remote temperature is
selected, “ ” will be displayed. To force the main unit to
search for remote sensor signals, press MEM and CHANNEL
buttons simultaneously.
If that fails, check that the remote sensor is still in place. Make sure
the transmission is within range and the path is clear of obstacles
and interference.
NOTE ON SETTING REMOTE SENSOR
CHANNELS
The unit has an auto-scan function that sequentially displays
temperature readings of up to three remote sensors. In order to
function properly, each remote sensor must be set to different
channels.
THE RESET BUTTON
The 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.
