GB
easier synchronization between the transmission and reception
of signals.
4. Position the remote sensor and main unit within effective
transmission range, which, in usual circumstances, range of 100
feet (30 meters) under ideal conditions.
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 sensors are weather resistant, they should be
placed away from direct sunlight, rain or snow.
BATTERYINSTALLATION:MAINUNIT
1. Gently lift up the tab on the battery compartment door.
2. Insert four (4) UM-3 or “AA” size batteries.

GETTINGSTARTED
Once batteries are placed in a given remote sensor unit, it will start
transmitting information at 40-second intervals.
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 second line and the respective humidity
reading on the third 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 [CHANNEL] &[MEM] 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 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-wave icon.
Todisplaytemperature/humidityreadingsfromthemainunit:
• Press [CHANNEL] until a dot is displayed in the box under the
kinetic-wave.
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-wave.
DISCONNECTED SIGNALS
If without obvious reasons the display for a particular channel goes
blank,press[CHANNEL]&[MEM]toenforce animmediate 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, which will lower 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 temporary reception failure. This is normal and
does not affect the general performance of the product. The
transmission and reception of temperature and humidity readings
will resume once the interference recedes.

Each press on the [MODE/SET] 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 [] button is pressed.
ABOUTRADIORECEPTION
The BAR112HGA is designed to automatically synchronize its
calendar clock when it is within range of the radio signal from the
U.S. Atomic clock.
When the unit is receiving radio signal, the RADIO RECEPTION
signal will start to blink. A complete reception generally takes
about 2to 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 takes 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
[ ZONE ] button for three seconds. The radio reception signal []
and the outline of the US-Map icon will disappear. The unit will
not respond to radio signals.
To enable the feature again, press the[ ](clock) button for three
seconds.
The radio reception signal [ ] and the outline of the US-Map icon
will start blinking to initiate reception automatically.
