NOTE ON °C AND °F

The temperature display designation of °C or °F on the main display
unit will override the display selection made on the remote sensor.
Whatever the display unit of the remote sensor is, it will only apply
to the remote sensor itself and the temperature unit will automatically
be converted to the one of the main unit. (i.e. °F)

MAINTENANCE

When handled properly, this unit is engineered to give you years
of satisfactory service. Here are a few product care instructions:

1. Do not immerse the unit in water. If the unit comes in contact
with water, dry it immediately with a soft lint-free cloth.

2. Do not clean the unit with abrasive or corrosive materials.
Abrasive cleaning agents may scratch the plastic parts and
corrode the electronic circuit.

3. Do not subject the unit to excessive: force, shock, dust,
temperature, or humidity. Such treatment may result in
malfunction, a shorter electronic life span, damaged batteries, or
distorted parts.

4. Do not tamper with the unit’s internal components. Doing so
will terminate the unit’s warranty and may cause damage. The
unit contains no user-serviceable parts.

5. Only use new batteries as specified in this instruction manual.
Do not mix new and old batteries as the old batteries may leak.

6. Read this instruction manual thoroughly before operating the
unit.

ABOUT RADIO RECEPTION

The BAR122HGA 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 BAR122HGA is new and initially set
up, reception of the U.S. Atomic clock signal can take up to 72
hours.

When the unit is receiving radio signal, the RADIO RECEPTION
signal will start to blink. A complete reception generally takes
about 2 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 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

[ TIME /

] and the outline of the US-Map icon will disappear. The unit will

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] & [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 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

TEMPERA TURE & HUMIDITY

Display of readings from a remote sensor or the main unit is a one­step procedure. The remote sensor channel or the main unit display
is indicated in a box under the kinetic-wave icon.

Channel 3

To display temperature / humidity readings from a remote

• 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] & [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 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.

When it is time to replace batteries, the low-battery indicator will
be displayed for the selected channel.

HOW TO USE THE T ABLE ST AND 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.

The remote sensor comes with a wall mount holder and a table stand.

THE RESET BUTTON

This button is used when the unit is operating in an unfavorable
way or malfunctioning. To return all user programmed settings to
their original factory values, press [ RESET ] by using a blunt
stylus to hold down the button.

GETTING STA RTED

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.

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 300
feet (100 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.

BATTER Y INST ALLA TION: MAIN UNIT

1. Gently lift up the tab on the battery compartment door.

2. Insert four (4) UM-3 or “AA” size batteries.

3. Replace the battery compartment door.

BATTER Y AND CHANNEL INST ALLA TION:

REMOTE UNIT

The remote thermo-hygro sensor unit uses two (2) UM-3 or “AA”
size batteries.

Follow these steps to install / replace batteries:

1. Remove the screws on the battery compartment.

2. Select the channel number on the [CHANNEL] slide switch.

3. Select the temperature display unit on the °C/°F slide switch.

4. Insert the batteries strictly according to the polarities shown
therein.

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

Replace the batteries when the low-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.
