cable free sensor and radio-controlled calendar clock (BAR122HG).
This unit has a large four-line liquid crystal display (LCD) for
displaying eather forecast information, in/outdoor temperatures
and relative humidity, radio frequency (RF) controlled calendar
clock, clock display of 2nd time-zone and dual daily alarms. Also,
the main unit can support up to three remote sensors.
Other features include eekday display in four abbreviated
languages, four-step crescendo alarm and interchangeable clock
display modes.

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. Place the main unit as close as possible next to the remote unit,
reset the main unit after installing batteries. This ill ensure

4
GB
easier synchronization bet een the transmission and reception
of signals.
4. Position the remote unit and main unit ithin effective
transmission range, hich, in usual circumstances, is up to 100
meters.
Note that the effective range is vastly affected by the building
materials and here the main and remote units are positioned. Try
various set-ups for best result.
Though the remote units are eather proof, they should be placed
a ay from direct sunlight, rain or sno .
BATTERY INSTALLATION: MAIN UNIT
1. Gently lift up the tab on the battery compartment door.
2. Insert four UM-3 or “AA” size alkaline batteries.
3. Replace the battery compartment door.
BATTERY AND CHANNEL INSTALLATION:
REMOTE UNIT
The remote thermo-hygro sensor unit uses t o (2) UM-4 or “AAA”
size alkaline batteries.
Follo these steps to install / replace batteries:
1. Remove the scre s on the battery compartment.
2. Select the channel number on the [CHANNEL] slide s itch.
3. Select the temperature display unit on the °C/°F slide s itch.
4. Insert the batteries strictly according to the polarities sho n
therein.
5. Replace the battery compartment door and secure its scre s.
Replace the batteries hen the lo -battery indicator of the particular
channel lights up on the main unit. (Repeat the steps described in
section “BEFORE YOU BEGIN”)
Note that once a channel is assigned to a remote unit, you can only
change it by removing the batteries or resetting the unit.

HOW TO USE THE TABLE STAND OR WALL
MOUNTING
The main unit has a removable table stand, hich hen connected,
can support the unit on a flat surface. Or you can remove the stand
and mount the unit on a all using the recessed scre hole.
As for the remote unit, it comes ith a all-mount holder and a
removable stand. Use either to hold the unit in place.

THE RESET BUTTON
This button is only used hen the unit is operating in an
unfavorable ay or malfunctioning. Use a blunt stylus to hold do n
the button. All settings ill return to their default values.
GETTING STARTED
Once batteries are placed in a given remote sensor unit, it ill start
transmitting information at 40-second intervals.
Also, for approximately a 3-minute duration, the main unit ill
automatically search for signals once batteries are installed. Upon
successful reception, the individual channel temperature reading
ill be displayed on the top line and the respective humidity
reading on the bottom line. The main unit ill automatically update
its readings at about 40-second intervals.

To force a signal search:
• Press and hold [CHANNEL] & [MEMORY] 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 henever you find discrepancies bet een the
reading sho n on the main unit and that on the respective remote
unit.
HOW TO CHECK REMOTE AND INDOOR
TEMPERATURE & HUMIDITY
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
is indicated in a box under the kinetic- ave icon.
To display temperature / humidity readings from the main unit:
• Press [CHANNEL] until a dot is displayed in the box under the
kinetic- ave.
To display temperature / humidity readings from a remote
sensor:
• Press [CHANNEL] until the appropriate remote sensor channel
is displayed in the box under the kinetic- ave.
DISCONNECTED SIGNALS
If ithout obvious reasons the display for a particular channel goes
blank, press [CHANNEL] & [MEMORY] 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 hen the temperature falls belo freezing point, the
batteries of outdoor units ill freeze, lo ering their voltage supply
and the effective range.
3. The transmission is ithin range and path is clear of obstacles
and interference. Shorten the distance hen necessary.
TRANSMISSION COLLISION
Signals from other household devices, such as door bells, home
security systems and entry controls, may interfere ith 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 ill resume once
the interference recedes.

REMOTE SENSOR SCANNING
The unit can be set to automatically scan and display readings from
the remote sensors and indoor readings. When the remote-sensor
mode is active, the display ill sho the readings from one channel
for about 4-second and then proceed to the next channel display.
To activate the remote-sensor scanning mode:
• Press and hold [CHANNEL] for 2-seconds.

Note: 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 lo er limit ill start
from -50°C (-58°F) and the upper limit +70°C (158°F). Other
ise, the reading ill 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 lo er limit ill start
from 2% and the upper limit 98% Other ise, the reading ill start
from the humidity last selected.
3. Repeat the steps to set the upper humidity setting and the lo er
temperature and humidity settings.
4. When finished, press [HI/LO] to set another limit or ait 16-seconds.

NOTE:
1. The accuracy of a general pressure-based eather forecast is
about 70% to 75%.
2. The eather 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 eather.
CALENDAR CLOCK DISPLAY MODES
The BAR122HG supports four time display modes in the sequence
of:
MODE 1. Hour-Minute-Second (of local time)
Day-Month (of local time)
MODE . 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/SET] button ill toggle the display in
the above order.
Note: The bottom line of the display ill be replaced by the alarm
time if the [ ] button is pressed.
ABOUT RADIO RECEPTION
The BAR122HG is designed to automatically synchronize its
calendar clock once it is brought ithin range of the Frankfurt
DCF77 radio signal.
When the BAR122HG is ithin range, its radio-control mechanism
ill override all manual settings.
When the unit is receiving radio signal, the RADIO RECEPTION
signal ill start to blink. A complete reception generally takes
about t o to 10 minutes, depending on the strength of the radio
signal.
When the reception is complete, the RADIO RECEPTION signal
ill stop blinking. The strength of the reception ill remain until
the next scanning cycle backs place.
For better reception, place the clock a ay from metal objects and
electrical appliances to minimize interference.
