SET ALTITUDE

1. Press and hold the SET button for

2 seconds to set the altitude. The 'ALT '
indicator will turn on with the altitude
setting flashing (display in meter).

a. Weather forecast shows slightly

cloudy weather (a sun with the cloud

indicator)
b. Pressure trend shows steady.
c. Barometric pressure shows the current

reading. The unit takes about 24 hours

to store the barometric pressure date.

Until that time has elapsed, the

pressure trend and weather forecast

symbols may not reflect actual

weather forecast for your area.

WEATHER FORECAST SYMBOLS

Your weather station detects barometric
pressure changes and the LCD displays
the illustsrated weather symbols which

Important:

1. The accuracy of weather forecasting

when using pressure trend alone is

about 70 to 75 percent and, therefore,

we cannot be held responsible for any

inconveniences caused by an

inaccurate weather forecast.

2. The weather forecasts symbols reflect

forecast 12-24 hours in the future and

not the current weather condition.

3. A ' Sunny ' forecast reflects fine clear

based weather forecast is about 70%
to 75%.

Increase/decrease the altitude in steps
of 10 meter by pressing

or

button.

2. Press the SET button again to set

the altitude. At this time the previous
pressure display will reappear. If the
altitude has been changed, the ' ALT '
indicator flashing (about 15 minutes )
until a new sampling takes place and
the pressure reading is then
compensated with the new altitude.

3. Press the SET button 6 times to

confirm the setting you just entered or
wait for one minute for automatic exit.

Note: For monitoring the local
barometric pressure reading, the user
needs to select the 0 meter
( preset value ) for the altitude setting.

For monitoring the Sea Level
barometric pressure reading at certain
altitude, the user needs to select the
local altitude (-100 to 2500 meters i.e.

-328 to 8223 feet) for the altitude
setting. The BHB-613 requires entry
of elevation in meters not feet.
Therefore, to convert feet to meters,
multiply feet by 0.3048.

To determine your location elevation,
please either contact your local library,
TV/ radio weather forecaster, or via
Intenet at www.worldatlas.com/aatals/

The unit uses four UM-4 "AAA" size

batteries. If the " " indicator appears,
remove the exhausted batteries and follow

these steps to replace the batteries:

1. Unscrew the battery door at the bottom

comparing the past barometric pressure
to the present pressure.

This gives you the pressure trend over the
last 24 hours. The weather will be getting
better (worse) if this chart shows the bar
marks moving up (down) towards the
present time.

Important:

It is only possible to measure the
barometric pressure trend properly if your
barometer remains at the same altitude.

When moving around at different altitude
within a short time period, the air pressure
changes. The barometric pressure reading
is precise only if the barometer has
remained at a constant altitude for
24 hours.

However, please note that the accuracy
of a weather forecast based on barometric
pressure reading is considered to be about
70-75%.

-To get the bar chart display, press the

RESET button once.

Note: Either action will reset the unit and

the previous readings/setting will be
lost.

RF SIGNAL RECEPTION

The BHM-612A is designed to
automatically synchronize its current time
and date when within range of the U.S.
Atomic Clock.

When the unit is within range, its radio­control mechanism will override all manual
settings. The benefit of a RF controlled
clock is sustained accuracy without the
need of manual adjustment.

Complete signal reception generally takes
about 2 to 10 minutes, depending on the
strength of the radio signal. When the
reception is completed, the signal display
will be stable. After that, the periodical
scanning will only take a few seconds.

For better reception of radio signals, place
the clock away from metal objects and
electrical appliances to minimize
interference.

ACTIVATE / DEACTIVATE RF SIGNAL

To disable the automatic signal reception
feature and cause the BHM-612A to
operate as a quartz clock, hold down
ZONE for three seconds.

To enable the feature again, hold down the
UP button for three seconds. The RF signal
display will start scanning to initiate
reception automatically.

BEFORE YOU BEGIN

To ensure proper setup, please note the
following before you start:

• Assign different channels to different
remote units.

• Insert batteries in remote units before
doing so for the main unit (see
instructions for battery installation).

• Place the main unit as close as
possible to the remote unit

• Reset the main unit after installing
batteries. This will ensure easier
synchronization between the
transmission and reception of signals.

• Position the remote unit and main unit
within effective transmission range,
which, in usual circumstances, is
65 to 100 feet.

NOTE

Refer to the REMOTE SENSOR

section for sensor setup instructions.

BATTERIES

The Thermo Hygrometer uses 2 UM-3
("AA") alkaline batteries.

1. Remove the screw to open the battery
door.

2. Insert the batteries strictly according
to the polarities.

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

4. Replace the battery door and fasten
the screw.

5. Replace the batteries when the low­battery indicator of the indoor
temperature lights up (Repeat the
steps described in "Before You Begin",
above)

shows when batteries are low for the

main unit or for the selected remote unit.

GETTING STARTED

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 upper window and the
respective humidity reading on the lower
window. The main unit will automatically
update its readings at about 40-second
intervals.

If no signals are received, blanks "---" will
show and the RF signal indicator will not
show.

SEARCH FOR A SENSOR SIGNAL

Press and hold IN / REMOTE 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.

DISPLAY 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 under the readings.

INDOOR UNIT

Press IN/REMOTE until "in" is displayed
under the readings.

REMOTE SENSOR

Press CHANNEL until the appropriate
remote sensor channel is displayed under
the readings.

If no readings are received from one
particular channel for more than 15
minutes, blanks "---" will be displayed until
further readings are successfully
searched. Check the remote sensor to
ensure that t is secure and that the correct
channel has been selected. Optionally,
press and hold IN/REMOTE for 2-seconds
to enforce a search.

MAXIMUM / MINIMUM TEMPERATURE
/ HUMIDITY

The maximum and minimum recorded
temperature and humidity readings will
automatically be stored in the memory.

DISPLAY MAXIMUM / MINIMUM
MEMORY

1. Select the channel to be checked.

2. Press MEM / CLEAR once to display

the maximum reading and again to
display the minimum reading. The
respective indicators, MAX or MIN will
show.

CLEAR MEMORY

Press and hold MEM / CLEAR for
2-seconds. The current temperature and
humidity will be saved as the min / max
values until new records are set.

TEMPERATURE DISPLAY

Slide the °C/°F switch into the desired
position to select °C (Centigrade) or °F
(Fahrenheit) degrees display. The switch
is located on the bottom of the unit.

NOTE

The switch on the main unit over­rides any selection you may make for the
remote sensor (THGR238N).

button.

SEARCH FOR SENSOR

To search for a sensor, press IN /
REMOTE.

NOTE

If the sensor is still not found,
check the batteries, obstructions, and
remote unit location.

NOTE

Signals from household devices
such as doorbells, electronic garage doors,
and home security systems may cause
temporary reception failure. This is normal
and does not affect general product
performance. The reception will resume
once the interference ends.

NOTE

Battery performance, and subsequently
the effective range, may be affected by
freezing temperatures.

30 meters.

Note: The effective range may be
limited by building materials and the
position of either the main unit or
remote sensors. Try various set-up
arrangements for best result.

Though the sensor is weatherproof, and
is meant for use outside, it should be
placed away from direct sunlight, rain, or
snow.
