Congratulations for purchase of the JM828WF Weather Forecast I
RF Clock.
The JM828WF 1s a multifunction Radio Frequency (RF) control-
led clock. When brought within radio signals generated from
Frankfurt, Germany (DCF77) the unit will automatically syn-
chronize with the current time and date.
The JM828WF can indicate weather forecasts and pressure change
trends.
Other features include a daily crescendo alarm with an eight-
minute snooze function, and extra-large display.

ABOUT RADIO RECEPTION
The JM828WF 15 designed so it can synchronize the clock once
it is brought within range of the Frankfurt DCF77 radio signal.
When the JM828WF 1s within range, its radio-control mechanism
will override all manual settings.
When the unit is receiving a radio signal, the Antenna Icon
[ | ]willstart to blink. A complete reception generally takes
between two to ten minutes, depending on the strength of the
radio signal. After that the scanning only takes a few seconds.
When reception is complete, the Antenna Icon [ | ] will stop
blinking. The strength of the reception since the last scan will be
indicated.

Г WEAK

= T= RECEIVING
For better reception, place the clock away from metal objects and
electrical appliances to minimize interference.
To disable the auto-reception feature, hold down the [ A ] and
[ W ] buttons simultaneously for two seconds. The Antenna Icon
[ | } Will appear but it will not blink. The unit will NOT respond to
radio signals.
To enable the feature again, hold down the buttons again. The
Antenna Icon [ [1] signal will start blinking to initiate
reception automatically.

Note: Interference from sources such as TV sets can affect the
signal. If, after batteries have been inserted for ten minutes, the
DCF-77 signal 1s not received, then set the time manually (see
below, How To Set The Calendar Clock Manually).

ALARM AND SNOOZE FUNCTION
When the alarm function 1s active, the unit will alarm at the set
time.
Resulting from the crescendo function, the alarm initially starts
gently and increases in intensity in three stages. Without inter-
ruption, the alarm will activate for one minute.
To stop the alarm, press any key. However, if the SNOOZE button
is pressed, the SNOOZE function will be triggered. The alarm
will stop for eight minutes before activates again.
INDOOR TEMPERATURE
The JMB28WF displays temperature in Centigrade (°C), and is
capable of measuring temperatures within the -5°C and +50°C
range. If the temperature goes above or below these levels, the
display will show “-5°C” or “+50°C”.
HOW TO READ THE PRESSURE TREND
The JM828WF gives a pressure trend for the last hour. As illus-
trated below, a rising trend (arrow) indicates improving weather.
Deteriorating weather conditions are indicated with a falling
trend (arrow).

WEATHER FORECAST FUNCTION
The JM828WF detects barometric pressure changes and displays
the illustrated weather symbols that indicate weather forecasts
for 12 to 24 hours. The radius of the forecast is approximately 30
- 50 km.

Important:
1. The accuracy of weather forecasting, when only using pres-
sure trends, 1s approximately 70 to 75 percent.
2. The weather forecast symbols may not reflect current weather
condition. The symbols are forecasting the future.
3. A ‘SUNNY’ forecast covering the nighttime reflects fine clear
weather.
HOW TO RESET THE UNIT
Press RESET to return all settings to the factory values, which are
1997 for year, 1-1 (1st of January) for date, 12:00 for time and
06:00 for the alarm, which will be deactivated.
The button is required only when the unit is not operating in a
favorable way, such as in the rare case of a malfunction.
HOW TO WALL MOUNT OR
