Radio-controlled Clock : The unit starts synchronizing the clock after the 1st channel of
the wireless sensor begins to send its information to the main unit. (This is called
registration.) The built-in antenna receives the official time signal from the US Govern­ment's National Institute of Standards and Technology. A microchip translates the time
signal and adjusts the time display for the correct time, and date.

Manually Setting the Time and Date:

1) Press and hold the “SET” button, and the year display will flash on the screen. Using
the “+” and “– ” buttons set the year. When the correct year is entered, press and
release the “SET” button to confirm the setting.

2) Once you have confirmed the year, follow the same procedure to set the month, date,
hour, minute, 12 or 24-hour time preference, and DST (Daylight Saving Time).

NOTE: You cannot change any settings manually if the clock is attempting to synchro­nize. Allow the clock to finish the cycle, and then manual changes can be made if the
clock has not automatically acquired the signal and set itself to the correct time.

Time Zone:

Note: Default setting is Pacific Time. If you live outside of the Pacific Time Zone, you will
need to set your Time Zone using the following procedure:

1) Press and hold the “– / C/F” button on the front of the clock for three seconds. The
area of the clock where the seconds are usually displayed will be replaced with the letter
for the time zone it is currently set in.

2) If set to the default setting, you will see a flashing letter “P” on the screen after
pressing and holding the “– / C/F” button. Press and release the “– / C/F” button until the
letter shown corresponds to your time zone:

P = Pacic M = Mountain C = Central E = Eastern

Once your zone is displayed, there is nothing more you need to do. After about 3
seconds, the seconds will once again be displayed on your clock.

The antenna icon ( ) will flash on and off during synchronization. If the icon disap­pears, this indicates that the radio signal is not available. If you are unable to obtain a
signal after a long period of time, try placing the base unit away from sources of
interference such as computers, televisions, cordless phone bases, and other electronic
items.

Note: The synchronization process can take 24-72 hours.

Celsius/Fahrenheit:
Press and release the “–” (minus) button. A beep sounds, and the display will change to
either Fahrenheit or Celsius.

Barometer Set Up:

When the main unit power comes on, the pressure section will display 1013 for 60
seconds. The digital barometer will calculate and forecast the weather conditions. Your
instrument will not provide a reliable forecast unless your current barometric pressure
is set. See page 8 for barometric pressure adjustment information.

7 6

Adjust the barometric pressure to reect your current conditions:
NOTE: Please see http://weather.unisys.com/surface/sfc_con_pres.html to help set

and adjust the barometric pressure.

1) Hold “PRESSURE” button for 3 seconds

2) Press “P+” , and/or “P-” to adjust the air pressure according to the current pressure.

3) Press the “PRESSURE” button to confirm the setting

SETTING THE ALARM:

1) Hold “ALARM” for 3 seconds.

2) The hour number(s) flash. Press “+” or “-” to enter the desired hour. Press
“ALARM” to confirm the hour setting.

3) The minute number(s) flash. Press “+” or “-” to enter the desired minute.
Press “ALARM” to confirm the minute setting.

Moon Phase:

The moon phase will automatically display based on the calender date. The moon phase
display will scroll from left to right, and pause for about 5 seconds to display the current
moon phase. NOTE: the moon phase will not be correct unless the date and year are
programmed correctly.

OTHER ADJUSTMENTS

Changing the Pressure Units: To change the scale between mb (milibars) hPA

(hectoPascals) and inHg (inches of mercury), hold “P-” for three seconds.

View Pressure History: To view air pressure from 0 (current) to the past 12 hours, press the
“PRESSURE” button. The hour is displayed in the small box in the pressure portion of
the upper display. Each time you press “PRESSURE”, the value changes to that of the
previous hour.

NOTE: The sample base station Upper Display (illustrated in section 5) shows what the
pressure is, the current hour being zero (0). This pressure history is available only after
the barometer has operated and kept pressure data for 12 continuous hours.

Barometer History Graph: The bar chart just below the air pressure display, shows the
pressure readings (range from +0.24 inHg to –0.24 inHg/ –8 hPa mb to +8 hPa mb) of
the current and past 1, 2, 3, 6 and 12 hour periods.

WEATHER FORECASTING

The main unit predicts weather conditions of the next 12 – 24 hours based on the
changes in atmospheric pressure. The coverage area is approximately 19-31 miles (30 –
50 km). The weather forecast is based on atmospheric pressure changes and is approxi­mately 70-75% correct. As weather conditions cannot be 100% correctly forecasted, we
cannot be responsible for any loss caused by an incorrect forecast.

STORMYRAIN/SNOWCLOUDYPARTLY CLOUDYSUNNY

To view the alarm time, press the “ALARM” button during the normal operating mode.
Alarm time will display for five seconds. Then, the current time is displayed.

To Turn the Alarm On and O: Press the “+” button during the normal operating mode.

To Turn o the Alarm for One Day: To turn the alarm off for one day, press the “ALARM”

button when the alarm sounds

Snooze:

When the alarm sounds, press the “SNOOZE” button to trigger the snooze feature. The
alarm is silenced for five minutes. Then, it will sound an alarm again.

MIN/ MAX MEMORY:

Press the “MEMORY” button to view the maximum values (Inside/Outside Temperature
and Humidity) for 5 seconds. Press the “MEMORY” button again to view the minimum
memory.

The memory will automatically refresh every 24 hours.

NOTE:The air pressure record will not be cleared manually, but instead will be cleared

automatically every 12 hours.
