BATTERIES
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
of the unit.
2. Remove the battery cover and insert
the batteries as indicated by the
polarity symbols (+ and -) marked
inside the battery compartment.
3. Replace the battery door and fasten
the screw.

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
weather.
PRESSURE TREND
Stored memory of the barometric pressure
changes are displayed on the chart, in
5 steps indicating the pressure 1,3,6,12
and 24 hours ago. This chart is plotted by
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%.
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/
infopage/elevation.htm.

the weather station selects between hPa/
mb and inHg. To select hPa/mb, set the
switch to hPa/mb. To select inHg, set the
switch to inHg.

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 radio-
control 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.
SET CLOCK
You only need to perform this task
if you have disabled RF signal reception.

Note: After replacing the batteries,
the whole display will be
turned on for about 3 seconds
and then show the following:
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
indicating the weather forecast for 12 or
24 hours ahead, for an area with a radius
of about 18-30 miles.

indicator will turn on with the altitude
setting flashing (display in meter).
The accuracy of a general pressure-
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

indicator flashing (about 15 minutes )
until a new sampling takes place and
the pressure reading is then
compensated with the new altitude.
