GETTING STA RTED
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.

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
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.
T o display temperature / humidity r eadings 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] 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, 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.

ABOUT RADIO RECEPTION
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.
