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 will ensure

4
EN
easier synchronization between the transmission and reception
of signals.
4. Position the remote unit and main unit within effective
transmission range, which, in usual circumstances, is up to 100
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.
BATTERYINSTALLATION:MAINUNIT
1. Gently lift up the tab on the battery compartment door.
2. Insert four UM-3 or “AA” size batteries.
3. Replace the battery compartment door.

THERESET BUTTON
This 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.
GETTINGSTARTED
Once batteries are placed in a given remote sensor unit, it will start
transmitting information at 40-second intervals.
Also, 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 top line and the respective humidity
reading on the bottom line. The main unit will automatically update
its readings at about 40-second intervals.

6
EN
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
readings 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.
To display temperature / humidity readings from the main unit:
• 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] & [MEMORY] toenforceanimmediate
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, 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 and humidity readings
will resume once the interference recedes.

ABOUTRADIORECEPTION
The BAR122HGN is designed to automatically synchronize its
calendar clock once it is brought within range of the Frankfurt
DCF77 radio signal.
When the BAR122HGN 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 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 backs place.
For better reception, place the clock away from metal objects and
electrical appliances to minimize interference.
