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.

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). 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 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

ALARM CLOCK (BHM612A)
EUP BUTTON
-Increases the value of a setting by one unit
FZONE BUTTON
-Press to sequence through the 4 U.S. time-zones: Pacific, Mountain, Central or Eastern.
GALARM BUTTON
-Changes the display and operating status of the alarm clock
HRESET BUTTON

BATTERIES
1.Open the battery compartment by removing the screw at the bottom of the unit.
2.Pull out the battery holder and insert two AAA-sized (UM-4) batteries in accordance with the polarities shown.
3.Slide back the battery holder into the compartment and fasten the screw.
4.Press RESET with a blunt stylus.
5.When the low battery indicator [ 
] appears on the display, follow the above procedures to replace the unit with new batteries.
Note The unit will automatically search for the radio signal when batteries are first installed. When the BHM-612A is new and just out of the box, allow up to 72 hours for the unit to receive the US Atomic Clock signal. To facilitate
To display the alarm time in the secondary window, press ALARM once. Press MODE / SET to display the date.
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.

Received
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.
SET ALARM
To set the alarm time:
1.Press ALARM to display the alarm time.
2.Press and hold ALARM for two seconds. Hours digits will flash.
3.Set the hours using UP .
4.Press ALARM. Minutes digits will flash.
5.Set the minutes using UP.
6.Press ALARM to save and exit. The alarm clock will be activated automatically during the setting procedure.
To activate or deactivate the alarm during normal display.
•Press ALARM to display the alarm time.
•Press ALARM to change the status of the alarm. The respective indicator will appear.
When the alarm goes off, the alarm sound will gradually increase in volume and speed. The alarm will continue to sound for approximately two minutes unless interrupted when any button is pressed. If the alarm is not interrupted, after 2 minutes the alarm will silence itself and reactivate after approximately eight minutes.

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%.
