INTRODUCTION
Congratulations for purchase of the JM828WF Weather Forecast
RF Clock.
The JM828WF is a multifunction Radio Frequency (RF) control-
led clock. When brought within radio signals generated from
Frankfurt, Germany (DCF77) (Model JM828WF) or from Rugby,
UK (MSF60) (Model JM828WFU), the unit will automatically
synchronize 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.

BATTERY INFORMATION
The unit requires four UM4 or AAA-size batteries for operation.
How to insert batteries:
1. Press the door tab and click open the door.
2. Insert the batteries strictly according to the polarities shown
therein.
3. Replace the door until it clicks in place.
Replace the batteries when the battery low indicator lights up.
ABOUT RADIO RECEPTION
The JM828WF is designed to automatically synchronize its current
time and date when brought within range of the DCF77 or the
MSF60 (Model JM828WFU) RF signal.
When the unit is within range, its radio-control mechanism will
override all manual settings.
When the unit is receiving radio signal, the reception icon will
start to blink. The reception icon will show either strong, weak
or no signal depending on the strength of the radio signal. A
complete reception generally takes about two to 10 minutes.
When the reception is completed the reception icon will stop
blinking. The reception icon will show [ ] for no reception or
[ ] for successful reception.
For better reception of radio signals, place the clock away from
metal objects and electrical appliances to minimize interference.
To disable the auto-reception feature, hold down the [ ] and
[] 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 [ ] 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 is not received, then set the time manually (see
below, How To Set The Calendar Clock Manually).
TIME DISPLAY MODES
When the calendar is displayed, press CLOCK once to toggle
between hour, minute, second mode or the hour, minute, day-of-
the-week mode.
When the alarm-time is displayed, pressing CLOCK once will
display the calendar instead. Then use the button again to toggle
the time modes.

ALARM AND SNOOZE FUNCTION
When the alarm function is 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 JM828WF 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, is 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 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.
